Solutions - Chapter 66-1: PersonUse a dictionary to store information about a person you know. Store their first name, last name, age, and the city in which they live. You should have keys such as first_name, last_name, age, and city. Print each piece of information stored in your dictionary.Output:6-2: Favorite NumbersUse a dictionary to store people’s favorite numbers. Think of five names, and use them as keys in your dictionary. Think of a favorite number for each person, and store each as a value in your dictionary. Print each person’s name and their favorite number. For even more fun, poll a few friends and get some actual data for your program.Output:6-3: GlossaryA Python dictionary can be used to model an actual dictionary. However, to avoid confusion, let’s call it a glossary.Think of five programming words you’ve learned about in the previous chapters. Use these words as the keys in yourglossary, and store their meanings as values.Print each word and its meaning as neatly formatted output.You might print the word followed by a colon and then itsmeaning, or print the word on one line and then print itsmeaning indented on a second line. Use the newline character ('\n') to insert a blank line between each word-meaning pair in your output.Output:6-4: Glossary 2Now that you know how to loop through a dictionary, clean up the code from Exercise 6-3 (page 102) by replacing your seriesof print statements with a loop that runs through the dictionary’s keysand values. When you’re sure that your loop works, add five more Python terms to your glossary. When you run your program again, these new words and meanings should automatically be included in the output.Output:6-5: RiversMake a dictionary containing three major rivers and the country each river runs through. One key-value pair might be 'nile': 'egypt'.∙Use a loop to print a sentence about each river, such as The Nile runs through Egypt.∙Use a loop to print the name of each river included in the dictionary.∙Use a loop to print the name of each country included in the dictionary.Output*:*Sometimes we like to think of Alaska as our own separate country.6-6: PollingUse the code in favorite_languages.py (page 104).∙Make a list of people who should take the favorite languages poll. Include some names that are already in the dictionary and some that are not.∙Loop through the list of people who should take the poll. If they have already taken the poll, print a message thanking them for responding. If they have not yet taken the poll, print a message inviting them to take the poll.Output:6-7: PeopleStart with the program you wrote for Exercise 6-1 (page 102). Make two new dictionaries representing different people, and store all three dictionaries in a list called people. Loop through your list of people. As you loop through the list, print everything you know about each person.Output:6-8: PetsMake several dictionaries, where the name of each dictionary is the name of a pet. In each dictionary, include the kind of animal and the owner’s name. Store these dictionaries in a list called pets. Next, loop through your list and as you do print everything you know about each pet.Output:6-9: Favorite PlacesMake a dictionary called favorite_places. Think of three names touse as keys in the dictionary, and store one to three favorite places for each person. To make this exericse a bit more interesting, ask somefriends to name a few of their favorite places. Loop through the dictionary, and print each person’s name and their favorite places.Output:6-10: Favorite NumbersModify your program from Exercise 6-2 (page 102) so each person can have more than one favorite number. Then print each person’s name along with their favorite numbers.Output:6-11: CitiesMake a dictionary called cities. Use the names of three cities askeys in your dictionary. Create a dictionary of information about each city and include the country that the city is in, its approximate population, and one fact about that city. The keys for each city’s dictionary should be something like country, population, and fact.Print the name of each city and all of the information you have stored about it.Output:。

