Use os.path.splitext:
Copy>>> import os
>>> filename, file_extension = os.path.splitext('/path/to/somefile.ext')
>>> filename
'/path/to/somefile'
>>> file_extension
'.ext'
Unlike most manual string-splitting attempts, os.path.splitext will correctly treat /a/b.c/d as having no extension instead of having extension .c/d, and it will treat .bashrc as having no extension instead of having extension .bashrc:
Copy>>> os.path.splitext('/a/b.c/d')
('/a/b.c/d', '')
>>> os.path.splitext('.bashrc')
('.bashrc', '')

New in version 3.4.
Copyimport pathlib
print(pathlib.Path('/foo/bar.txt').suffix)
# Outputs: .txt
print(pathlib.Path('/foo/bar.txt').stem)
# Outputs: bar
print(pathlib.Path("hello/foo.bar.tar.gz").suffixes)
# Outputs: ['.bar', '.tar', '.gz']
print(''.join(pathlib.Path("hello/foo.bar.tar.gz").suffixes))
# Outputs: .bar.tar.gz
print(pathlib.Path("hello/foo.bar.tar.gz").stem)
# Outputs: foo.bar.tar
I'm surprised no one has mentioned pathlib yet, pathlib IS awesome!

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'

Is there any situation where string.endswith() would not be suitable for checking for a specific file extension?
They don't behave the same: >>> from os.path import splitext >>> splitext('pic.jpg')[1] == '.jpg', 'pic.jpg'.endswith('.jpg') (True, True) >>> splitext('....jpg')[1] == '.jpg', '....jpg'.endswith('.jpg') (False, True) There's also a bit of weirdness with regard to names like archive.tar.gz. You might even consider checking like this to play it safe: >>> from pathlib import Path >>> Path('archive.tar.gz').suffixes == ['.tar', '.gz'] True >>> Path('pic.png').suffixes == ['.png'] True More on reddit.com

Get filename with extension removed: here's how in Python
Python has several ways to get a folder’s content. One option is the Path.iterdir() method. This method returns all items of a directory, but won’t go into subdirectories. So we only get the files and folders in the directory itself. To get the filename without the last extension from those directory items, here’s what we do: from pathlib import Path # Specify the directory to get the filenames without extension from dir_path = Path(r"C:\Wallpapers") # Loop over all directory entries.

Python 3.4+
Use pathlib.Path.stem
Copy>>> 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:
Copy>>> 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'

Note that if your file has multiple extensions .stem will only remove the last extension. For example, Path('file.tar.gz').stem will return 'file.tar'.
