Sort by values (descending) and then keys (ascending) in Python dictionary

Question

I have the following dictionaries:

mydict1 = {1: 11, 2: 4, 5: 1, 6: 1}
mydict2 = {1: 1, 5: 1}

For each one of them I'd like to first sort by values (descending) and then keys (ascendingly), yielding this output:

out_dict1 = [((1, 11), (2, 4), (5, 1), (6, 1)]
out_dict2 = [(1, 1), (5, 1)]

What's the way to do it?

I used this but cannot get the result consistently for two cases above:

sorted(mydict.items(), key=lambda x: (x[1],x[0]))

Answer 1

Since you want to sort the values in descending order, just negate the value of values in the function passed to the key parameter, like this

sorted(mydict.items(), key=lambda x: (-x[1], x[0]))

Now, the values will be sorted in the descending order and if two values are equal, the keys will be considered and they will be sorted in the ascending order.
