What have you actually tried? You haven't shown any actual code.

Look up the method dict.keys, and see how you might use that. Then
 look up random.shuffle, and see what it would do. Also look up
 dict.sort, since your two messages on this thread imply two
 conflicting goals as to which sub dictionaries should go in which
 of your buckets. 

As for extracting 20% of the keys, slicing is your answer. If
 there are 100 keys, 20, 30, and 50 need to be sliced
 off.

Then you'll need a loop to build each result dictionary from its keys.

There are shortcuts,  but it's best to learn the fundamentals first.

Try writing the code. If it doesn’t all work show us what you've
 tried, and what you think is wrong. And when you get an
 exception, show the whole traceback,  don't just paraphrase one
 of the lines.
