What does the % Operator do?

The % operator in Python is known as the modulus operator. It performs a calculation where it divides one number by another and gives you the remainder of that division.

To break it down:

- Usage: When you use dividend % divisor, it calculates how much is left after dividing dividend by divisor.

- Example: Let's look at your specific example from the lesson:

divisor = 4
dividend = 25

# compute remainder
remainder = dividend % divisor

print(remainder)    # Output: 1 

In this case, when you divide 25 by 4, the quotient is 6 (because 4 goes into 25 six times, making 24), and the remainder is 1 (because 25 - 24 = 1).

This can be really useful in programming when you need to check whether a number is even or odd or to limit an index to a certain range.

If you have any more questions about how to use the % operator or if you'd like further examples, feel free to ask! Hope this helps!
