Install Python

Python is a programming language and also a program, that will execute the script. Open Terminal (Linux/macOS) or Command Prompt (Windows) and type python3 --version. If the output is something like Python 3.7.7, then Python is installed. Note that the script works on version 3 (3.x.x). If the output is something like command not found, then you should install Python from the official site: https://www.python.org/downloads/.

We'll also need pip, it's a "store" of Python programs. If you installed Python from the official site, it should be there already. You can check it via pip3 --version. If the output is command not found, then install pip as described on the official site: https://pip.pypa.io/en/stable/installing/.
