Write A Program To Read Election Data And Generate Reports
Write a Program to Read Election Data and Generate Reports
For this assignment, you will write a program that reads election data from a file and processes that data in several different ways, including writing a report to a different file. The data file format is structured with each county's name followed by the number of registered voters and the number of ballots counted, with each item on a separate line. County names are listed in alphabetical order. Your program should allow the user to specify the input filename, process the data, and generate a report file named with the prefix 'REPORT' followed by the input filename. Additionally, it should display summary statistics in the Python shell window, including total counties, total registered voters, total ballots counted, overall percentage of voters who cast ballots, number of counties with less than 50% voter turnout, and percentage of counties with more than 80% turnout.

The objective of this program is to efficiently process election data stored in a structured text file and provide comprehensive reports both in a new file and in the console for quick analysis. This involves reading data, performing calculations, and outputting results in a clear, organized manner.
Initially, the program prompts the user to enter the filename of the election data. It then opens and reads the file line by line, processing each county's data in a single loop. To achieve this, the program maintains counters for the total number of counties, total registered voters, and total ballots cast. It also uses variables to track the number of counties with less than 50% turnout and those with more than 80%. During each iteration, the program updates these counters and calculates the percentage of registered voters who cast ballots for the current county.
The data processing involves reading a county name, then the number of registered voters, and the number of ballots cast, converting string inputs to integers for calculations. For each county, the program computes the voter turnout percentage and writes a line to the report file showing the county name and percentage of voter participation, rounded to one decimal place, followed by a '%' sign.
After processing all counties, the program writes a summary of cumulative statistics into the console. These include the total number of counties listed, total registered voters, total ballots counted, the overall percentage of registered voters who cast ballots in the state, the number of counties with less than 50% turnout, and the percentage of counties with more than 80% turnout. Calculations for overall percentages involve dividing the total ballots by total registered voters, as well as computing the proportion of counties falling into predefined turnout categories.
The implementation employs efficient programming practices, including proper variable initialization, descriptive variable names, and inline comments for clarity. It also ensures the files are properly closed after processing, handles potential issues such as line ending characters, and advises thorough testing with sample data files to validate correctness in different scenarios.
