Path variables are configured to contain the location of executable files for running commands. When we run a command in the command prompt, it notes the name of the command and tries to find the executable file in its path.
We can run different commands from the command prompt from Python. This is because the path variable for Python is also configured when it is installed. At times, however, we might want to add a new directory to the
Path for maybe a new project to run this project directly from the command prompt.
In this tutorial, we will learn how to change or add PythonPath in windows.
Use the system settings to add or edit Python Path
In this method, we navigate to
My Computer and select
Properties. From there, we go to
Advanced System Settings and select
Environment Variables. From here, you can add the required directory to the Path of the already specified Python variable or create a new variable, assign its name as PythonPath and then mention the required full path. See the image below for more help.
Use the command line method to add or edit Python Path
We can run the below command in the command prompt to achieve this.
To set the PYTHONPATH permanently, add the line to your
Note that before using this method, run
If this gives you a path, proceed with this method; otherwise, do e.g.
If you don’t, windows will expand
%PYTHONPATH% to an empty string as expected, it will keep it as
%PYTHONPATH% in the
PYTHONPATH, and everything will break.
