How to Add Python to PATH

In this tutorial, you will learn how to add Python to the PATH environment variable on Windows, Linux, and macOS. Adding Python to PATH is necessary when you have installed Python but cannot run it from the command line. We will explore what PATH is, its importance, and how to manage it.

How to Add Python to PATH on Windows

  1. Locate the directory where your Python executable resides. The executable is usually named python.exe and could be in C:\Python\ or your AppData\ folder.
  2. Verify that the executable works by double-clicking on it and ensuring that it opens a Python REPL in a new window.
  3. If you cannot find the executable, use the search feature in Windows Explorer.
  4. Once you have located the Python executable, open the Start menu and search for “Edit the system environment variables” to open the System Properties window.
  5. In the Advanced tab, click on the “Environment Variables” button.
  6. In the User Variables section, double-click on the entry named “Path”.
  7. In the new window, click on the “New” button and paste the path to the Python executable.
  8. Click “OK” to save the changes.

How to Add Python to PATH on Linux and macOS

  1. Open a terminal.
  2. Run the following command to locate the Python executable: which python.
  3. The output will display the path to the Python executable.
  4. Edit your .bashrc or .bash_profile file using a text editor like nano or vim: nano ~https://codemdd.io/.bashrc or nano ~https://codemdd.io/.bash_profile.
  5. Add the following line at the end of the file, replacing https://codemdd.io/pathhttps://codemdd.io/tohttps://codemdd.io/python with the actual path to the Python executable: export PATH=https://codemdd.io/pathhttps://codemdd.io/tohttps://codemdd.io/python:$PATH.
  6. Save the file and exit the text editor.
  7. Run source ~https://codemdd.io/.bashrc or source ~https://codemdd.io/.bash_profile to apply the changes.
  8. Verify that Python has been added to PATH by running python or python3 in the terminal.

Understanding What PATH Is

  • PATH is an environment variable that contains a list of directories on your operating system.
  • It is used by the command line to search for executable scripts and programs.
  • When you run a command in the terminal, the system checks each directory in PATH to find the corresponding executable file.

Understanding the Importance of Order Within PATH

  • The order of directories in PATH matters because it determines the priority when searching for executables.
  • If multiple directories in PATH contain the same executable name, the system will use the one in the directory listed first in PATH.

Managing Your PATH on UNIX-based Systems

  • To view your current PATH, open a terminal and run the command echo $PATH.
  • To add a directory to PATH temporarily in the current terminal session, use the command export PATH=https://codemdd.io/pathhttps://codemdd.io/tohttps://codemdd.io/directory:$PATH.
  • To make a permanent change to PATH, edit the .bashrc or .bash_profile file and add the export PATH=https://codemdd.io/pathhttps://codemdd.io/tohttps://codemdd.io/directory:$PATH line.
  • After making changes to the file, run source ~https://codemdd.io/.bashrc or source ~https://codemdd.io/.bash_profile to apply the changes.

Conclusion

Adding Python to PATH is essential for running Python from the command line without any issues. In this tutorial, we covered how to add Python to PATH on Windows, Linux, and macOS. Understanding PATH and managing it correctly ensures that your system can find and use your Python installation effectively.
