# Unpacking Sequences

# * can be used to denote that all items in a sequences that are not assigned
# already should be assigned

# Create a sequence of candidates

# Unpack the sequence, seperating the four values of candidatesRankedByVote into
# four variables.
winner, runnerUp, thirdPlace, fourthPlace = candidatesRankedByVote

# View those four variables.

# Unpack the sequence, create two variables, one with the winner, and one with
# all the non-winners.

electedCandidate, *nonElectedCandidate = candidatesRankedByVote

print('Victor:', electedCandidate, ', Losers:', nonElectedCandidate)

# Create three variables, one for the candidate with the most votes, one for
# the candidate with the least votes, and one for the middle candidates.
# Specifically, the * takes everything between the first and last variable assignment.
