Simple example of how to write to a CSV File using Python

writetocsv.py

import csv


f = open('scores.csv','a') # 'a' stands for APPEND / ADD TO
# use  'w' if you want to replace the whole file's contents...

writer = csv.writer(f)

fname = input("First name: ")
lname = input("Last name: ")
score = input("Score: ")

row = [fname,lname,score] #Put all the inputs together in a list to make a row.
writer.writerow(row) #Add the row to the scores.csv file
f.close() #Save the file - YOU  MUST DO THIS TO SAVE THE CHANGES TO THE FILE!!!!!
