参数, 解包, 变量

• 输入：

# -- coding: utf-8 --

from sys import argv
# import 语句，这是将 Python 的功能模块加入你自己脚本的方法

script, first, second, third = argv
# 将参数变量“argv”解包

print "The script is called:", script
print "Your first variable is:", first
print "Your second variable is:", second
print "Your third variable is:", third

• 运行：

  
  

在cmd输入打开这个py文件的同时，要输入3个参数才能正常运行

附加题

• 将 raw_input 和 argv 一起使用

from sys import argv

script, a, b = argv

print "The script is called:", script
print "The first variable is:", a
print "The second variable is:", b

y=raw_input("Please input your name\n>")
print "Hello, my name is %s." % y
