Question

I'm having problems on PS1. I have written several iterations of this and sometimes it prints, sometimes it doesn't.

Answer 1

findprime = int(raw_input ('For which prime are you looking?'))
if findprime == 1: #block deals with 1, 2, and 3, which have different properties than remaining primes
print (2)
elif findprime == 2:
print (3)
else:
count = int(3)
num_candidate = int(5) #testing starts at 5
while count <= findprime:
for devisor in range (3, int(num_candidate ** 0.5), 2):
if num_candidate%devisor == 0:
num_candidate += 2 #if evenly divisible, move onto next odd candidate
print (num_candidate)
else:
count += 1
num_candidate += 2
print (num_candidate)
break
if count == findprime:
print (num_candidate)

Answer 2

You're printing num_candidate from 3 different places. It will help you if you add some text to the print statements so that you know which one is printing:
print( "from else num_candidate ==", num_candidate )

Logically, I would expect a break statement when "num_candidate%devisor == 0" to reset the for loop.
