from msrest.authentication import CognitiveServicesCredentials

#TEXT_ANALYTICS_SUBSCRIPTION_KEY = 'b2c4f0ee35c941078d9e6971c15c3472'
#TEXT_ANALYTICS_ENDPOINT = 'https://westcentralus.api.cognitive.microsoft.com/text/analytics'

if not key_var_name in os.environ:
    raise Exception('Please set/export the environment variable: {}'.format(key_var_name))
subscription_key = os.environ[key_var_name]

endpoint_var_name = 'TEXT_ANALYTICS_ENDPOINT'
if not endpoint_var_name in os.environ:
    raise Exception('Please set/export the environment variable: {}'.format(endpoint_var_name))
endpoint = os.environ[endpoint_var_name]

def authenticateClient():
    credentials = CognitiveServicesCredentials(subscription_key)
    text_analytics_client = TextAnalyticsClient(
        endpoint=endpoint, credentials=credentials)
    return text_analytics_client

sentence = input("Enter the string:")

def sentiment():

    client = authenticateClient()

    try:
        documents = [
            {"id": "1", "language": "en", "text": sentence}
        ]

        response = client.sentiment(documents=documents)
        for document in response.documents:
            print("Entered Text: ", document.text, ", Sentiment Score: ",
                  "{:.2f}".format(document.score))

    except Exception as err:
        print("Encountered exception. {}".format(err))
sentiment()
