Project Analysis

A Colarado Elections Board employee was given a task to complete the audit of a recent election.

1. Calculate the total number of votes cast.
2. Get a complete list of candidates who received votes.
3. Calculate the total number of votes each candodate received.
4. Calculate the percentage of votes each candidate won.
5. Determine the winner of the election based on popular votes.

• The winner of the election was Diana DeGette who received 73.8% of the votes and 272,892 number of votes.

The script was written with flexibility in mind and it can be used for the election audit of any city as long as the csv file is written in the same order.

The section of the code that saves the result of the analysis doesn't assume what the number of the counties or the candidates are, that is information is found after the code iterates through each line in the data file provided.

1    # Save the final candidate vote count to the text file.
2    for candidate_name in candidate_votes:
3
4        # Retrieve vote count and percentage
5        votes = candidate_votes.get(candidate_name)
6        vote_percentage = float(votes) / float(total_votes) * 100
7        election_results = (
8            f"\n{candidate_name}: "
9            f"{vote_percentage:.1f}% "
10           f"({votes:,})\n"
11           )

Each candidate's name and votes are stored the candidate_vote Dict. The output variable election_results (Line 7) stores the output for each candidate found in the dictionary object.
