## Issue

I am doing some Python exercisses and for some reason my fucntion is returning to me opposite bool value. If statement under the function need to has "not" to work properly – can anyone explain me what am I doing wrong?

```
number = int(input("Enter numbers you want to check: "))
def dividers(number):
temp_tab = range(2, number)
divider = 0
for x in temp_tab:
while number % x == 0:
divider += 1
if divider > 1:
return False
else:
return True
if not dividers(number):
print("It is a prime number")
else:
print("It is not a prime number")
```

## Solution

It seems like you want a function to check if a number is prime:

```
def is_prime(number):
if number <= 1: return False
for x in range(2, number):
if number % x == 0:
return False
return True
number = int(input("Enter numbers you want to check: "))
if is_prime(number):
print("It is a prime number")
else:
print("It is not a prime number")
```
