python——我遇到了 UnboundLocalError 的问题：在分配之前引用了局部变量“命令”[重复]

关于我的问题，我见过类似的问题，但它们似乎没有帮助。

我的密码是

def take_command(): 
    try:
        with sr.Microphone() as source:
            print('listening...')
            voice = listener.listen(source)
            command = listener.recognize_google(voice)
            command = command.lower()
            if 'give' in command:
                print('give mentioned')
                comand = command.replace('give' '')
                print(comand)
    except:
        pass
    return command


def run_give():
    command = take_command()
    print(command)

错误是

Traceback (most recent call last):
  File "c:\Users\REDACTED\REDACTED\REDACTED\REDACTED\main.py", line 72, in 
    run_give()
  File "c:\Users\REDACTED\REDACTED\REDACTED\REDACTED\main.py", line 38, in run_give
    command = take_command()
  File "c:\Users\REDACTED\REDACTED\REDACTED\REDACTED\main.py", line 34, in take_command
    return command
UnboundLocalError: local variable 'command' referenced before assignment

我尝试了很多方法来修复它，但都没有效果。
