You could just .split it:
>>> Path('logs/date.log.txt').stem.split('.')[0]
'date'
os.path works just as well:
>>> os.path.basename('logs/date.log.txt').split('.')[0]
'date'
It passes all of the tests:
In [11]: all(Path(k).stem.split('.')[0] == v for k, v in {
....: 'a': 'a',
....: 'a.txt': 'a',
....: 'archive.tar.gz': 'archive',
....: 'directory/file': 'file',
....: 'd.x.y.z/f.a.b.c': 'f',
....: 'logs/date.log.txt': 'date'
....: }.items())
Out[11]: True

Why not go recursively?
from pathlib import Path
def true_stem(path):
stem = Path(path).stem
return stem if stem == path else true_stem(stem)
assert(true_stem('d.x.y.z/f.a.b.c') == 'f')

Python's pathlib Module: Taming the File System – Real Python
5 days ago - When using .write_text(), Python overwrites any existing files on the same path without giving you any notice. That means you could erase all your hard work with a single keystroke! As always, when you write files with Python, you should be cautious of what your code is doing. The same is true when you’re renaming files. ... When you want to rename files, you can use .with_stem(), .with_suffix(), or .with_name().
