Your function does not computer real primes, all it does is asks if a number is divisible by two.

It compute if a number is a prime you need every number from 2 to that number if any of them can divide evenly you break it.

**EXAMPLE:**

```
def is_prime(get_number, display=True):
prime = True
_numbers_to_number = [number for number in range(2, get_number)]
for number in _numbers_to_number:
if get_number % number == 0:
prime = False
break
if prime:
if display:
print("%s is a prime" % prime)
return get_number
elif not prime:
if display:
print("%s is not a Prime" % get_number)
```
