Python | os.path.basename() 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.basename() method in Python is used to get the base name in specified path. This method internally use os.path.split() method to split the specified path into a pair (head, tail). os.path.basename() method returns the tail part after splitting the specified path into (head, tail) pair. 

Syntax: os.path.basename(path)
Parameter:
path: A path-like object representing a file system path. 
Return Type: This method returns a string value which represents the base name the specified path. 

Code: Use of os.path.basename() method 

Python3

# Python program to explain os.path.basename() method

# importing os.path module
import os.path

# Path
path = '/home/User/Documents'


# Above specified path
# will be splitted into
# (head, tail) pair as
# ('/home/User', 'Documents')

# Get the base name
# of the specified path
basename = os.path.basename(path)

# Print the base name
print(basename)


# Path
path = '/home/User/Documents/file.txt'

# Above specified path
# will be splitted into
# (head, tail) pair as
# ('/home/User/Documents', 'file.txt')

# Get the base name
# of the specified path
basename = os.path.basename(path)

# Print the basename name
print(basename)


# Path
path = 'file.txt'


# The above specified path
# will be splitted into
# head and tail pair
# as ('', 'file.txt')
# so 'file.txt' will be printed

# Get the base name
# of the specified path
basename = os.path.basename(path)

# Print the base name
print(basename)

Output:

Documents
file.txt
file.txt
