如何根据值显示索引？

Question

这是我的代码示例：

budi = {"Name" : "Budi", "Gender" : "Male", "Age" : 18}
ahmad = {"Name" : "Ahmad", "Gender" : "Male", "Age" : 7}
ika = {"Name" : "Ika", "Gender" : "Female", "Age" : 18}

marged = [budi, ahmad, ika]

我想要这样的结果，例如基于18岁：

The oldest participants are: Budi and Ika

根据您在问题中提出的问题，这是代码。请完成这个非常简单的实现。

from operator import itemgetter

budi = {"Name" : "Budi", "Gender" : "Male", "Age" : 1}
ahmad = {"Name" : "Ahmad", "Gender" : "Male", "Age" : 7}
ika = {"Name" : "Ika", "Gender" : "Female", "Age" : 18}

marged = [budi, ahmad, ika]

newlist = sorted(marged, key=itemgetter('Age'), reverse=True)

maxAge = newlist[0]["Age"]
finalList = [newlist[0]["Name"]]
for person in newlist[1:]:
    if person["Age"] == maxAge:
        finalList.append(person["Name"])

if len(finalList) == 1:
    print "The oldest participant is: " + finalList[0]
else:
    print "The oldest participants are: ",
    for name in finalList:
        print name+" ",
