【问题描述】：

如果我打开一个包含人名及其分数的文本文件，如果有 2 个人都得分最高，我如何打印这两个名字。现在它只打印其中一个名称，我希望它打印两个，其他一切正常。提前致谢！！

这是我现在的代码：

maxName = ''
maxScore = 0
for line in file:
    i = line.strip().split()
    x = [int(y) for y in i[1:]]
    #print(z[0]," made ","$",sum(x))
    if sum(x) >= maxScore:
        maxName  = z[0]
        maxScore = sum(x)
print(f'The max total score is {maxScore}')       
print(f'those who scored the highest: {maxName}')

【解决方案1】：

它只打印一个，因为您只跟踪一个。要打印多个，请将它们全部记录在一个列表中。

maxNames = []  # Keep names in this list
maxScore = 0
for line in file:
    i = line.strip().split()
    x = [int(y) for y in i[1:]]
    
    #### Only calculate the sum once
    totalScore = sum(x)

    if totalScore > maxScore: # If greater, create a new list containing only this name
        maxNames  = [i[0]]
        maxScore = totalScore
    elif totalScore == maxScore: # If equal, append this name to the list
        maxNames.append(i[0])


print(f'The max total score is {maxScore}')       
print(f'those who scored the highest: {maxNames}')

要打印列表中的项目不附带括号和分隔符，您可以str.join() the elements in the list

printNames = ",".join(maxNames)
print(f'those who scored the highest: {printNames}')

【解决方案2】：

你可以先找到最高分，然后是所有有这个分数的人：

lines = [i.strip('\n').split() for i in file]
max_score = max([sum(b) for _, *b in lines])
has_max = [a for a, *b in lines if sum(b) == max_score]

将它们存储在一个列表中。我替你把i改成了z。

maxName = []
maxScore = 0
for line in file:
    z = line.strip().split()
    x = [int(y) for y in z[1:]]
    #print(z[0]," made ","$",sum(x))
    if sum(x) > maxScore:
        maxName  = [z[0]]
        maxScore = sum(x)
    elif sum(x) == maxScore:
        maxName.append( z[0] )
print(f'The max total score is {maxScore}')       
print(f'those who scored the highest: {maxName}')
