os.walk(Path("path_string")) giving error

[Larz60+]

p looks like a pathlib Path, not an os path.
Hard to be sure without full code.

dir = "E:\\Books"
p = Path(dir)

if that is the case, then you can still use os, but you must resolve p first:

os.walk(p.resolve())

better to use a pathlib walk instead (Google: 'pathlib equivalent of os.walk')
