The Project Euler thread

[Reincarnate]

I am going to be going through the problems, posting a cumulative timing of all problems from 1 through whatever problem I am on, using Python (including time taken to import any external stuff I write/use for each problem, individually):

So far:

Total time for problems 1 through 10: 0.734290 seconds

edit:

Total time for problems 1 through 25: 3.879866 seconds

Total time for problems 1 through 40: 7.787901 seconds
