EX Installation

🐍 Guide for Python Installation

Step 1: Download and Install Python

  1. Go to the Python download page
    Visit the official Python website.

  2. Download the appropriate installer
    Choose the correct version for your operating system:
    • Windows: .exe installer (64-bit recommended)
    • macOS: .pkg installer
    • Linux: Python is often pre-installed. If not, install it via your package manager (apt, dnf, yum, etc.).
  3. Start the installation
    • Run the downloaded installer.
    • Important: Check the box “Add Python to PATH”.
    • Click “Install Now” or choose “Customize Installation” if you want to adjust specific options.
  4. Verify the installation
    Open a terminal or command prompt and enter: 
    python --version

    or, on some systems:

    python3 --version

    You should see output like Python 3.12.6.
    If it doesn’t work, restart your computer and ensure Python is added to your system PATH.

Step 2: Check the Python Path

To confirm which Python version your system is using and where it’s installed, follow these steps:

🔹 Windows

  1. Open Command Prompt or PowerShell
    (Press Win + R, type cmd or powershell, and press Enter).
  2. Enter the command: 
    where python
  3. You’ll see one or more paths, for example: 
    C:\Users\YourName\AppData\Local\Programs\Python\Python311\python.exe
C:\Program Files\Python39\python.exe

    The first path listed is the default Python interpreter your system uses.

🔹 macOS / Linux

  1. Open the Terminal.
  2. Enter one of the following commands: 
    which python
# or, on newer systems:
which python3
  3. Example output: 
    /usr/bin/python3
/opt/homebrew/bin/python3

    The displayed path shows the active Python interpreter on your system.

✅ Tip:
To start Python interactively, type:

python
# or
python3

and press Enter.
To exit again, type:

exit()
