Question

Is there any built-in sorted data structure in python?

Answer 1

Yes. List is sortable. Dict is also sortable. Just use:
>> d = [3, 5, 67, 325, 546]
>> d.sort()
>> d
[3, 5, 67, 325, 546]

You can also sort by default, no... but there are lists and you know you have to sort them after creating them.
