Function to Determine Prime Status in Python

In this exercise, you will develop a Python program with a function called "is_prime" that takes an integer as input and returns True if the number is prime, or False if it is not. This exercise is perfect for practicing function definition, conditional statements, and loops in Python. By implementing this function, you will gain hands-on experience in handling function definitions, conditional statements, and loops in Python. This exercise not only reinforces your understanding of functions but also helps you develop efficient coding practices for managing user interactions.

Objective

Develop a Python program with a function called "is_prime" that takes an integer as input and returns True if the number is prime, or False if it is not.

For example, if is_prime(127) returns True, then the number 127 is prime.

Example Python Exercise

 Copy Python Code 
# Define the function to check if a number is prime
def is_prime(number):
    # Check for numbers less than 2 (they are not prime)
    if number < 2:
        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:  # If a factor is found, number is not prime
            return False
    
    # If no factors are found, number is prime
    return True

# Main function to test the is_prime function
def main():
    # Test the function with a prime number
    print(is_prime(127))  # Expected output: True
    
    # Test the function with a non-prime number
    print(is_prime(100))  # Expected output: False

# Call the main function to execute the program
main()

 Output

True
False
