I am trying to sort the python dictionary based on the values in ascending order. However, if the value is the same then the items should be sorted on the basis of the keys in descending order.

input={-1: 1, 5: 1, -6: 2, 4: 2, 1: 3}
desired_output={5:1, -1:1, 4:2, -6:2, 1:3}

Can anyone suggest an efficient way to do this?

This is the method I have used so far.

dic=dict(sorted(dic.items(),key=lambda x:x[1]))

You can sort by tuple, so just change the key argument to this:

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