How To Quicken This Algorithm In Python

The problem statement is: The player with the highest score is ranked 1 number on the leaderboard. Players who have equal scores receive the same ranking number, and the next play

Solution 1:

There's no need to append Alice's scores to scores. First make sure that scores is sorted from high to low.

Then for each score of Alice, calculate her rank as follows:

Start with rank = 1 and iterate over the list of scores. Add 1 to rank every time the score you're looking at is smaller than the previous one and return the value of rank as soon as the score you're looking at equals or is smaller than Alice's score.

EDIT

This answer assumes that only the highest score of each player is relevant.
