Question

我一直在尝试从csv文件中获得前5名的记分牌，但我一直在努力。

这是我的代码，如果有人可以帮助您，将不胜感激

while True:
if attempt == 2:
    print("You have no more guesses...You Loose!")
    print("Here is the scoreboard")

    user = str(input("Enter a name to save your highscore: "))
    file = open ("scoreboard.csv", "a")
    file.write("\n")
    file.write(user)
    file.write(",")
    file.write(str(points))
    file.write("pts")
    file.write("\n")

Answer 1

您可以尝试使用此功能。除非您希望它们之间有换行符，否则您无需在开头和结尾处换行。您还希望使用“打开时”自动关闭文件。

while True:
if attempt == 2:
    print("You have no more guesses...You Loose!")
    print("Here is the scoreboard")
    user = str(input("Enter a name to save your highscore: "))
    with open("scoreboard.csv", "a") as output:
        output.write("\n"+user+","+str(points)+" pts")

Answer 2

CSV模块非常方便。
user和points紧随您的输入。
使用的是Python 3.6 +。

import csv


with open('scoreboard.csv', 'a') as f:
    writer = csv.writer(f)
    writer.writerow([user, f"{points}pts"])

scoreboard.csv
例如：user =“ john”，点数= 10

john,10pts

Answer 3

csv为：

david,12
bill,8
joe,18
henry,15
nathan,10

您可以使用此功能：

import csv

def top_five():
    top = []
    all_scores = []

    with open('scores.csv', newline='') as csvfile:
        scores = csv.reader(csvfile)

        for row in scores:
            all_scores.append((row[0], int(row[1])))

        top = sorted(
            all_scores, 
            key=lambda score: score[1], 
            reverse=True)
    return top[:5]

print(top_five())

如果您将“ pts”保留在csv中，请在all_score列表中插入之前解析结果。如果您有列名，请跳过for循环的第一行。
