如何使用ios pythonista 3进行此练习？

Question

我对python很陌生，我是通过阅读一本书来学习的(用艰苦的方法学习Python 3)。书中有一个练习(Exercise14)不能使用iOS Pythonista 3运行。

该脚本如下：

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.
     """)

但后来我发现了一个错误：

  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，我是新来的。

谢谢你们！

如果您长时间按下Pythonista上的run ("play")按钮，您可以添加脚本所期望的命令行参数(用户名，默认情况下得到的脚本名称)。
