StopIteration error in python
Question: I am using `wolframalpha` and `wit.ai` together and i am trying to build that
`wolframalpha` fetch data from `wit.ai` audio instead of terminal text.

My code is:

    
    
    #!/usr/bin/python
    import speech_recognition as sr
    import wolframalpha
    import sys
    
    r = sr.Recognizer()
    with sr.Microphone() as source:
        print("Say something!")
        audio = r.listen(source)
    
    
    WIT_AI_KEY = "NQYEITRO5GL2Q2MZFIJE4UHWVNQEUROW"
    try:
        print("Wit.ai thinks you said " + r.recognize_wit(audio, key=WIT_AI_KEY))
    except sr.UnknownValueError:
        print("Wit.ai could not understand audio")
    except sr.RequestError as e:
        print("Could not request results from Wit.ai service; {0}".format(e))
    
    
    client = wolframalpha.Client('PR5756-H3EP749GGH')
    print(r.recognize_wit(audio, key=WIT_AI_KEY))
    res = client.query(r.recognize_wit(audio, key=WIT_AI_KEY))
    print(next(res.results).text)
    

I am facing this error:

        print(next(res.results).text)
    StopIteration
    

How can I give data to wolframalpha api?


Answer: `StopIteration` is raised when generator is exhausted and has no more values,
it's totaly ok to get one. But you need to handle it yourself:

    
    
    try:
        print(next(res.results).text)
    except StopIteration:
        print("No more suggesstions.")
