Search file with *filename* python 3.8

[lastyle]

But os.Path.Isdir returns the complete path

No it return True or False,it dos a test if it's a folder and that folder exits.

>>> os.path.isdir(r'E:\div_code\pan')
True
>>> os.path.isdir(r'E:\div_code\pan999')
False

So I need to check if the return value if it contains bestfile.

This i don't understand,in code dos regex .*bestfile.* the check,and only return files that match this regex.

Sure, finding Files works like a charm. But as this is a work in Progress i didnt notice earlier that there may exist Folders like bestfileV2.0 which contain e.g. Updatev2.0.exe which belongs to bestfile but doesnt match the Filename. So i need to cover that aswell sadly
