OS module in Python provides various methods for interacting with the operating system. It comes under Python’s standard utility module, so there is no need to install it externally. os.path is a submodule of OS module which contains some useful functions on pathnames. The path parameters are either strings or bytes. These functions here are used for different purposes such as for merging, normalizing and retrieving path names in Python.
According to docs
os.path.abspath() returns a normalized absolutized version of the pathname path which may sound fancy but it simply means that this method returns the pathname to the path passed as a parameter to this function.
Path: A path-like object representing a file system path.
Return Type: This method returns a normalized version of the pathname path.
Example 2: This function can also return the normalized path after changing the current working directory.
