Answer:
a= input("Enter the last name of first candidate: ")
aVotes= int(input("Enter Number of votes cast for "+ a + ": "))
b= input("Enter the last name of second candidate: ")
bVotes= int(input("Enter Number of votes cast for "+ b + ": "))
c= input("Enter the last name of third candidate: ")
cVotes= int(input("Enter Number of votes cast for "+ c + ": "))
d= input("Enter the last name of fourth candidate: ")
dVotes = int(input("Enter Number of votes cast for "+ d + ": "))
e= input("Enter the last name of fifth candidate: ")
eVotes = int(input("Enter Number of votes cast for "+ e + ": "))

Explanation:
- First section
<em> a= input("Enter the last name of first candidate: ") </em>
<em>aVotes= int(input("Enter Number of votes cast for "+ a + ": ")) </em>
<em>b= input("Enter the last name of second candidate: ") </em>
<em>bVotes= int(input("Enter Number of votes cast for "+ b + ": ")) </em>
<em>c= input("Enter the last name of third candidate: ") </em>
<em>cVotes= int(input("Enter Number of votes cast for "+ c + ": ")) </em>
<em>d= input("Enter the last name of fourth candidate: ") </em>
<em>dVotes = int(input("Enter Number of votes cast for "+ d + ": ")) </em>
<em>e= input("Enter the last name of fifth candidate: ") </em>
<em>eVotes = int(input("Enter Number of votes cast for "+ e + ": ")) </em>
Collects the last name and the number of votes cast
- Second section
<em>votes= [aVotes,bVotes,cVotes,dVotes,eVotes] </em>
<em />
places all the votes in a list.
The reason for this is to allow us use the "sum function" and "max function", to get the sum of all the votes.
- Third section
<em>aPercent= (round((aVotes/sum(votes))*100, 2)) </em>
<em>bPercent= (round((bVotes/sum(votes))*100, 2)) </em>
<em>cPercent= (round((cVotes/sum(votes))*100, 2)) </em>
<em>dPercent= (round((dVotes/sum(votes))*100, 2)) </em>
<em>ePercent= (round((eVotes/sum(votes))*100, 2)) </em>
calculates the percentage of all the votes cast for the individual candidates
- Fourth section
<em>print( a, ":", aVotes,"Votes", aPercent,"%") </em>
<em>print( b, ":", bVotes,"Votes", bPercent,"%") </em>
<em>print( c, ":", cVotes,"Votes", cPercent,"%") </em>
<em>print( d, ":", dVotes,"Votes", dPercent,"%") </em>
<em>print( e, ":", eVotes,"Votes", ePercent,"%") </em>
prints out the candidates name, number of votes received and the percentage
- Fifth section
winner= max(votes)
gets the maximum votes cast
- Sixth Section
if winner==aVotes:
print(a," is the Winner")
elif winner==bVotes:
print(b," is the Winner")
elif winner==cVotes:
print(c," is the Winner")
elif winner==dVotes:
print(d," is the Winner")
elif winner==eVotes:
print(e," is the Winner")
else:
None
uses if statements to compare the maximum votes with the votes gotten by all the candidates to get a winner
