Victor Stinner a écrit :
I suppose that each codec will have a different list of accepted input and
output types. Example:
bz2: encode:bytes->bytes, decode:bytes->bytes
rot13: encode:str->str, decode:str->str
hex: encode:bytes->str, decode: str->bytes
A user point of view: please NO.
This might be more consistent with the semantics, but it forces users to scratch
their head each time to find out which types are involved. I'd rather all
methods take and return the same types, independant of codec, that is:
.encode : str->bytes
.decode : bytes->str
.(un)transform : same type, str->str or bytes->bytes
All other uses can be trivially done with .encode('ascii')/.decode('ascii').
Changing the type of *ascii* text is easy, understanding bytes vs str semantics
is not!
Cheers,
B.
