Python | os.path.isabs() 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.isabs() method in Python is used to check whether the specified path is an absolute path or not.

On Unix platforms, an absolute path begins with a forward slash (‘/’) and on Windows it begins with a backward slash (‘\’) after removing any potential drive letter.

Syntax: os.path.isabs(path)

Parameter:
path: A path-like object representing a file system path.
A path-like object is either a string or bytes object representing a path.

Return Type: This method returns a Boolean value of class bool. This method returns True if specified path is an absolute path, otherwise returns False.

Code #1: Use of os.path.isabs() method (On Unix platforms)

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

# importing os.path module
import os.path

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

# Check whether the
# specified path is an
# absolute path or not
isabs = os.path.isabs(path)
print(isabs)


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

# Check whether the
# specified path is an
# absolute path or not
isabs = os.path.isabs(path)
print(isabs)


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

# Check whether the
# specified path is an
# absolute path or not
isabs = os.path.isabs(path)
print(isabs)

Output:

True
False
False

Code #2: Use of os.path.isabs() method (On Windows)

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

# importing os.path module
import os.path

# Path
path = r"C:\\Users\\Documents"

# Check whether the
# specified path is an
# absolute path or not
isabs = os.path.isabs(path)
print(isabs)


# Path
path = r"\\User\\Documents"

# Check whether the
# specified path is an
# absolute path or not
isabs = os.path.isabs(path)
print(isabs)


# Path
path = r"User\\Documents"

# Check whether the
# specified path is an
# absolute path or not
isabs = os.path.isabs(path)
print(isabs)

Output:

True
True
False
