No, if by 'byte array' mean (mutable) bytearray.
Yes, in the sense that a byte string is an (immutable) array of ints in
range(256).
Is a byte array the same as an array.array?
No, if by 'byte array' you mean the same as bytes.
Yes, if you mean bytearray and array.array('B'), in the sense that
bytearray is based on array.array('B').
If I remove this line from my code, where 'data' has

data=array.array('B',data)
then it still works - Python 3.
In 3.3, data = bytearray(data) would have the same effect, and the only
effect is to make data mutable, but if you do not mutate the image
bytes, that is useless.
