The Python set union() method returns a new set with distinct elements from all the sets. Python set() Method The set() is a constructor method that returns an object of the set class from the specified iterable and its elements. remove () Removes the specified element. Let us go through the different methods present as built-in Python for Sets. The principle outlined above generally applies: where a set is expected, methods will typically accept any iterable as an argument, but operators require actual sets as operands. If the element is already present, it doesn't add any element. Creating Sets in Python. This is a shallow copy. You can define a set simply just by naming all of its elements inside brackets. set() method is used to convert any of the iterable to sequence of iterable elements with distinct elements, commonly called Set.
