Adding python to path on windows

When working with Python on Windows, it is important to have Python added to the system’s PATH variable. This allows you to run Python scripts from any directory without having to specify the full path to the Python executable. In this article, we will explore three different ways to add Python to the PATH on Windows.

Option 1: Manual Configuration

The first option is to manually configure the PATH variable by adding the Python installation directory to it. Here are the steps to follow:

  1. Open the Start menu and search for “Environment Variables”.
  2. Click on “Edit the system environment variables”.
  3. In the System Properties window, click on the “Environment Variables” button.
  4. In the “System variables” section, scroll down and select the “Path” variable.
  5. Click on the “Edit” button.
  6. In the Edit Environment Variable window, click on the “New” button.
  7. Enter the path to the Python installation directory (e.g., C:Python39) and click “OK”.
  8. Click “OK” in all the open windows to save the changes.

Option 2: Using the Python Launcher

The second option is to use the Python Launcher for Windows, which is included with Python starting from version 3.3. The Python Launcher allows you to specify the version of Python you want to use when running a script. To add Python to the PATH using the Python Launcher, follow these steps:

  1. Open the Start menu and search for “Python Launcher”.
  2. Click on “Python Launcher (Command Line)”.
  3. In the Python Launcher window, click on the “Options” button.
  4. Select “Register Python in environment variables” and click “OK”.

Option 3: Using an Installer

The third option is to use an installer that automatically adds Python to the PATH for you. One popular installer is Anaconda, which is a distribution of Python that comes with many scientific packages pre-installed. To add Python to the PATH using Anaconda, follow these steps:

  1. Download the Anaconda installer from the official website.
  2. Run the installer and follow the instructions.
  3. During the installation process, make sure to select the option to add Anaconda to the system PATH.

After considering the three options, the best approach depends on your specific needs. If you prefer a manual configuration and have a basic Python installation, Option 1 is a good choice. If you want more flexibility in choosing the Python version, Option 2 with the Python Launcher is recommended. Finally, if you require a comprehensive Python distribution with pre-installed packages, Option 3 with Anaconda is the way to go.
