List methods

The methods worth knowing

Method	What it does
.append(x)	add x to the end
.extend(other)	add every item from another list
.insert(i, x)	add x at position i
.remove(x)	delete the first x (error if absent)
.pop()	remove and return the last item
.pop(i)	remove and return item i
.sort()	sort in place
.reverse()	reverse in place
.count(x)	how many times x appears
.index(x)	position of the first x

The important distinction: .sort() changes the list and returns None, while sorted(list) leaves the original alone and hands back a new sorted list. The same pairing exists for .reverse() and reversed().

Also useful: sum(), min(), max() and len() all take a list directly.

Your turn: write process(scores) that removes the lowest score and returns the remaining scores sorted from high to low. Do not change the caller's list.

def process(scores):
    # Drop the lowest, return the rest sorted high to low.
    pass
