sorted Dictionary to list

Okay so I'm trying to sort a dictionary of key values pairs in a dictionary. The keys are words and values are decimal values. I'm trying to get a list of sorted keys based on the values. right now I have: 

sortedList = sorted(wordSimDic, key=wordSimDic.get,reverse=True)

This works. However, I would like to be able to do one thing further. If the values of the keys match I would like them to be sorted in the outputlist by the key in alphabetical order. 

For example

    Input:
    {'c':1,'a':1,'d':3}

    Output:
    [a,c,d]

 right now my output is:
    [c,a,d]

Do you have suggestion.Thanks so much!

In general, to 'sort by X then Y' in Python, you want a key function that produces an (X, Y) tuple (or other sequence, but tuples are simplest and cleanest really). Thus:

sorted(wordSimDic, key=lambda k: (wordSimDic.get(k), k), reverse=True)
