Get filename without extension in Python

This post will discuss how to get a filename without an extension from the specified path in Python.

1. Using `os.path.splitext()` function

The standard solution is to use the os.path.splitext(path) function to split a path into a (root, ext) pair such that root + ext == path. This returns the path to the file without extension. If the file has multiple periods, leading periods are ignored.

import os

dir = '/path/to/some/file.txt'

print(os.path.splitext(dir)[0]) # /path/to/some/

2. Using `str.rsplit()` function

Alternatively, you can use the str.rsplit() function to split on the last period.

dir = '/path/to/some/file.txt'

print(dir.rsplit('.', 1)[0]) # /path/to/some/

3. Using `pathlib.Path.stem()` function

If you don’t need the complete path, you can use the pathlib module in Python 3.4+. You can use its stem property that returns the file name without its extension:

from pathlib import Path

dir = '/path/to/some/file.txt'

print(Path(dir).stem) # /path/to/some/
