Tidy a function (2/2)

Tidy a function

Someone left this function in a state. Make it match the target shown in the panel below the prose, exactly — same lines, same order, same indentation of four spaces per level.

What’s wrong with the buffer, top to bottom:

a leftover print line has to go
count is computed before the loop instead of after it
the body of the loop was split across two lines and lost its indent
LEN should be lowercase
the result should round to two places, not one

If a step has you stuck, lesson 4 covers selecting and deleting, lesson 6 moving lines through registers, and lesson 8 joining, indenting, changing case, and adjusting numbers. Undo is always there if a change goes wrong.

Make the file match the target

def average(scores):
    total = 0
    for score in scores:
        total = total + score
    count = len(scores)
    return round(total / count, 2)

Last one — goal check runs when it's done
