如何按字母顺序和最高数字对列表中的字典进行排序

How to order a dictionary within a list by alphabetical order and highest number

我有一段基本的编码如下:

dict1 = [{"Name":"Ron","one":3,"two":6,"three":10}
         ,{"Name":"Mac","one":5,"two":8,"three":0}
         ,{"Name":"DUDE","one":16,"two":9,"three":2}]

print(dict1)
import operator

dict1.sort(key=operator.itemgetter("Name"))

print("\nStudents Alphabetised\n")
for pupil in dict1:
    print ("StudentName",pupil["Name"],pupil["one"],pupil["two"],pupil["three"])

我已经整理好了,它会按字母顺序打印出人们的名字,但是,我现在需要代码工作,这样它会按字母顺序打印出名字,而且它只打印出最高分.

您的分数存储在三个单独的键中;使用 max() function 选择最高的:

for pupil in dict1:
    highest = max(pupil["one"], pupil["two"], pupil["three"])
    print("StudentName", pupil["Name"], highest)

通过将所有分数存储在一个列表中,而不是三个单独的键,您可以让您的生活更轻松:

dict1 = [
    {"Name": "Ron", 'scores': [3, 6, 10]},
    {"Name": "Mac", 'scores': [5, 8, 0]},
    {"Name": "DUDE", 'scores': [16, 9, 2]},
]

然后您仍然可以使用 pupil['scores'][index] 来解决单个分数(其中 index 是一个整数,从 0、1 或 2 中选择),但是最高分数就像 [=15] =].
