Installing
To install the Python interpreter on yourcomputer, follow these steps:

Run your system's package manager. (On Ubuntu orDebian, I recommend running Synaptic).Find the package for Python 3. On many systems (e.g. Ubuntu) thiswill be called 'python3'. Install it.
macOS
In a web browser, go to the Pythondownload page. Click the button "Download Python 3.10.1"(it may have a larger number if a newer version is available). Whenthe installer finishes downloading, run it, and accept all theinstallation defaults.

You'll now see a window "Install Python3.10.1(64-bit)". In this window, be sure to check the box "AddPython 3.10 to PATH". Now click "Install Now". You'llsee a message "Do you want to allow this app to make changes toyour device?" Click Yes.
