关于script,first,second,third=argv运行出错的问题

from sys import argv

input(argv)

#python自带的IDLE直接执行不能提供命令行参数
script,first,second,third=argv

print("The script is called:",script)

print("Your first variable is :",first)

print("Your second variable is :",second)

print("Your  third variable is :",third)

在IDE中运行该代码块报：

Traceback (most recent call last):
  File "D:/ProgramFiles/Python33/workspace/var.py", line 6, in <module>
    script,first,second,third=argv
ValueError: need more than 1 value to unpack

错误，IDE中无法输入命令行参数，所以运行该代码块使用命令行运行，并输入命令行参数
