Python Get Filename Without Extension From Path

  1. Get Filename Without Extension From Path Using pathlib.path().stem Method in Python
  2. Get Filename Without Extension From Path Using os.path.splitext() and string.split() Methods in Python
  3. Get Filename From Path Using os.path.basename() and os.path.splitext() Methods in Python

This tutorial will demonstrate various methods to get filename without extension from the file path in Python. Suppose the goal is to get the name of files from the list of file paths available in the form of a string, like from the path Desktop/folder/myfile.txt, we get only the filename myfile without .txt extension.

Get Filename Without Extension From Path Using pathlib.path().stem Method in Python

The path().stem method takes the file path as input and returns the file name by extracting it from the file path. For example, from the path Desktop/folder/myfile.txt, it will return myfile without the .txt extension.

The code example below demonstrates how to use the path().stem to get file name without the file extension from the file path:

from pathlib import Path

file_path = "Desktop/folder/myfile.txt"
file_name = Path(file_path).stem
print(file_name)

Output:

myfile

Get Filename Without Extension From Path Using os.path.splitext() and string.split() Methods in Python

The path.splitext() method of the os module takes the file path as string input and returns the file path and file extension as output.

As we want to get the file name from the file path, we can first remove the file extension from the file path using the os.path.splitext() method. The first element of the splitting result is the file path without extension. This result is further split it using / as the separator. The last element will be the filename without extension. The code example below demonstrates how to get filename without extension from the file path using path.splitext() and string.split() methods.

import os

file_path = "Desktop/folder/myfile.txt"

file_path = os.path.splitext(file_path)[0]
file_name = file_path.split('/')[-1]
print(file_name)

Output:

test

Get Filename From Path Using os.path.basename() and os.path.splitext() Methods in Python

In Python the path.basename() method of the os module takes the file path as input and returns the basename extracted from the file path. For example, the basename of Desktop/folder/myfile.txt is myfile.txt.

As we want to get filename from the file path, the basename can be extracted using the path.basename() method and filename using path.splitext(). The code example below demonstrates to get filename from the file path using path.basename() and path.splitext() methods.

import os

file_path = "Desktop/folder/myfile.txt"

basename = os.path.basename(file_path)
file_name = os.path.splitext(basename)[0]
print(file_name)

Output:

myfile
Warning

In case the file has a name like myfile.tar.gz, all the methods explained above will return myfile.tar as the filename.

Suppose we need to get filename without the part after . like myfile instead of myfile.tar from the path Desktop/folder/myfile.tar.gz, the string.index() method can be used to extract only myfile from myfile.tar. But the drawback of this method is if the . is part of the file name like my.file.tar.gz, it will return my as the file name.

The code example below how we can use string.index() to remove .tar from the output myfile.tarof methods explained above:

file_name = "myfile.tar"
index = file_name.index('.')
file_name = file_name[:index]
print(file_name)

file_name = "my.file.tar"
index = file_name.index('.')
file_name = file_name[:index]
print(file_name)

Output:

myfile
my
