Path or PurePath

[Skaperen]

i am writing a function that may be given a pathlib Path or PurePath object, or a string, or bytes, or bytearray. the first two are what concerns me. how can i test what it is that the function is getting when called? will a test for Path be True if what i got was really a PurePath? or the reverse? or are they distinctive enough for isinstance() to tell them apart? i don't know,yet, if i do need to tell them apart. this function will be a file tree recursion generator yield Path objects of all types found in the tree. i have already done such a function that yields strings. i want to make this more useable.
