1.9 读取用户指令

若你的程序要接收用户指令，可以用input语法：

name = input("What is your name?")
print("Hello " + name )

执行脚本就会发现，程序会等待你输入姓名后再往下继续走。

可以让用户输入多个信息，如下

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)

结果输出

What is your name?Alex Li
How old are you?22
Where is your hometown?ShanDong
Hello  Alex Li your are  22 years old, you came from ShanDong

注意，input()方法接收的只是字符串，即使你输入的是数字，它也会按字符串处理
