可爱的Python_模块篇

Python有趣的代码Python是一种简单易学、功能强大的编程语言，它不仅适用于开发各种类型的应用程序，还可以用来编写有趣的代码。

本文将为您介绍一些有趣的Python代码，希望能给您带来一些乐趣和启发。

1. 打印自己的名字name = "John Doe"print(f"Hello, my name is {name}")这段代码使用了Python的f-string格式化字符串功能，将变量name的值插入到字符串中，实现了打印自己的名字。

2. 猜数字游戏import randomnumber = random.randint(1, 100)guess = Nonewhile guess != number:guess = int(input("猜一个1到100之间的数字: "))if guess < number:print("太小了，再试试！")elif guess > number:print("太大了，再试试！")else:print("恭喜你，猜对了！")这段代码实现了一个简单的猜数字游戏。

程序会生成一个1到100之间的随机数，然后提示用户猜数字，根据用户的猜测给出提示，直到猜对为止。

3. 绘制彩色螺旋import turtlecolors = ["red", "orange", "yellow", "green", "blue", "purple"]turtle.speed(0)for i in range(360):turtle.pencolor(colors[i % len(colors)])turtle.width(i / 100 + 1)turtle.forward(i)turtle.left(59)这段代码利用Python的turtle模块绘制了一个彩色螺旋。

python创意小作品代码以下是一个简单的Python创意小作品代码示例：```pythonimport turtle#设置画布和画笔canvas=turtle.Screen() canvas.title("Python创意小作品") canvas.bgcolor("white")pen=turtle.Turtle()pen.speed(0)pen.width(3)#绘制彩虹colors=["red","orange","yellow","green","blue","purple"] radius=100for color in colors:pen.pencolor(color)pen.circle(radius)radius+=10#绘制心形pen.up()pen.goto(0,-150)pen.down()pen.pencolor("red")pen.begin_fill()pen.left(140)pen.forward(224)for i in range(200):pen.right(1)pen.forward(2)pen.left(120)for i in range(200):pen.right(1)pen.forward(2)pen.forward(224)pen.end_fill()#隐藏画笔pen.hideturtle()#关闭画布turtle.done()```这个小作品使用了Python的turtle库来绘制彩虹和心形图案。

运行这段代码后，会打开一个画布窗口，窗口背景为白色。

画笔会按照红、橙、黄、绿、蓝、紫的顺序绘制彩虹，然后绘制一个红色的心形图案。

你可以根据自己的创意，修改代码来绘制其他图案或者添加其他功能。
