Reorder dictionary in python according to a list of values

Question

Let us consider a dictionary:

sample_dict={1:\'r099\',2:\'g444\',3:\'t555\',4:\'f444\',5:\'h666\'}

I want to re-order this dictionary in an

Answer 1

If you're using an OrderedDict, you can do

for key in [5,2,4,3,1]:
    my_ordered_dict[key] = my_ordered_dict.pop(key)

This reinserts everything in your ordered dict in the sequence you want, such that later you can do

my_ordered_dict.values()

And get the list you suggested in the question.

If you wrap the reinsertion in a try: ...; except KeyError: pass, you can reorder an OrderedDict even if not all the keys in your list are present.
