Linux operating system :

1. There is a very good chance your Linux distribution has Python installed already, but it probably won’t be the latest version, and it may be Python 2 instead of Python 3. To find out what version(s) you have, open a terminal window and try the following commands :

python --version
python2 --version
python3 --version

2. If Python 2.7 or later is not installed, install Python with your distribution's package manager. The command and package name varies :

1. On Debian derivatives such as Ubuntu, use apt.
$ sudo apt-get install python3


2. On Red Hat and derivatives, use yum.
$ sudo yum install python3


3. On SUSE and derivatives, use zypper.
$ sudo zypper install python3

3. Open a command prompt or shell and run the following command to verify that Python installed correctly.

$ python3 --version

macOS / Mac OS X operating system :

While current versions of macOS (previously known as “Mac OS X”) include a version of Python 2, it is likely out of date but the best way we found to install Python 3 on macOS is through the Homebrew package manager. This approach is also recommended by community guides like The Hitchhiker’s Guide to Python.