Python数据分析笔记#4错误和异常处理原创Yuan的学习笔记2021-02-15 17:06:56Yuan的学习笔记作者 Yuan错误和异常处理我们写程序时常常会遇到各种错误，比如下面一个例子，当把一个字符串转化为浮点数类型时，程序就会报错：In [1]: float('1.2345') Out[1]: 1.2345 In [2]: float('something')---------------------------------------------------------------------------ValueError Traceback (most recent call last) <ipython-input-2-2649e4ade0e6> in <module>----> 1 float('something')ValueError: could not convert string to float: 'something'最下面的ValueError告诉你，不能把字符串转化为浮点数。
当有用户使用我们编写的程序时可能因为某些原因(比如不小心或不会用)导致了程序出错，我们可能需要更优雅的处理这些错误。
比如我们可以写一个函数：def attempt_float(x): try:return float(x)except:print('could not convert string to float')return x当float(x)出异常的时候，会执行下面except的部分：In [4]: attempt_float('1.2345') Out[4]: 1.2345In [5]: attempt_float('something') could not convert string to floatOut[5]: 'something'若我们输入了一个元组进去：In [6]: float((1, 2))---------------------------------------------------------------------------TypeError Traceback (most recent call last) <ipython-input-6-82f777b0e564> in <module>----> 1 float((1, 2))TypeError: float() argument must be a string or a number, not 'tuple'我们可以看到这次抛出的异常不是ValueError而是TypeError(类型错误)，我们可以只处理ValueError的错误：def attempt_float(x):try:return float(x)except ValueError: print('could not convert string to float') return x当要把'banana'转化为浮点数时(ValueError)：In [9]: attempt_float('banana')could not convert string to floatOut[9]: 'banana'当要把元组转化为浮点数时(TypeError)：In [10]: attempt_float((1,2))---------------------------------------------------------------------------TypeError Traceback (most recent call last) <ipython-input-10-102527222085> in <module>----> 1 attempt_float((1,2))<ipython-input-8-3ff52c4ecd95> in attempt_float(x) 1 def attempt_float(x): 2 try:----> 3 return float(x) 4 except ValueError: 5 print('could not convert string to float') TypeError: float() argument must be a string or a number, not 'tuple'我们也可以用元组包含多个异常：def attempt_float(x):try:return float(x)except (ValueError, TypeError):。

aicepython7级知识点一、数据结构。
1. 列表（List）- 列表的创建：可以使用方括号 [] 来创建列表，例如 `my_list = [1, 2, 3, 'a', 'b']`。
- 列表的索引：从0开始，可以使用正向索引和反向索引。
正向索引如`my_list[0]` 得到第一个元素，反向索引如 `my_list[-1]` 得到最后一个元素。
- 列表的切片：`my_list[start:stop:step]`，例如 `my_list[1:3]` 得到索引为1和2的元素。
- 列表的操作。
- 追加元素：使用 `append()` 方法，如 `my_list.append('c')`。
- 插入元素：使用 `insert()` 方法，如 `my_list.insert(2, 'new')` 在索引2的位置插入'new'。
- 删除元素：可以使用 `del` 语句（如 `del my_list[0]`）或者 `remove()` 方法（如 `my_list.remove('a')`，删除指定值的元素）。
- 列表的排序：使用 `sorted()` 函数返回一个新的排好序的列表，或者使用列表的 `sort()` 方法对原列表进行排序，例如 `my_list.sort()`。
2. 元组（Tuple）- 元组的创建：使用圆括号 ()，例如 `my_tuple=(1, 2, 3)`。
- 元组是不可变的数据类型，一旦创建不能修改元素。
但如果元组中的元素是可变类型（如列表），则可以修改该可变元素的内容。
- 元组的索引和切片操作与列表类似。
3. 字典（Dictionary）- 字典的创建：使用花括号 {}，例如 `my_dict = {'key1': 'value1', 'key2': 'value2'}`。

Ministry of Transport, MalaysiaAPPENDIX 1.6C – 9M-MRO RADIO LICENCE1 of 1MH370/01/15Malaysian ICAO Annex 13 Safety Investigation Team for MH370 Ministry of Transport, MalaysiaAPPENDIX 1.6D – ELT ACTIVATION SUMMARY (SOURCE: ICAO)Emergency Locater Transmitter ActivationThe parameters in the query for the status of Emergency Locator Transmitters (ELT) after an occurrence were set at:Dates between 1 January 1983 and 30 June 2014 (approximately 30 years), including all occurrences (accidents and incidents) involving aircraft in the mass group 5 701 kg and above and records with descriptive factors and ELT parameters that have value.The query found 403 records in the ADREP database in which a response was inserted relating to ELTs. Of these occurrences 257 were classified as accidents. Due to incidents being less severe, a lower probability of ELT implications are expected. The query then focused on accidents. The following table indicates the aircraft mass groupings of the aircraft involved in accidents:Aircraft mass group Accidents5 701 to 27 000 Kg 16127 001 to 272 000 Kg 87> 272 000 Kg 9Total 257The taxonomy for the attribute to indicate the status of the ELT (whether it worked as designed or why it did not work) was used to compile the following table: (* after 1994)APPENDIX 1.6D – ELT ACTIVATION SUMMARY (SOURCE: ICAO)ELT status CasesBattery failed 14Damaged 11Internal failure 5Not activated 22Not carried 84 (12)*Operated effectively 39Other 21Submerged 1Terrain shielding 1Unknown 59Total 257In 39 cases of the 257 accident records, the ELT operated effectively, which implies that 15% of the ELTs operated effectively. The data indicated that in 84 cases, no ELT was carried. Considering that provisions for the carriage of