Write a python script to find the factorial of a number.

# Function to find the factorial of a number
def factorial(n):
    if n < 0:
        return "Factorial is not defined for negative numbers"
    if n == 0 or n == 1:
        return 1
    result = 1
    for i in range(2, n + 1):
        result *= i
    return result

Here is the example usage:

print(factorial(5))
print(factorial(0))

This will output:

120
1

Write a python script to check if a number is prime.

# Function to check if a number is prime
def is_prime(n):
    if n <= 1:
        return False
    # Using Trial Division method to check for primality
    for i in range(2, int(n**0.5) + 1):
      if n % i == 0:
        return False
    return True

Here is the example usage:

print(is_prime(5))
print(is_prime(10))

This will output:

True
False
