Question

HELP!! I'm stuck on ps1a. here's my code: http://dpaste.com/532527/

my reasoning behind the program is this:

give prime the value 1.
give even_number the value 2.
set up a loop to repeat the process 999 times.
add prime and even number to be new value for prime.
check to see if prime can be evenly divided by numbers from 2 up to but not including prime.
if it can be divided evenly by any number from 2 to but not including prime.
keep adding 2 to even number and repeating until prime is not evenly divisible by 2 to but not including prime.
after the loop is completed to obtain the prime make

Answer 1

oops my reasoning got cut, here it is is full: give prime the value 1.
give even_number the value 2.
set up a loop to repeat the process 999 times.
add prime and even number to be new value for prime.
check to see if prime can be evenly divided by numbers from 2 up to but not including prime.
if it can be divided evenly by any number from 2 to but not including prime.
keep adding 2 to even number and repeating until prime is not evenly divisible by 2 to but not including prime.
after the loop is completed to obtain the prime make even_number equal 2 again.
print prime.

Answer 2

my problem is that it won't let me divide by a tuple. any suggestions to get around this problem?

Answer 3

You cannot divide by a tuple. You can divide by numbers in a tuple if you like, but tuples are containers, not numbers.

Answer 4

You might want to try creating a list of primes since nonprimes cannot be divided evenly by primes.

Answer 5

polpak: what i was trying to do was, as you said, divide by the numbers contained in the tuple. I just can't figure out how to do it

Answer 6

for number in mytuple:
if prime % number == 0:
# prime is not prime.

Answer 7

ooooooooooh tats how you do it
thanks
