A New Name on the Board

A player asks to change the name shown on the scoreboard. Their points must stay the same.

Write rename_player(scores, old_name, new_name) that moves the points from old_name to new_name, removes old_name, and returns the dictionary.

old_name is always on the board.
new_name is never already on the board, unless it is the same as old_name. In that case nothing should change, and the player must still be there with their points.

Examples

scores = {'ada': 3, 'grace': 5}

old_name = 'ada'

new_name = 'ada_l'

returns {'grace': 5, 'ada_l': 3}

scores = {"ada": 3, "grace": 5, "linus": 2}

old_name = "linus"

new_name = "torvalds"

returns {'ada': 3, 'grace': 5, 'torvalds': 2}

scores = {"bo": 7}

old_name = "bo"

new_name = "bob"

returns {'bob': 7}