ELTs became applicable in Annex 6 on 10 November 1994, the no ELT carried data was evaluated to determine the situation after 1994 (past 20 years approximately) and the number reduced from 84 to 12.29 July 20141.6E.1 Air Conditioning and PressurisationThe aircraft has two air conditioning systems divided into left pack and right pack. Engine bleed air provides the pneumatic source for air conditioning and pressurisation.Two electronic controllers provide pack and zone control. Each controller has two channels that alternate command cycle. Cockpit and cabin temperature selection is monitored and the Air cycle machine and temperature control valves will be commanded to deliver temperature conditioned air to the various cabin zones.Conditioned air is also used for electronic equipment cooling. This is supplied through a series of pneumatic valves with supply and exhaust fans. Exhaust air from the equipment cooling flow is routed to the forward cargo and used for forward cargo compartment heating.Two cabin pressure controllers regulate the aircraft pressurisation and command the pneumatic system. System operation is automatic and works in conjunction with the forward and aft outflow valves that are used for pressurisation. The outflow valves can also be manually operated.1.6E.2 Autopilot Flight Director System (AFDS)The autopilot is engaged by operation of either of two A/P pushbutton switches on the Mode Control Panel (MCP) located on the glareshield panel (Figure 1.6EA). Once engaged the autopilot can control the aircraft in various modes selected on the MCP. Normal autopilot disengagement is through either control wheel autopilot disengage switch. The autopilot can disengage if the flight crew override an autopilot command through the use of the rudder pedals or control column. The autopilot can also be disengaged by pushing on the A/P Disengage Bar on the MCP. The AFDS consists of three autopilot flight director computers and the MCP.1.6E.2.1Roll ModesThe following AFDS roll modes are available during climb, cruise and descent (Figure 1.6EB below ):a) Lateral Navigation (LNAV)Pushing the LNAV switch arms, selects or disarms the LNAV mode. The commands come from the active Flight Management Computing Function (FMCF) when there is a valid navigation data base and an active flight plan. The Control Display Units (CDUs) can send LNAV steering commands when there is no active FMCF. The AFDS use this priority to select a CDU command: ∙ Left, if valid∙ Centre, if left not valid∙ Right, if left and centre not valid.The CDU is the primary control and display interface for the FMCF. The CDU is used to enter flight plan data and performance data. The CDU can also be used to manually tune the navigation radios and access maintenance pages.b) Heading Hold (HDG HOLD/Track hold (TRK HOLD)Pushing the Heading/Track Hold switch selects Heading or Track hold. In this mode, the aircraft holds either heading (HDG) or track (TRK). If the HDG/TRK display on the MCP shows TRK, the aircraft holds track. If the HDG/TRK display on the MCP shows HDG, the aircraft holds heading.b) Heading select (HDG SEL)/Track select (TRK SEL)Pushing the Heading/Track Select switch (inner) selects Heading select or Track selectmodes. In this mode, the aircraft turns to the heading or track that shows in theheading/track window. Pushing the Heading/Track (HDG/TRK) Reference switchalternately changes the heading/track reference between heading and track. Rotating theHeading/Track selector (middle) sets the heading or track in the heading/track window. Ifthe HDG/TRK display shows HDG, the aircraft goes to and holds the heading that showsin the heading/track window. If the HDG/TRK display shows TRK, the aircraft goes to andholds the track that shows in the heading/track window. Rotating the Bank Limit selector(outer) sets the bank limit when in the Heading select or Track select modes. In theAUTO position, the limit varies between 15 - 25 degrees, depending on True Airspeed.When the other detented positions are selected, the value is the maximum, regardless ofairspeed.1.6E.2.2 Pitch ModesThe following AFDS pitch modes are available during climb, cruise and descent (Figure1.6EC below).a) Vertical navigation (VNAV)Pushing the VNAV switch arms, selects or disarms the VNAV mode. The VNAV mode