I find pretty often that I want to loop through characters in a file:
while True:
c = f.read(1)
if not c: break
...
or sometimes of some other blocksize instead of 1. It would sure
be easier to say something like:
for c in f.iterbytes(): ...
or
for c in f.iterbytes(blocksize): ...
this isn't anything terribly advanced but just seems like a matter of
having the built-in types keep up with language features. The current
built-in iterator (for line in file: ...) is useful for text files but
can potentially read strings of unbounded size, so it's inadvisable for
arbitrary files.
Does anyone else like this idea?
