Thanks. I would have guessed that I'd want low-level style code;
that's the sort of thing I have in mind. In fact the only thing
that seems likely to come up right now is looping through an
array of bytes, modifying them. The plan is to use the array
module first to convert a string or a list to an array, outside
the accelerated part, then maybe do something like
for j in range(len(bytes)/3):
g = (bytes[3*j] + bytes[3*j+1] + bytes[3*j+2])/3
bytes[3*j] = bytes[3*j+1] = bytes[3*j+2] = g
If len(bytes) is large, you might want to use `xrange`, too. `range`
creates a list which is not really what you need.
