What originally was meant to be a quick script to determine how much total XP is needed to reach a certain level turned into an exercise showing the value of knowing the summation formula rather than simply going for the brute-force method
import timeit
import math
def total_xp(level):
"""
Uses a loop to compute the total amount of xp
needed to reach a certain level.
"""
total = 0
