If you mean Python 2, it will still be supported until 2020 (and that's assuming they don't push back EOL again, which I hope they don't). If you mean the libraries won't be supported, that's just not true. Most of the google api client libraries are Py2 only, for example, and are regularly updated. I recommend Python 3 to everyone, and it's my first choice over Py2 for both personal and commercial stuff. Most of the time everything will work A-OK, or better. But sometimes you still have to use Python 2.
