Editing Installing Python

== Installation ==

=== Linux and MacOS ===
On Linux and MacOS systems, Python should already be installed.

You can verify this using the method in the ''''Checking installation'''<nowiki/>' chapter.

If installed, you can skip to the ''''Project setup'''<nowiki/>' chapter.

=== Installing on Linux ===
If not installed, simply use your package manager to install ''''python3'.'''

==== Arch ====
On Arch-based distros (e.g. Manjaro), run the following command:
 sudo pacman -Sy python3

==== Debian ====
On Debian-based distros (such as Ubuntu), type:
 sudo apt install python3

=== Installing on Windows ===
On Windows, navigate to the [https://python.org/download/windows Python website] (python.org) and install the latest stable build.

Scroll to the bottom of this page and find '<nowiki/>'''Windows installer (64-bit)''''.

Open the .exe file and go through the installation process.

'''Note''': Make sure to 'add Python to system PATH'. This allows us to use Python through the terminal.

== Checking installation ==

=== Terminal setup ===
Once you have installed Python, open a system terminal.

On Linux and MacOS, this is called the ''''terminal'''<nowiki/>'.

On Windows, this is called the '<nowiki/>'''command prompt'''<nowiki/>' or ''''powershell'''<nowiki/>'.

=== Checking Python version ===
Now we need to run a command to check if Python is installed.

The result should be the name of the Python version you installed, printed to the screen.

==== Linux or MacOS ====
On Linux or MacOS, type the following command to check if Python is installed:
 python3 --version

==== Windows ====
On Windows, type this command into the command prompt:
 py --version

==== Checking Python install ====
If this returns a Python version, such as below, you have successfully installed Python:
 > '''python3 --version'''
   ''Python 3.11.3''
However, if this returns an error, like below, try reinstalling Python:
 '''> python3 --version'''
   ''zsh: command not found: python3''
