How to Convert Text from One Language to another using Microsoft's Translate API in Python?

I was trying to develop a Multi language Chat application which can convert text from one language to another using Python.

I have tried a couple of solutions and I found the Microsoft Bing Translate API to be a perfect solution for my requirement.

How to use that API in Python?

from translate import Translator

class clsTranslate():

    def translateText(self, strString, strTolang):
        self.strString = strString
        self.strTolang = strTolang
        translator = Translator(to_lang=self.strTolang)
        translation = translator.translate(self.strString)
        return (str(translation))

# Create a Class object and call the Translate function

objTrans=clsTranslate()
strTranslatedText= objTrans.translateText('How are you', 'de')

print(strTranslatedText)
