笨办法学Python3 习题13 参数 解包 变量

1 from sys import argv                      # 把 系统模块 导入 参数变量 ,必须写argv
2 
3 script, first, second, third = argv       # 把 argv 参数变量解包(argv字母不能改)，依次赋值给四个变量,四个变量名可任意
4 
5 print("The script is called:",script)     # 这个脚本被调用，ex13.py
6 print("Your first variable is:",first)    # 你的第一个变量是XX
7 print("Your second variable is:",second)  # 你的第二个变量是XX
8 print("Your third variable is:",third)    # 你的第三个变量是XX

PS C:\Users\Administrator\lpthw> python ex13.py apple orange banana
The script is called: ex13.py
Your first variable is: apple
Your second variable is: orange
Your third variable is: banana
