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

I have a basic piece of coding which follows:

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"])

I have sorted out it so it will print out people's names in alphabetical order, however, I now need the code working so it would print out the names in alphabetical order, but also so it prints out the highest score only.

Your scores are stored in three separate keys; use the max() function to pick the highest one:

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

You could make your life easier by storing all the scores in a list, rather than three separate keys:

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

You can then still address individual scores with pupil['scores'][index] (where index is an integer, pick from 0, 1 or 2), but the highest score is then as simple as max(pupil['scores']).
