My calculation of primenumbers is nearly working out, only sometimes it gives a primenumber that is not a primenumber at all, like 5405, 5615, 6035 or even 95. I find it really weird and do not see why this happens...
My Code is here:

Best ResponseYou've already chosen the best response.0the % operator might help http://docs.python.org/2.7/library/stdtypes.html#numerictypesintfloatlongcomplex strategically placed print statements can help alot  it shows you what is going on in your code

Best ResponseYou've already chosen the best response.1Are you just trying to find the n\(^{th}\) prime? Because it also skips 2 and 3....

Best ResponseYou've already chosen the best response.1And you forgot to reset your divisor when you find something is nonprime, so the test point is past 5 when it checks 95.

Best ResponseYou've already chosen the best response.1Oh... one last thing, you are doing an import math... why?

Best ResponseYou've already chosen the best response.1I made a fixed version. I suggest playing with mod, %, like bwCA says and resetting divisor to 3 on failures. If that does not do it, then look at the fixed version. http://dpaste.com/hold/1325399/

Best ResponseYou've already chosen the best response.1This one is also based on yours, does not use %, and deals with another issue... the +2 after finding the last prime! http://dpaste.com/hold/1325422/
