Python | os.path.normpath() method

OS module in Python provides functions for interacting with the operating system. OS comes under Python’s standard utility modules. This module provides a portable way of using operating system dependent functionality. os.path module is sub module of OS module in Python used for common path name manipulation.

os.path.normpath() method in Python is used to normalize the specified path. All redundant separator and up-level references are collapsed in the process of path normalization.
For example: A//B, A/B/, A/./B and A/foo/../B all will be normalized to A/B.
On Windows operating system, any forward slash (‘/’) in the path is converted to backslash (‘\’).

Syntax: os.path.normpath(path)



Parameter:
path: A path-like object representing a file system path.

Return Type: This method returns a string value which represents the normalized path.
