byte types

[Skaperen]

i find many times i write some code or a function or a method that does something with strings and i want it to also handle byte strings since i use those a lot. so initially i coded a test like:

if isinstance(variable,(bytes,bytearray)):
    ...

which woks OK in Python3 but fails in Python2 because bytes is the same as str in Python2. so, i came up with this way to do the test so that it only tests for bytearray when in Python2 when bytes is the same as str:

if isinstance(variable,(bytes,bytearray)[bytes==str:]):
     ...
