os.path.dirname

os.path.dirname() is a function in Python's built-in os module that returns the directory name of a given path.

For example, if we have a file path "/usr/local/bin/python", `os.path.dirname("/usr/local/bin/python")` would return "/usr/local/bin".

This function can be useful for extracting the directory path of a file or folder to perform operations on it, such as creating a new file in the same directory.
