Understanding Set data structure

Table of content

Set is an unordered data-structure with no duplicates. One can define set using {} curly brackets.

checking the type() and len() of set.

Trying to access data-elements using index throws an error.

checking dir on set object

1) set.add(x) : adds an element to set.

2) set.clear() : clears out the elements from the set.

3) set.copy() : returns deep copy of set object

4) set.difference(<set_object>) : returns the diff of two or more set objects.

5) set.difference_update(<set_obj>) : removes all the element from current object. (Minus operation)

6) set.discard(x) : remove pass element from set if it is member.

7) set.intersection(<set_obj>) : returns intersection of two set objects.

8) set.intersection_update(<set_obj>) : Update the current set object with intersection.

9) set.isdisjoint(<set_obj>) : Verify whether two set object has NULL intersection. If yes, then returns True else False

10) set.issubset(<set_obj>) : Verifies whether current set is subset object passed.

11) set.superset(<set_obj>) : Verifies whether current set object is superset of passed object. If yes, then returns True else False.

12) set.pop() : removes and returns arbitrary element from set. Gives KeyError if passed value is not present in set.

13) set.remove(x) : remove passed value from set. If that value is not present in set gives KeyError.

14) set.symmetric_difference(<set_obj>) : returns symmetric_differenece of two set.

15) set.symmetric_difference_update(<set_obj>) : update the current set with symmetric differenece.

16) set.union(<set_obj>) : returns the union of two sets.

17) set.update(<set_obj>) : update the set with union between itself and passed set object.