isa mix of throttle and elevator commands that control the vertical flight path. The FMCFvertical steering commands come from the active FMCF based on the navigation dataand the active flight plan.b) Vertical speed (V/S)/Flight Path Angle (FPA)Pushing the V/S-FPA switch selects the V/S or FPA mode. Rotating the V/S-FPAselector Up or Down sets the vertical speed or flight path angle in the verticalspeed/flight path angle window. Pushing the V/S-FPA Reference switch alternately changes vertical speed/flight path angle window references between verticalspeed and flight path angle. The vertical speed or flight path angle command is anelevator command. The pilot uses this mode to change flight levels. The pilot must setthe engine thrust necessary to hold the vertical speed or flight path angle command.When the V/S/FPA display shows V/S, the aircraft goes to and holds the vertical speedthat shows on the vertical speed/flight path angle window.Figure 1.6EC Vertical Mode Switches and Indicatorsc) Flight Level Change (FLCH)Pushing the FLCH switch selects the Flight level change speed mode. The FLCH command is a mix of thrust and elevator commands to change flight levels. When the IAS/MACH display shows IAS, the elevator command holds the speed that shows on the IAS/MACH window. When the IAS/MACH display shows MACH, the elevator command holds the MACH that shows on the IAS/MACH window. Rotating the IAS/MACH selector sets the speed in the IAS/MACH window. Pushing the IAS/MACH Reference switch alternately changes the IAS/MACH window between IAS and MACH.The Thrust Management Computing Function (TMCF) supplies the engine thrust commands.d) Altitude Hold (ALT)Pushing the Altitude Hold switch selects the Altitude hold mode. In this mode, the aircraft holds the barometric altitude present when the pilot pushes the altitude HOLD switch.1.6E.2.3 Landing ModesThe following AFDS functions are available for landing:a) Localizer (LOC)The LOC mode captures and holds the aircraft to a localizer flight path.b) Glideslope (G/S)The G/S mode captures and holds the aircraft to a vertical descent flight path.c) Flare (FLARE)The flare mode controls the aircraft to a smooth touchdown at a point past the glideslope antenna. This is a computed command and is not part of the glideslope mode.d) Runway AlignmentIn crosswind conditions, the runway alignment mode supplies roll and yaw control to decrease the aircraft crab angle for touchdown. The runway alignment mode also includes roll and yaw control for an engine failure in approach during autoland.e) Rollout (ROLLOUT)After touchdown, the rollout mode controls the aircraft to the runway centre line. Aircraft deviation from the localizer centre line supplies rudder and nose wheel steering signals.f) Go-Around (TO/GA)The go-around mode controls roll and pitch after an aborted approach. Also, the TMCF controls thrust during go-around.Pushing the Localizer (LOC) switch arms, disarms or captures the localizer as roll mode.Pushing the Approach (APP) switch arms, disarms or captures the localizer as roll mode and glidepath (G/S) as pitch mode (Figure 1.6DD below).Figure 1.6ED Approach Mode Switches1.6E.3 Autothrottle (Thrust Management Computing Function – TMCF)The autothrottle (A/T) commands the thrust levers to achieve an engine thrust setting, or a selected airspeed. The A/T is armed by the operation of two toggle switches and engaged by the operation of a pushbutton switch on the MCP (Figure 1.6DE below).Figure 1.6EE Autothrottle SwitchesDuring normal flight operations, the flight crew uses the TMCF to perform several routine or normal operations and tasks. These operations or tasks relate to autothrottle modes. The autothrottle (A/T) modes operate in these flight phases: ∙ Take-off (TO) ∙ Climb (CLB) ∙ Cruise (CRZ) ∙ Descent (DES) ∙ Approach (APP) ∙Go-around (GA)Autothrottle functions that relate to flight phases are flare retard during autoland and autothrottle disconnect. Autothrottle thrust mode annunciations relate to pitch mode annunciations on the Primary Flight Display (PFD). 