Python program to determine if a given number is prime or not
To determine if a given number is prime or not in Python, you can check if it's divisible by any number other than 1 and itself. Here's a Python program to do that:
def is_prime(number):
# Prime numbers are greater than 1
if number <= 1:
return False
# Check for factors from 2 to the square root of the number
for i in range(2, int(number**0.5) + 1):
if number % i == 0:
return False
return True
# Example usage:
input_number = int(input("Enter a number: "))
if is_prime(input_number):
print("The number is prime.")
else:
print("The number is not prime.")
```
This program prompts the user to input a number, and then it checks if the number is prime or not using the `is_prime` function. The `is_prime` function returns `True` if the number is prime, and `False` otherwise.
