新人想学自动化，刚学习简单的python遇到了问题

from sys import argv

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)

运行后C:\Users\Administrator\AppData\Local\Programs\Python\Python36\python.exe D:/python/笨方法学python/case13.py
Traceback (most recent call last):
File "D:/python/笨方法学python/case13.py", line 3, in <module>
    script, first, second, third = argv
ValueError: not enough values to unpack (expected 4, got 1)


上网百度过 说要在命令行 运行pythoncase13.py arg 1 arg2 arg 3
但是返回报错找不到文件

你安装的是python2,还是3？
把script, first, second, third = argv
改成script, first, second, third = argv，argv,argv,argv 试一下呢
