Python os.path.basename() method is the most efficient way of finding the basename of a specified path. This method uses the os.path.split() method to first split the path address into a pair of head and tail, then display the tail part.

Syntax of Python os.path.basename() Method

os.path.basename(path) 

Parameters

Return

This method’s return type is a path string containing the file’s absolute address.

Example 1: Use the os.path.basename() Method in Python

import os  path = "/home///user/Documents"  normalize = os.path.basename(path)  print(normalize)  path = "/home/./Desktop"  normalize = os.path.basename(path)  print(normalize) 

Output:

Documents Desktop 

The os.path.basename() is a simple method to interact with the operating system and retrieve the base name of any specific file.

Example 2: Extract a File Name Using the os.path.basename() Method

import os  path = "/home/user/temp/../Downloads/File.txt"  normalize = os.path.basename(path)  print(normalize) 

Output:

File.txt 

Note that the os.path.basename result is not similar to the value returned from the Unix basename program.

Example 3: Use os.path.dirname() With the os.path.basename() Method

import os  path = "home/user/File.txt"  head = os.path.dirname(path)  tail = os.path.basename(path)  rejoin = head + tail  print("The head of the path '%s': " % path, head)  print("The tail of the path '%s': " % path, tail)  print("The full path address is: ", rejoin) 

Output:

The head of the path 'home/user/File.txt': home/user The tail of the path 'home/user/File.txt': File.txt The full path address is: home/userFile.txt 

If we use the os.path.split() method to split the path, then the head part is the same value returned by the os.path.dirname.

Example 4: Set Path Address as Empty in the os.path.basename() Method

import os  address = ""  directory = os.path.basename(address)  print(directory) 

Output:

The os.path.basename() doesn’t return anything as no path address is specified.
