Before You Begin

Before installing Python:

Make sure your computer is connected to the internet.
It is recommended that you have Administrator privileges.
Windows 10 or Windows 11 is recommended.

Step 1 – Go to the Python Website

First, open your web browser.

There, you will find the option to download the latest stable version of Python.

If you are using Windows, download the Python 3.13 (64-bit) installer.

Step 2 – Download the Installer

Click the Download button to start downloading the installer.

Once the download is complete, the installer file will be available in your Downloads folder.

Double-click the installer file to open it.

Step 3 – Select "Add Python to PATH"

Once the installer opens, you will see a very important option:

Add Python to PATH

Make sure to check this option.

Selecting this option allows you to use Python commands from any folder in Command Prompt or PowerShell.

If you skip this step, you will need to configure the PATH manually later.
