python question for practice

1. Write the a program check leap year or not using python.

def is_leap_year(year):

    if year % 4 == 0 and (year % 100 != 0 or year % 400 == 0):

        return True

    return False

year = 2024

if is_leap_year(year):

    print(f"{year} is a leap year.")

else:

    print(f"{year} is not a leap year.")

Output:  2024 is a leap year

2. Write the a program find factorial using python .

def factorial(n):

    if n == 0:

        return 1

    else:

        return n * factorial(n - 1)

num = 5

print(f"The factorial of {num} is {factorial(num)}.")

Output:  The factorial of 5 is 120 .

3.   write the a program find the prime number using python.

def is_prime(num):

    if num <= 1:

        return False

    for i in range(2, int(num**0.5) + 1):

        if num % i == 0:

            return False

    return True

num = 17

if is_prime(num):

    print(f"{num} is a prime number.")

else:

    print(f"{num} is not a prime number.")

Output:   17 is prime number.
