Im on lecture 2 and cannot figure out how to separate odd numbers and prime numbers! I figured out how to generate odd numbers here http://dpaste.com/535600/ How do I get primes out of that?

Is there a specific interval of numbers that you want?
you want to put another loop in between line 6 and line 7 and it should be indented to the same level as line 6. that inner loop needs to test the number to see if it is prime
the new loop will be 'nested' 'inside' the 'outer' loop (the while loop)
Not the answer you are looking for? Search for more explanations.
How do I test it to see if it is a prime? Do I have to divide it by a number, etc lol im lost
A prime number evenly divides by itself and 1 ONLY. So n/n=1 & n/1=n. Both of these have remainder of 0. If n divided by any integer between 1 and n has a remainder of 0, then n is NOT prime. Use the modulus (%) operation to find if a number has a remainder. Ex. n=15. 15%2=1 (15/2= 7 with remainder of 1). 15%3=0 (15/3= 5 with remainder of 0). So since there is at least 1 divisor (besides 1 & 15), in this case, 3, that returns 0, then 15 is not a prime.
That link doesn't seem to work, should do? Erm, just go to the list of questions and it is currently the one at the very top. The title is
grupiyati: help with p1 anyone
There's a solution here if you wanted one.
This might help.
if number < 2:
for each in range(2, (number+2) / 2):
if number % each == 0:
tally, n = 0, 0
while tally < 1000:
n += 1
tally += 1
