导入自定义函数时出错

Question

When I try to import a function from a file, it doesn't recognize the module that I imported earlier, while when its defined directly then there is no problem.

The module is imported as sr. Should I import it body of the function or is there any other trick.

    # doesn't work
    import speech_recognition as sr
    r = sr.Recognizer()

    from Chatfunctions import Listner



    Listner()

NameError: name 'sr' is not defined


    # works
    import speech_recognition as sr
    r = sr.Recognizer()


    def Listner():
        with sr.Microphone() as source:
            print("...")
            audio=r.listen(source)

          try:
            print("You: "+r.recognize_google(audio));
            return r.recognize_google(audio)
          except:
            pass;
    Listner()

导入函数中使用的所有模块都需要导入到定义函数的文件中
