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  python  case13.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
