Answer:
Written in Python
parties = []
votes = []
total = 0
for i in range(0,3):
  party = input("Party: ")
  vote = int(input("Vote: "))
  parties.append(party)
  votes.append(vote)
  total = total + vote
for i in range(0,3):
  print(parties[i]+"\t\t\t"+str(votes[i])+"\t\t\t"+str(round((votes[i])*100/total,2))+"%")
Explanation:
This declares an empty list for parties
parties = []
This declares an empty list for votes
votes = []
This initializes total votes to 0
total = 0
The following iteration allows user to enter details for party and corresponding votes
for i in range(0,3):
  party = input("Party: ")
  vote = int(input("Vote: "))
  parties.append(party)
  votes.append(vote)
This calculates the total vote
  total = total + vote
The following iteration prints the required details
for i in range(0,3):
  print(parties[i]+"\t\t\t"+str(votes[i])+"\t\t\t"+str(round((votes[i])*100/total,2))+"%")
