python - Sort nested dictionary by values

Question

I am trying to sort a dictionary with another dictionary inside. This is how my dict looks like:

{'POS2': {'stegano': 0, 'sum': 200, 'misc': 100, 'web': 0, 'ppc': 0, 'crypto': 0, 'admin': 0, 'vuln': 0, 'forensics': 0, 'hardware': 0, 'reverse': 0, 'recon': 100}, ...}

I want to sort it by 'sum' key that is stored in nested dict. I have tried different solutions like here Sort nested dictionary by value, and remainder by another value, in Python and here sorting a nested dictionary with lists in python but they all work fine on python 2.x but doesn't work on python 3.x. Could you give me advice how to implement this kind of sort ?

Answer 1

Simply return the desired sort key from each item

sorted(inputdict.items(), key=lambda item: item[1]['sum'])