1.6E.3.1Autothrottle Modesa) Take-off (TO)In TO, the autothrottle controls thrust to the take-off thrust limit. The autothrottle mode annunciation on the PFD is thrust reference (THR REF). At a threshold air speed, the autothrottle mode annunciation on the PFD changes to HOLD.b) Climb (CLB)i. These are the three autothrottle mode selections in climb: ∙ Vertical navigation (VNAV) ∙ Flight level change (FLCH)∙ Autothrottle (MCP) speed mode or thrust mode.ii. These are the autothrottle mode annunciations for these modes: ∙ THR REF when VNAV engages∙THR when FLCH engages∙SPD or THR REF when autothrottle mode engages.The autothrottle speed mode only engages when VNAV, FLCH, and TO/GO are not active and the aircraft is in the air.c) Cruise (CRZ)i. These are the two autothrottle modes in cruise:∙VNAV∙Autothrottle speed mode.ii. These are the autothrottle mode annunciations in cruise:∙SPD when VNAV engages∙SPD, VNAV is not actived) Descent (DES)i. These are the three autothrottle modes in descent:∙VNAV∙FLCH∙Autothrottle speed mode.ii. These are the autothrottle mode annunciations in descent:∙IDLE, THR, or HOLD shows for VNAV∙THR, or HOLD shows for FLCH∙SPD.e. Approach (APP)SPD is normal mode in approach with glideslope active or in a manual approach.i. Go-Around (GA)A GA mode request causes the autothrottle mode to change to THR. A second GArequest causes the autothrottle mode to change to THR REF. The TO/GA lever must be pushed to request GA.ii. Flare RetardFlare retard occurs when a specified altitude threshold has been achieved during approach with a command from the autopilot flight director system (AFDS). The autothrottle mode changes to IDLE during a flare retard.1.6E.3.2 Autothrottle DisconnectThe autothrottle disconnects when there is a manual autothrottle disconnect or when there is thrust reverser application. This occurs after initial touchdown during rollout.1.6E.4 Electrical PowerThe electrical system generates and distributes AC and DC power to other aircraft systems,and is comprised of: main AC power, backup power, DC power, standby power, and flightcontrols power. System operation is automatic. Electrical faults are automatically detectedand isolated. The AC electrical system is the main source for airplane electrical power.Figure 1.6EF shows the cockpit Electrical panel where electrical switching can be made. Italso shows the associated lights.1.6E.4.1 Electrical Load Management System (ELMS)The ELMS provides load management and protection to ensure power is available to criticaland essential equipment. If the electrical loads exceed the power available (aircraft or external), ELMS automatically sheds AC loads by priority until the loads are within thecapacity of the aircraft or ground power generators. The load shedding is non-essential equipment first, then utility busses. Utility busses are followed by individual equipment itemspowered by the main AC busses. When an additional power source becomes available orthe loads decrease, ELMS restores power to shed systems (in the reverse order). Themessage LOAD SHED displays on the electrical synoptic when load shed conditions exist.1.6E.4.2 AC Electrical System Power SourcesThe entire aircraft AC electrical load can be supplied by any two main AC power sources.The main AC electrical power sources are:∙left and right engine integrated drive generators (IDGs)∙APU generator∙primary and secondary external powerThe power sources normally operate isolated from one another. During power sourcetransfers on the ground (such as switching from the APU generator to an engine generator)operating sources are momentarily paralleled to prevent power interruption.1.6E.4.3 Integrated Drive Generators (IDGs)Each engine has an IDG. Each IDG has automatic control and system protection functions.When an engine starts, with the GENERATOR CONTROL switch selected ON, the IDG automatically powers the respective main bus. The previous power source is disconnectedfrom that bus.The IDG can be electrically disconnected from the busses by pushing the GENERATOR CONTROL switch to OFF. The IDG can also be electrically disconnected from its respective bus by selecting an available external power source prior toengine shutdown. The DRIVE light illuminates and the EICAS message ELEC GEN DRIVE Lor R displays when low oil pressure is detected in an IDG. The IDG drive can be disconnected from the engine by pushing the respective DRIVE DISCONNECT switch. TheIDG cannot be reconnected by the flight crew. High drive temperature causes the IDG to disconnect automatically.。
