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

For instance, if I had "/path/to/some/file.txt", I would want "

Answer 1

If you want to keep the path to the file and just remove the extension

>>> file = '/root/dir/sub.exten/file.data.1.2.dat'
>>> print ('.').join(file.split('.')[:-1])
/root/dir/sub.exten/file.data.1.2
