UnboundLocalError: local variable 'result' referenced before assignment

[christiannnc]

This is my chatbot.py file, copied from the YouTube video. It yields an UnboundLocalError response that says the variable 'result' is referenced before it is assigned.

os.environ['TF_CPP_MIN_LOG_LEVEL'] = '2'

def clean_up_sentence(sentence):

    error_threshold = 0.2
    results = [[i, r] for i, r in enumerate(res) if r > error_threshold]

    results.sort(key=lambda x: x[1], reverse=True)
    return_list = []

    res = get_response(ints, intents)
    print(res)
