I am writing a python code that needs an efficient data structure to hold MANY bits.

I think the container, bitset in C++, perfectly fits my need. Note I know there is a class bitarray in python that can provide the same functions.

However, I really need my code to be VERY fast, so I am going to use cython to make use of the efficiency of C++.

And since that, how can use bitset ???

Thanks a lot!

Not easily. The issue is that `bitset` is templated with a number indicating its length and Cython does not handle non-class templates (i.e. numbers) well. – DavidW Jan 23 '17 at 10:14
@DavidW yes, It's the very evil. – user3903457 Jan 25 '17 at 03:20
