At least with the latter, you can do:

stringtype = (str, unicode) isinstance(x, stringtype) Hmmmm... Or can you?

Yes -- it's the value of the expression that counts, not how it's spelled. You can even nest these tuples:

inttypes = int, long filetypes = file, def fori(x): ... return isinstance(x, (int_types, file_types)) ... fori(43) 1 fori(43L) 1 import sys fori(sys.stdin) 1 fori(43.0) 0
