Please can anyone help me out with this code?? What's the problem.

Question

def is_prime(number):

for i in range(2,number):
if number%i==0:
return False
return True
print(is_prime(15))
print(is_prime(3))

def prime_numbers(n):
for i in range(1,n):
if is_prime(number):
return i
print("\n",prime_numbers(40))

Answer 1

I guess you were trying to pass i and did number instead.....since number is nowhere defined in the function or program it will show not defined error.

def prime_numbers(n):
for i in range(1,n):
if is_prime(i): # ---replaced code---
print(i)

Answer 2

If you are checking a range of values (from 1 to <n> in the code), then you should be checking this instead, inside the for-loop,

if is_prime( i ):

Also you might wanna `print( i )` rather than `return i` when <i> is a prime.

By changing `prime_numbers()` to print prime numbers in range, you then only need to call `prime_numbers()`, no need to print it, as `prime_numbers()` function doesn't return anything usable to be printed.

Remove your `is_prime()` tests for number 15 and 3 when you're done verifying `is_prime()` function.

And you can put Python in the thread tags, which clarifies language context better than a '6', up there ☝
