程序交互

读取用户输入

下面为读取用户输入信息代码

name = input("What is your name?")
age = input("How old are you?")
hometown = input("Where is your hometown?")
print("Hello ",name , "your are ", age , "years old, you came from",hometown)

下面为以上代码的执行结果

What is your name?houxingbin
How old are you?18
Where is your hometown?binzhou
Hello  houxingbin your are  18 years old, you came from binzhou

注意，input输入的默认为字符类型，如果需要整型则需要进行转换，如：

age = int(input("How old are you?"))

 

注释

为了程序的便于维护，想必注释是必不可少的

代码注释原则:

1. 不用全部加注释，只需要在自己觉得重要或不好理解的部分加注释即可
2. 注释可以用中文或英文，但绝对不要拼音噢
