排名不正确

Question

我根据得分、上场时间、罚球和效率对 NBA 排名前十的篮球运动员进行排名。但是，当我打印排名时，排名不正确。似乎是根据数字中每个字符的值对它们进行排名，但我希望它们按照前面提到的值的最高数量到最低数量进行排名。

我的代码：

def readData(filename):

    inputFile = open(filename, 'r')

    inputFile.readline()

    master_data_list = []

    for line in inputFile:
        master_data_list.append(line.split(","))

    return master_data_list

def points(master_data_list):

    pointList = []

    for player in master_data_list[:-3]:
        index = (player[1], player[2], player[6])
        pointList.append(index)

    return pointList

def minutes(master_data_list):

    minutesList = []

    for player in master_data_list[:-3]:
        index = (player[1], player[2], player[5])
        minutesList.append(index)

    return minutesList

def freethrows(master_data_list):

    freethrowsList = []

    for player in master_data_list[:-3]:
        index = (player[1], player[2], player[18])
        freethrowsList.append(index)

    return freethrowsList

def efficiency(master_data_list):

    effList = []

    for player in master_data_list:
        formula = int(((player[6] + player[9] + player[10] + player[11] + player[12])-((player[15] - player[16]) + (player[17] - player[18]) + player[13]))/(player[4]))
        index = (player[1], player[2], formula)
        effList.append(formula)

    return effList

def main():

    master_data_list = readData("player_career.csv")

    pointList = points(master_data_list)
    minutesList = minutes(master_data_list)
    freethrowsList = freethrows(master_data_list)
    #effList = efficiency(master_data_list)

    #got this code from 
    pointList = sorted(pointList, key = lambda x: x[2], reverse = True)
    minutesList = sorted(minutesList, key = lambda x: x[2], reverse = True)
    freethrowsList = sorted(freethrowsList, key = lambda x: x[2], reverse = True)
    #effList = sorted(effList, key = lambda x: x[2], reverse = True)

    print("Top 10 players based on total points scored.")
    for line in pointList[:10]:
        print(line[0], line[1]+"-"+line[2])
    print()

    print("Top 10 players based on total minutes.")
    for line in minutesList[:10]:
        print(line[0], line[1]+"-"+line[2])
    print()

    print("Top 10 players based on total free throws.")
    for line in freethrowsList[:10]:
        print(line[0], line[1]+"-"+line[2])
    print()

    """
    print("Top 10 players based on total efficiency.")
    for line in effList[:10]:
        print(line[0], line[1]+"-"+line[2])
    print()
    """

我还没有做效率，所以不包括在内。

这是输入文件的示例：

如果有人有想法让他们正确排名，谢谢。

Answer 1

请将此key = lambda x: x[2] 更改为key = lambda x: int(x[2]) 以比较整数，而不是字符串。

Answer 2

您需要将输入中的字符串更改为整数，例如：

def points(master_data_list):

    pointList = []

    for player in master_data_list[:-3]:
        index = (player[1], player[2], int(player[6]))
        pointList.append(index)

    return pointList
