小白一名，刚开始学习python,关于argv无反应,求大神帮帮忙！

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)

在PowerShell运行，并输入三个参数后，没有任何反应，如果多数参数或者少输参数都会有反应，求大神帮我看看是怎么一回事，谢谢您们~。
