This quick tutorial is going to show you how to install the latest Python 3.6.1 in Ubuntu 16.04 LTS via PPA.

Ubuntu 16.04 comes with both Python 2.7 and Python 3.5 by default. You can install Python 3.6 along with them via a third-party PPA by doing following steps:

1. Open terminal via Ctrl+Alt+T or searching for “Terminal” from app launcher. When it opens, run command to add the PPA:

sudo add-apt-repository ppa:jonathonf/python-3.6

Type in your password (no visual feedback due to security reason) when it asks and hit Enter.

2. Then check updates and install Python 3.6 via commands:

sudo apt-get update

sudo apt-get install python3.6

Now you have three Python versions, use python command for version 2.7, python3 for version 3.5, and/or python3.6 for version 3.6.1.

3. To make python3 use the new installed python 3.6 instead of the default 3.5 release, run following 2 commands:

sudo update-alternatives --install /usr/bin/python3 python3 /usr/bin/python3.5 1

sudo update-alternatives --install /usr/bin/python3 python3 /usr/bin/python3.6 2

Finally switch between the two python versions for python3 via command:

sudo update-alternatives --config python3

After selecting version 3.6:

python3 -V
