Obtaining and installing Python

Installation of Python is fast on Linux and Windows platforms. Windows users can use an installer in an easy way that makes configuration work for you. In Linux, you have the option to build the installation from the source code, but it's not mandatory, and you can use classic package-management dependencies, such as apt-get.

Many Linux distributions come preinstalled with Python 2. When installing Python 3 on such a system, it is important to keep in mind that we are not replacing the installation of Python 2. In this way, when we install Python 3, it can be installed in parallel with Python 2 on the same machine. After installing Python 3, you can call the python interpreter using the Python3 executable.
