Googletrans is a free and unlimited python library that implemented Google Translate API. This uses the Google Translate Ajax API to make calls to such methods as detect and translate.
You can install it from PyPI :
$ pip install googletrans HTTP/2 support ¶ This is a great deal for everyone! (up to 2x times faster in my test) If you want to get googletrans faster you should install hyper package. Googletrans will automatically detect if hyper is installed and if so, it will be used for http networking.
