如何使用 ios pythonista 3 做这个练习？

Question

我是 python 的新手，我正在通过阅读一本书来学习它（学习 Python 3 很难）。 书中有一个练习（exercise14）不能使用iOS Pythonista 3运行。

脚本如下：

from sys import argv

script, user_name = argv
prompt = '> '

print(f"Hi {user_name}, I'm the {script} script.")

print("I'd like to ask you a few questions.")

print(f"Do you like me {user_name}?")

likes = input(prompt)

print(f"Where do you live {user_name}?")

lives = input(prompt)

print("What kind of computer do you have?")

computer = input(prompt)

print(f"""
    Alright, so you said {likes} about liking me.
    You live in {lives}.  Not sure where that is.
     And you have a {computer} computer.  Nice.
     """)

但后来我得到一个错误：

  File "/private/var/mobile/Containers/Shared/AppGroup/726BC931-58AE-44A6-9BE5-067EF23667A4/Pythonista3/Documents/Untitled.py", line 2, in <module>
    script, user_name = argv
ValueError: not enough values to unpack (expected 2, got 1)

请帮我解决这个问题，我很新。

感谢你们！

如果你长按 Pythonista 上的运行（“播放”）按钮，你可以添加你的脚本所期望的命令行参数（用户名，它默认获得的脚本名）。
