This will result in a system which mixes Debian releases, and will affect more than Python - in most cases, applying these instructions will pull in newer libraries too. Warning: this answer shows how to install Python from future releases of Debian. Press to keep the current choice, or type selection number: * 0 /usr/local/bin/python3.7 50 auto modeģ /usr/local/bin/python3.7 50 manual mode Sample output: There are 3 choices for the alternative python (providing /usr/bin/python). To switch between them, use: update-alternatives -config python The python3.7 with the 50 priority is now your default python, the python -V will print: Python 3.7.0b2 Update-alternatives -install /usr/bin/python python /usr/bin/python3.5 30 Update-alternatives -install /usr/bin/python python /usr/bin/python2.7 40 e,g: /usr/local/bin/python3.7Īdd the python versions: update-alternatives -install /usr/bin/python python /usr/local/bin/python3.7 50 Let's say you have installed the python3.7 on debian stretch, use the command whereis python to locate the binary ( */bin/python). To set a default python version and easily switch between them, you need to update your update-alternatives with the multiple python version. You can download the latest python-x.y.z.tar.gz from here.

Warning: make install can overwrite or masquerade the python binary. If you want pip to be included, you need to add -with-ensurepip=install to your configure call. It is recommended to use make altinstall according to the official website. configure -enable-optimizations -enable-shared
You can install Python-3.6 on Debian 8 as follows: wget
