The os.path.join() Method

The os.path.join() method joins one or more path components intelligently, avoiding extra directory separator (os.sep) characters.

import os

path = os.getcwd()
directory = os.path.join(path, "__python_demo__")
print("path:", path)
print("directory:", directory)

Output:

path: /home/ubuntu/workspace
directory: /home/ubuntu/workspace/__python_demo__
