Here's my section of code:
with open(class_code+".csv", 'a') as csvfile:
fieldnames = ["Name", "Score 1", "Score 2", "Score 3", "Average"]
writer = csv.DictWriter(csvfile, fieldnames=fieldnames)
#writer.writeheader()
writer.writerow({"Name": name, "Score 1": score1, "Score 2": score2,
"Score 3": score3})
It prints when requested as:
Adam,1,0,0,0.3333333333333333
Jake,9,10,6,8.333333333333334
Tom,5,3,3,3.6666666666666665
So basically, if anyone called Adam, Jake or Tom tries the quiz again, it will
not let them.
Thanks
