Python's pathlib Module: Taming the File System – Real Python

In Python 3.4+, you can use the pathlib module (included in Python's standard library):
>>> from pathlib import Path
>>> p = Path("/home/user/Downloads/repo/test.txt")
>>> print(p.stem)
test
>>> print(p.name)
test.txt

Use the os.path module to work with paths; the os.path.basename() function gives you the last part after the last path separator, and os.path.splitext() gives you the filename with the extension split off:
import os.path
basename = os.path.splitext(os.path.basename(f.name))[0]
Using the os.path functions ensures that your code will continue to work correctly on different operating systems, even if the path separators are different.
In Python 3.4 or newer (or as a separate backport install), you can also use the pathlib library, which offers a more object-oriented approach to path handling. pathlib.Path() objects have a .stem attribute, which is the final component without the extension suffix:
try:
import pathlib
except ImportError:
# older Python version, import the backport instead
import pathlib2 as pathlib
basename = pathlib.Path(f.name).stem
Demo:
>>> import os.path
>>> a = "/home/user/Downloads/repo/test.txt"
>>> os.path.basename(a)
'test.txt'
>>> os.path.splitext(os.path.basename(a))
('test', '.txt')
>>> os.path.splitext(os.path.basename(a))[0]
'test'
>>> import pathlib
>>> pathlib.Path(a)
PosixPath('/home/user/Downloads/repo/test.txt')
>>> pathlib.Path(a).stem
'test'

May 22, 2024 - As we have seen, Path objects only represent files but don't perform operations on them. However, they do have certain methods for common file operations. We will see how to use them in this section. Reading file contents is a fundamental operation in many Python applications. pathlib provides convenient shorthand methods for reading files as either text or raw bytes.
