Depends on how you write your code. If you use the bytearray type
(which John didn't, despite his apparent believe that he did),
then no conversion additional conversion is needed.
According to PEP 3137, there should be no distinction between
the two for read purposes. In 2.6, there is. That's a bug.
If we something like the following for the bytes type in 2.7, perhaps
we could improve the 2.X behavior (and make everyone happier).
class bytes(str):
def __getitem__(self, index):
# keep exceptions the same
result = super(bytes, self).__getitem__(index)
if isinstance(index, int):
# Picking out a single char
return ord(result)
# otherwise, it an extraction, return a similar type.
return bytes(result)
def __repr__(self):
# make a nice visible-in-debugger type
return 'b' + super(bytes, self).__repr__()
At the very least, you can smuggle this into your programs
to check out their behavior.
