It can be used to rebuild a database if the database is destroyed without a viable backup. It can also help a developer track down elusive errors when an application has gone to production. You will need basic Python programming and SQL skills for this lab: - [Certified Associate in Python Programming Certification](

    Add Logging to

    You should add logging to Create a separate log file for each item. The file should be named <item-number>.log. The log level should be info and each log message should be date:level:message. Finally, log the final tally message.

    import logging
    def tally_votes(data):
        the example voting data and operations are in the __main__ section
        write code that will ask for user input for item number being voted on
        create a log file named <voting item>.log
        tally votes and log each vote
        using: tally = f"Item: {voting_item} Yes: {yes} No: {no}"
        return tally
        voting_item = input("What is the item number for this vote? ").strip()
        file_name = f"{voting_item}.log"
            format='%(asctime)s:%(levelname)s:%(message)s', level=logging.INFO)
        yes = 0
        no = 0
        for vote in data:
            if vote == 'y':
                yes += 1
                no += 1
            # log vote
        tally = f"Item: {voting_item} Yes: {yes} No: {no}"
        return tally
    if __name__ == "__main__":
        voting_data = ["y", "n", "y", "y", "y", "n"]
        tally = tally_votes(voting_data)
