Python2的argv代码
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)

Answer 1

“script, first, second, third = argv”参数个数不正确。argv应该等于4个，你可能大于或小于四个，或者你没有参数传入导致argv为空也就是None。
