find 'yesterdays files'

[tester_V]

Well, I tried Gribouillis snipped and it works.
I have a question.
I have already a variable 'path'
I tried to use it

f=path

but the code fails.
I'm wondering what does it mean?

f=Path

from pathlib import Path
import datetime as dt

yesterday = dt.datetime.now().date() - dt.timedelta(days=1)
dirtoscan = "c:\\0001\\"
for fl in os.listdir(dirtoscan) :
    path = os.path.join(dirtoscan,fl)
    #f = path
    f = Path(path)
    if yesterday == dt.datetime.fromtimestamp(f.stat().st_mtime).date():
        print(f"File was last modified yesterday - {f}")

I did not try another snippet, it looks complicated, I do not understand it.

Thank you!
