Python脚本运行问题，在pycharm中运行会出错

Question

初学python,写了一段脚本：
from sys import argv
script,user_name=argv
prompt='<'
print("hi %s,i am the %s script."%(user_name,script))
print("I'd like to ask you a few questions.")
print("DO you like me %s"%user_name)
input(prompt)

在Pycharm上面运行会出现如下错误：
D:\PycharmProjects\untitled\venv\Scripts\python.exe D:/PycharmProjects/untitled/ex14.py
Traceback (most recent call last):
File "D:/PycharmProjects/untitled/ex14.py", line 2, in
script,user_name=argv
ValueError: not enough values to unpack (expected 2, got 1)

Process finished with exit code 1

这是什么原因，用cmd运行就没有问题，可以出来结果

Answer 1

from sys import argv
script=argv
user_name=argv
prompt='<'
print("hi %s,i am the %s script."%(user_name,script))
print("I'd like to ask you a few questions.")
print("DO you like me %s"%user_name)
input(prompt)

分开写就可以了
