Can you manipulate bits and memory directly using Python? If yes, wouldn't that be a best option to dealing with performance-critical spots than C bindings?

Based on what I've read about python, I think this is the one thing that python can't do, almost by design. – joshin4colours Mar 10 '12 at 3:39

Manipulating bits and memory is low level, but that doesn't mean it will improve performance much. – Pubby Mar 10 '12 at 4:26

You can write your own extension in C and there manipulate bits and memory.

Are you sure you are cpu-bound and need this?
