Unfortunately pure-python don't adopt the simpler and faster numpy way of doing Assignment, and calling len() inside the loop as in[False]*len(sieve[((k*k)/3)::2*k])is too slow. So i had to improvise to correct input (& avoid more math) and do some extreme (& painful) math-...
I initially thought the numpy preallocation approaches would be faster, since there is no dynamic variable expansion in the loop, but this does not seem to be the case. The approach that I find the most intuitive is the last one, where each image occupies a separate dimensions along the thi...
