Top five names with score

Question

I have a programming challenge at school where i make a game and at the end, it prints the top five scores of all time. I have been able to get it to print the top five scores but I dont know how to make it print the score with the username along it. The code is:

with open("login.csv") as f:
    print(" ")
    print(" ")
    print("Usernames and scores:")
    reader=csv.reader(f)
    scores=(row[-1] for row in reader)
    topscore=sorted(scores, reverse=True)
    top5=topscore[:5]
    print(top5)

The output i get is:

Usernames and scores:
['82', '80', '66', '64', '62']

My desired output however is:

Usernames and scores:
Dylan, 82
f, 80
Farai, 66
Dylan, 64
Dylan, 62

Any help Dylan

I missed this out but the columns go name, password, score. Sorry for missing that out guys.

Answer 1

You can sort the rows together with a key function that allows the sorting to be based on the last column:

with open("login.csv") as f:
    print(" ")
    print(" ")
    print("Usernames and scores:")
    reader=csv.reader(f)
    topscore=sorted(reader, key=lambda row: int(row[-1]), reverse=True)
    top5=topscore[:5]
    print('\n'.join(', '.join((username, score)) for username, _, score in top5))

Answer 2

It appears you're selecting only the score through the list comprehension. Assuming that the CSV is something like < username > , < score >, maybe the following will work?

with open("login.csv") as f:
    print(" ")
    print(" ")
    print("Usernames and scores:")
    reader=csv.reader(f)
    scores=(row for row in reader)
    topscore=sorted(scores, reverse=True)
    for score in topscores:
        print(score[0] +",\t" + score[1])
