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
