以下是一些常见的Python基础代码：
1. 输出Hello World：
```python
print("Hello World")
```
2. 声明变量：
```python
age = 25
name = "John"
```
3. 输入和输出：
```python
name = input("What is your name?")
print("Nice to meet you, "+ name)
```
4. 条件语句：
```python
if age < 18:
print("You are too young to vote")
elif age >=18 and age < 21:
print("You can vote but cannot drink")
else:
print("You can vote and drink")
```
5. 循环语句：
```python
for i in range(1, 11):
print(i)
while n < 10:
print(n)
n += 1
```
6. 列表操作：
```python
my_list = ["apple", "banana", "cherry"]
my_list.append("orange")
my_list.remove("banana")
print(my_list)
```
7. 字典操作：
```python
my_dict = {"name": "John", "age": 25}
my_dict["gender"] = "male"
del my_dict["age"]
print(my_dict)
```
8. 函数：
```python
def add(a, b):
return a + b
sum = add(2, 3)
print(sum)
```
9. 类：
```python
class Person:
def __init__(self, name, age):
= name
self.age = age
def greeting(self):
print("Hello, my name is "+ )
person1 = Person("John", 25)
person1.greeting()
```
以上只是一些简单的Python基础代码，更多复杂的代码可以在学习过程中逐渐掌握。
