Sort dict alphabetically

Question

My program can output every student's name and their 3 scores from a dict in a file, but I need to sort the data by alphabetical order. How can I sort the names and scores alphabetically according to the surname?

This is my code so far: import pickle

def clssa():
    filename="friendlist.data"
    f=open('Class6A.txt','rb')
    storedlist = pickle.load(f)
    for key, value in storedlist.items():
        sorted (key), value in storedlist.items()  
        print (("{} --> {}").format(key, value))

Solution 1

Use the sorted keyword.

for key, value in sorted(storedlist.items()):
    # etc

Solution 2

Dictionaries are not ordered, so you have to sort the keys and then access the dictionary:

for key in sorted(storedlist.iterkeys()):
    print (("{} --> {}").format(key, storedlist[key]))

You can keep it simpler with 'for key, value in sorted(storedlist.interitems())'

As of python 3.6+, dictionaries are ordered.
