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.
