How do I get the filename without the extension from a path in Python?

How do I get the filename without the extension from a path in Python?

"/path/to/some/file.txt"  →  "file"

Python 3.4+

Use pathlib.Path.stem

>>> from pathlib import Path
>>> Path("/path/to/file.txt").stem
'file'
>>> Path("/path/to/file.tar.gz").stem
'file.tar'

Python < 3.4

Use os.path.splitext in combination with os.path.basename:

>>> os.path.splitext(os.path.basename("/path/to/file.txt"))[0]
'file'
>>> os.path.splitext(os.path.basename("/path/to/file.tar.gz"))[0]
'file.tar'
