Question

Votes Needed to Win [5 points] 3.1 Many voting systems use the Droop Quota to determine if a candidate has enough votes to win: total votes RoundDown 1 winners 1 So far in this assignment we have been dealing with voting systems where there is only one winner in each riding. (This will change in section 4.) Note: When winners is 1, this means that each candidate needs a 50% + 1 majority to win. Complete and test the function votes needed to win Input: a list of ballots, an integer number of winners Return: the integer number of votes a candidate would need to win using the Droop Quota Examples: >> votes_needed_to_win([{ *CPC':3, 'NDP' :5}, {'NDP' :2, 'CPC':4}, 'CPC3, 'NDP' :5}], 1) 2 > votes_needed_to_win(['g']*20, 2) 7

Need some help with this question! Each dictionary is essentially one votes so first example total votes is 3. Please add comments to explain. Language is python

Answer 1

import math
def votes_needed_to_win(ballot,n):#start of function with two parameters ballot and number of winners
#math.floor rounds down the result
#len(ballot) gives the number of votes
#here 'n' is the number of winners
print(math.floor(len(ballot)/(n+1))+1)
