Python Set issubset()

Python’s set.issubset(set) returns True if all elements of this set are members of the specified set argument. It determines whether the set on which the method is called is the subset of the specified set. Here’s a minimal example that checks whether sets s is a subset of t: Another minimal Harry Potter example: Syntax … Read more

Python Set issuperset()

Python’s set.issuperset(set) returns True if all elements of the specified set argument are members of this set. It determines whether the set on which the method is called is the superset of the specified set. Here’s a minimal example that checks whether set s is a superset of t: Another minimal Harry Potter example: Syntax … Read more

Python Set pop()

Python’s set.pop() method removes and returns an arbitrary element from the set. If no element is present — that is, you call it on an empty set — set.pop() raises a KeyError. Here’s a minimal example where you remove a string element that happens to be ‘Alice’ from the set by means of the s.pop() … Read more

Python Set add()

Python’s set.add(element) method adds the element to this set. If the element is already present in the set, the method returns without any side effect. Here’s a minimal example where we add element 4 to an existing set: Syntax Let’s dive into the formal syntax of the set.add() method. set.add(element) Argument Data Type Explanation element … Read more

Python Set union()

Python’s set.union(set_1, set_2, …) creates and returns a new set consisting of the elements that are members of any of the involved sets. The resulting set has at least as many elements as any other set given in the argument list. Here’s a minimal example that creates a new set arising from the union of … Read more

Python Set update()

Python’s set.update(set_1, set_2, …) performs the union of all involved sets and updates the set on which it is called. It adds all members of the set argument(s) to the set on which it is called. For example, s.update({1, 2}) adds elements 1 and 2 to the original set s. Here’s a minimal example that … Read more

Python Set Methods

All set methods are called on a given set. For example, if you created a set s = {1, 2, 3}, you’d call s.clear() to remove all elements of the set. We use the term “this set” to refer to the set on which the method is executed. add() Add an element to this set … Read more
