Python
Python is an interpreted, high-level, general-purpose programming language.
Many of the tools like Ansible, Google Cloud SDK and AWS CLI are developed with and depend on Python.
Setup on macOS
The macOS setup will automatically install Ansible and Python 3 using Homebrew.
To install Python and pyenv, run the setup script with the python and pyenv
tags:
./setup -t python,pyenv
Setup on Linux
To install Python and pyenv, run the setup script with the python and pyenv tags:
./setup -t python,pyenv
Managing Python versions with pyenv
Both Linux and macOS configuration use the markosamuli.pyenv Ansible role for installing pyenv and the latest Python 2 and Python 3 versions.
After the setup is complete, you should see the following versions installed:
$ pyenv versions
system
* 2.7.16 (set by /home/markosamuli/.pyenv/version)
* 3.7.3 (set by /home/markosamuli/.pyenv/version)
Python 3 vs. Python 2
The use of Python 3 is highly preferred over Python 2 as the core Open Source Python 2.7 version will not be maintained past January 2020.
