How do you add 5 to every mark without a loop?

Short answer. Use a numpy array: m + 5.

What does tolist() do?

It turns the array into a list.

Remember

Install: python -m pip install numpy
Arrays work on all at once

Grace marks for everyone, no loop? Here m is a numpy array of marks. Plus five adds to every mark at once. Tolist makes a list. Mean gives the average. Install numpy with pip. Arrays work on all at once.
