Python Set Methods
Set methods for collection operations — union, intersection, difference, and more. This category documents 17 Python set methods entries, and each page gives you the full syntax, the parameter list, the return value, and a runnable example. The entries include: set.add(), set.remove(), set.discard(), set.pop(), set.clear(), set.union(), set.intersection(), set.difference(), set.symmetric_difference(), set.issubset(), set.issuperset(), set.isdisjoint(), set.copy(), set.difference_update(), set.intersection_update(), set.symmetric_difference_update(), set.update(). set.add() adds an element to the set if not already present. set.remove() removes element x; raises KeyError if not found. set.discard() removes element x if present (does nothing if not found). set.pop() removes and returns an arbitrary element. Raises KeyError if empty. set.clear() removes all elements from the set. For a structured walkthrough of the whole topic, read the Set Methods guide. Set Methods belongs to the Built-in Types group alongside String Methods, List Methods, Dictionary Methods, Tuple Methods.
