How to Get a Filename Without Its Extension in Python?

Retrieving Filename without Extension from a Path in Python

Determining the filename excluding its extension is a common task when working with paths. In Python, achieving this can be accomplished in several ways.

Python 3.4 and Above

Leveraging the pathlib module's stem attribute provides a straightforward approach for retrieving the filename without the extension:

from pathlib import Path

path = Path("/path/to/file.txt")
filename_without_extension = path.stem

print(filename_without_extension)  # Outputs: "file"

Python Versions Prior to 3.4

For Python versions before 3.4, a combination of the os.path.splitext and os.path.basename functions can be utilized:

import os.path

path = "/path/to/file.txt"

filename = os.path.basename(path)
filename_without_extension = os.path.splitext(filename)[0]

print(filename_without_extension)  # Outputs: "file"

This approach ensures compatibility with older Python versions while achieving the objective of extracting the filename without the extension.
