How To Add Python To Path

In this article we will show you the solution of how to add python to path, the PATH environment variable may need to be added to Python if you've installed Python, but typing python doesn't work.

It's possible to get an error message that says Python isn't recognized, or you may have the wrong Python version installed.

Python can be added to the PATH environment variable to resolve these problems. Here is a tutorial that shows you how to add Python to your PATH environment variable.

Furthermore, you will learn what PATH is, and why it is important for programs such as the command line to be able to locate your Python installation with the help of PATH.

We will now discuss the idea of how to add python to path in python with an example.

Step By Step Guide On How To Add Python To Path :-

import sys
import os
print(str(sys.path))
dir_path = os.path.dirname(os.path.realpath(__file__))
print(f"current working dir: {dir_path}")
root_dir = dir_path.replace("/util", '', 1)
print(f"root dir: {root_dir}")
sys.path.insert(0, root_dir)
print(str(sys.path))
  1. The first line imports two Python modules: sys and os.
  2. The second line prints the current list of directories in the sys.path variable, which is a list of directories where Python looks for modules to import.
  3. The third line sets the dir_path variable to the full path of the directory where the script is located. To get the full path, the os.path.realpath() function is used to get the absolute path to the file and the os.path.dirname() function is used to get the directory name from that path.
  4. The fourth line prints the dir_path variable.
  5. The fifth line sets the root_dir variable to the parent directory of dir_path. This is done by using the replace() method to remove the "util" directory from the dir_path variable.
  6. The sixth line prints the root_dir variable.
  7. The seventh line inserts the root_dir variable at the beginning of the sys.path list. This ensures that Python will check this directory first when looking for modules to import.
  8. The eighth line prints the updated sys.path list with the root_dir variable at the beginning.

Conclusion :-

As a result, we have successfully learned how to add python to path in python with an example.

The Python command line tool needs to be added to the Windows path before it can be run from the command line.

In addition to adding Python to the Windows path, there are several other techniques that can be used.

I hope this article on how to add python to path helps you and the steps and method mentioned above are easy to follow and implement.
