Rightmost Place on the Map

A map is a list of (label, x) pairs. The class Place is empty.

Write two functions:

make_places(pairs) makes one Place for each pair, gives it a label attribute and an x attribute, and returns the list of places in the same order.
rightmost_label(places) takes a list of Place objects and returns the label of the one with the biggest x.
- If two places tie, return the one that comes first.
- An empty list gives back "".

rightmost_label must read the attributes off the objects. The tests only ever hand it what make_places built.

Examples

make_places([('gate', 7), ('pond', 2)])[1].label

returns 'pond'

places = make_places([('gate', 7), ('pond', 2)])

returns 'gate'

places = make_places([("cafe", 4), ("park", 9), ("shop", 2)])

returns 'park'

make_places([("cafe", 4)])[0].x

returns 4
