Okay, in case you’re a computer geek (and/or want to critique my noob code)…here’s the two main Python files that make up the raffle:raffle.py
#! /usr/bin/python3
import csv
import random
import sys
# import sleep to show output for some time period
from time import sleep
import list_animation
import my_clear
# Import raffle file, etc.
raffleFile = open('raffle.csv')
attendees = csv.DictReader(raffleFile)
attendeeNames = []
ticketNumbers = []
# Clear screen; everything will stay top left
my_clear.clear()
# Create two ordered lists
# (ticketNumbers and attendee names)
# from .csv file
for row in attendees:
ticketNumbers.append(row['Ticket Number'])
attendeeNames.append(row['Name'])
# Spin the virtual raffle machine unless
# the user types 'q' or 'Q'
print()
print()
print('Ready to Raffle, #HowNotToSailer?')
while True:
print()
print()
print('Press \'y\' (and Enter) to spin the drum,')
answer = input('or \'q\' (and Enter) to quit. ')
print()
# answer = input()
if answer == ('q' or 'Q'):
break
# Get the number of raffle tickets
# Note: the index starts at 0 , not 1...!
listSize = len(ticketNumbers)
# Get a random number between 0 and
# the maximum number.
# NOTE: The index numbers go from ZERO
# to one less than the number of entries.
spin = random.randint(0, (listSize - 1))
list_animation.raffle_animation()
my_clear.clear() #Clear screen before next raffle
# Display the 4-digit raffle ticket number
print()
print()
print('You picked Ticket Number: ' + f'{spin:04}')
print()
print(' /----------------------\\')
print(' | |')
print(' | ' + f'{spin:04}' + ' |')

# Find and display the winner's name
winner = str(attendeeNames[spin])
print()
print('The winner is... ' + '\033[32;1m' + winner.upper() + '\033[0m' + '!')
# So far, this displays all the ffplay status,
# which runs the winner off the screen
