Search file with *filename* python 3.8

[snippsat]

lets assume there is a directory that matches my searchpattern, how do i reflect that ?

In the last code with os.walk() it only search for files(in all sub-folders).
So if a folder it's named folderbestfile it will not be in result,
but files with bestfile names in this folder will be in result as wanted.

If need in a other cases to check if something is a file or folder can use.

os.path.isfile(path)
os.path.isdir(path)

Or if using pathlib.

my_file.is_file()
my_file.is_dir()
