Write a python function proddigits() that inputs a positive integer number and returns the product of digits of that number. For example, if the input is 422, the function should return 16 (which is equal to 4×2×2 ).

Certainly! Here is a Python function `proddigits()` that takes a positive integer as input and returns the product of its digits:

def proddigits(num):
    # Initialize the product to 1
    product = 1
    
    # Convert the integer to a string
    num_str = str(num)
    
    # Iterate over each character in the string
    for char in num_str:
        # Convert the character back to an integer
        digit = int(char)
        
        # Multiply the digit to the product
        product *= digit
    
    # Return the final product
    return product

You can call this function with a positive integer argument to get the product of its digits. For example:

# Test the function
num = 422
print(proddigits(num))  # Output: 16

I hope this helps! Let me know if you have any other questions.
