How to Add Python to PATH

In this tutorial, you will learn how to add Python to PATH, which is an important step to ensure that your Python installation is recognized by the command line and other programs. We will cover the steps for Windows, Linux, and macOS operating systems.

How to Add Python to PATH on Windows

  1. Locate the directory where your Python executable is installed. The path to this directory is what you will be adding to the PATH environment variable.

  2. Look for a file called python.exe within the directory. This file is the Python executable that you need to add to PATH.

  3. To check if the executable works, double-click it and see if it opens a Python REPL in a new window.

  4. If you are having trouble finding the executable, you can use the search feature in Windows Explorer. Alternatively, you can use a powerful file search tool like “Everything” for a faster and more comprehensive search.

  5. Once you have located the Python executable, open the Start menu and search for “Edit the system environment variables” and open it. This will open the System Properties window.

  6. In the System Properties window, go to the Advanced tab and click on the “Environment Variables” button.

  7. In the Environment Variables window, you will see User variables and System variables. For this tutorial, we will be editing the User variables.

  8. Scroll down in the User variables section until you find the entry named “Path” and double-click it.

  9. In the Edit Environment Variable window, click on the “New” button and paste the path to the directory where your Python executable is located.

  10. Click “OK” to save the changes and close all the windows.

  11. To verify that Python has been added to PATH, open a new command prompt window and type python. If Python starts up without any errors, then you have successfully added Python to PATH.

How to Add Python to PATH on Linux and macOS

  1. Launch a terminal window.

  2. In the terminal, type the following command to open your shell’s configuration file:

    Terminal window
    nano ~https://codemdd.io/.bashrc

    This command will open the .bashrc file in the nano text editor.

  3. Scroll to the end of the file and add the following line:

    Terminal window
    export PATH="https://codemdd.io/usrhttps://codemdd.io/localhttps://codemdd.io/binhttps://codemdd.io/python:$PATH"

    Replace https://codemdd.io/usrhttps://codemdd.io/localhttps://codemdd.io/binhttps://codemdd.io/python with the path to your Python executable.

  4. Press Ctrl + X to exit nano, and then press Y to save the changes.

  5. To apply the changes, run the following command in the terminal:

    Terminal window
    source ~https://codemdd.io/.bashrc

  6. To verify that Python has been added to PATH, open a new terminal window and type python. If Python starts up without any errors, then you have successfully added Python to PATH.

Understanding What PATH Is

The PATH environment variable is a list of directories that your operating system uses to find executable scripts and programs. When you run a command in the command prompt or terminal, the operating system checks each directory in the PATH to see if it contains the executable file for that command.

By adding Python to PATH, you allow the command prompt or terminal to find the Python executable without specifying the full path to it every time.

Understanding the Importance of Order Within PATH

The order of directories in the PATH variable is crucial because the operating system checks them in order from left to right. If you have multiple installations of Python or other programs with the same executable names, the order determines which one will be executed.

Managing Your PATH on UNIX-based Systems

On UNIX-based systems like Linux and macOS, you can manage your PATH by editing the .bashrc file, as demonstrated in the previous section. This file is loaded every time you open a new terminal window, and any changes you make to the PATH in this file will be applied to your terminal sessions.

Conclusion

Adding Python to the PATH environment variable is an essential step in ensuring that your Python installation is recognized by the command line and other programs. By following the steps outlined in this tutorial, you should be able to add Python to PATH on various operating systems.

Remember to verify that Python has been added to PATH by opening a new command prompt or terminal window and typing python. If Python starts without any errors, then you have successfully added it to PATH.

Congratulations! You can now use Python seamlessly with the command line and other programs on your computer. Happy coding!
