main()

这是我的终端

Traceback (most recent call last):

    main()
  File "c:\Users\PC\Documents\Code\assistant\Jarvis.py", line 86, in main
    with open ("Jarvis.txt", "a") as Jarvis:
UnboundLocalError: local variable 'open' referenced before assignment

感谢您的帮助

这是因为您已经将 open 命令定义为一个变量，它是主要的 Python 命令之一。

此时，您似乎将此字符串放入和并尝试使用该字符串打开文件，这会导致错误。

open = "C:\Program Files (x86)\BraveSoftware\Brave-Browser\Application\Brave.exe"

将您在第 146 行定义的开放变量重命名为另一个名称，如 open_ 以解决您的问题。
