Python os.path.splitext() method is an efficient way to split a path name into a pair of root and ext. The ext means extension, which has the extension part of the specified path, while the root part is everything except the ext part.

Syntax of Python os.path.splitext() Method

os.path.splitext(path)

Parameters

path an address object of a file system path or a symlink. The object can either be an str or bytes

Return

The return type of this method is a tuple representing the ext and root parts of the specified path name.

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

import os

path = "home/user/File.txt"

split = os.path.splitext(path)

print("The root part of '% s' is:" % path, split[0])

print("The ext part of '% s' is:" % path, split[1])

Output:

The root part of 'home/user/File.txt' is: home/user/File
The ext part of 'home/user/File.txt' is: .txt

As seen in the above code, the first element of the tuple is the root, and the subsequent one is the ext component.

Example 2: If There Is No ext Part in os.path.splitext() Method

import os

path = "home/user/Desktop"

split = os.path.splitext(path)

print("The root part of '% s' is:" % path, split[0])

print("The ext part of '% s' is:" % path, split[1])

Output:

The root part of 'home/user/Desktop' is: home/user/Desktop
The ext part of 'home/user/Desktop' is:

The os.path.splitext() splits the text at the right-most period. The ext part is empty if there is no period in the file address.

Example 3: Shorter Syntax of the os.path.splitext() Method

import os

print(os.path.splitext('temp.bar.exe'))

Output:

('temp.bar', '.exe')

The above example shows that the file path’s leading periods are considered part of the root.

Example 4: Concatenate the root and ext Part in the os.path.splitext() Method

import os

path = "/home/user/Desktop/File.txt"

root, ext = os.path.splitext(path)

print("The root part is: ",root)

print("The ext part is: ",ext)

path_address = root + ext

print("The full path address is: ", path_address)

Output:

The root part is:  /home/user/Desktop/File
The ext part is:  .txt
The full path address is:  /home/user/Desktop/File.txt

In any case, concatenating the root and ext components will always make the original path.

Example 5: Create a Different File Extension Using the os.path.splitext() Method

import os

path = "/home/user/Desktop/File.txt"

root, ext = os.path.splitext(path)

print("The root part is: ",root)

print("The ext part is: ",ext)

path_address = root + '.exe'

print("The full path address is: ", path_address)

Output:

The root part is:  /home/user/Desktop/File
The ext part is:  .txt
The full path address is:  /home/user/Desktop/File.exe

Using the above code, you can easily have a new file address with a new name.
