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 submodule of OS module in Python used for common path name manipulation.
os.path.commonpath() method in Python is used to get the longest common sub-path in a list of paths. This method raise ValueError if the specified list of paths either contains both absolute and relative path, or is empty. Unlike
os.path.commonpath() method, the returned value is a valid path.
For example consider the following list of paths:
list of paths Longest common sub-path ['/home/User/Photos', /home/User/Videos'] /home/User ['/usr/local/bin', '/usr/lib'] /usr
path: A list of path-like object. A path-like object is either a string or bytes object representing a path.
Return Type: This method returns a string value which represents the longest common sub-path in the specified list.
Code #1: Use of os.path.commonpath() method
Longest common sub-path: /home/User Longest common sub-path: /usr
Code #2: Use of os.path.commonpath() method
Traceback (most recent call last): File "oscommonpath.py", line 12, in prefix = os.path.commonpath(paths) File "/usr/lib/python3.6/posixpath.py", line 505, in commonpath raise ValueError("Can't mix absolute and relative paths") from None ValueError: Can't mix absolute and relative paths
Note: If the specified list is empty,
os.path.commonpath() method will raise ValueError too.
