Union basically represents all the distinct elements of the corresponding sets altogether. Python Set union() method finds the union of the sets and represents a new set which contains all the items from the corresponding input sets. Note: If a…
Python Set Intersection basically finds and returns elements common among the sets. Syntax: set1.intersection(set2) is equivalent to set1 ∩ set2. Arguments: Accepts one or more sets as an argument. Return Value: Returns a set as output which contains elements common…
