Hi, I'm new here. Help fix this python code.

I am working on a project to create a voice assistant using python 3.10 in pycharm. When the program starts, an error appears:

Traceback (most recent call last):
File "D:\alexa.p y", line 56, in <module>
query = takecommand().l ower()

            results = wikipedia.summary(query, sentences = 5)
            print(results)
            speak(results)

        elif 'открой почту' in query:
            webbrowser.open('mail.ru')

        elif 'время' in query :
            strtime = datetime.datetime.now().strftime('%H:%M:%S')
            speak(f'сейчас {strtime}')

        elif 'пайчарм' in query :
            codepath = 'C:\Program Files\JetBrains\PyCharm Community Edition 2021.3.2\bin\pycharm64'
            os.startfile(codepath)

        elif 'выход' in query:
            speak('хорошо, пожалуйста позовите меня если вам понадобиться моя помощь')
            quit()

I tried to fix the mistake, but nothing comes out. It's only clear to me that there is no default device available, but I still don't understand how to fix it, given that there is not only this error. Please help me complete this project.
