🔹 Other Set Methods

add() - Adds an element to the set

clear() - Removes all elements from the set

copy() - Returns a shallow copy of the set

discard() - Removes a specified element if it exists (no error if not found)

pop() - Removes and returns a random element from the set

remove() - Removes a specified element (raises error if not found)


🔹 Set Operations

difference() - Returns the difference between sets (elements in one but not the other)

difference_update() - Removes elements found in another set from this set

intersection() - Returns common elements of two or more sets

intersection_update() - Updates the set with elements found in both sets

isdisjoint() - Returns True if sets have no elements in common

issubset() - Returns True if all elements of a set are in another set

issuperset() - Returns True if a set contains all elements of another set

symmetric_difference() - Returns elements not common to both sets

symmetric_difference_update() - Updates the set with elements not common to both sets

union() - Returns a new set containing all unique elements from sets

update() - Updates the set with union of itself and others



Q1. Create a set named fruits containing "apple", "banana", and "mango".

Q2. Create two sets: A = {1, 2, 3, 4, 5} and B = {4, 5, 6, 7}. Find the intersection of A and B.

Q3. Create two sets: X = {"red", "blue", "green"} and Y = {"yellow", "blue", "black"}. Find the union of X and Y.

Q4. Create two sets: P = {10, 20, 30, 40} and Q = {30, 40, 50, 60}. Find the difference (P - Q).

Q5. Create two sets: M = {"dog", "cat", "parrot"} and N = {"cat", "rabbit", "lion"}. Find the difference (N - M).

Q6. Write Python code to create a set of numbers from 1 to 5 and another set from 4 to 8, then find both intersection and union.

Q7. Given two sets A = {2, 4, 6, 8} and B = {1, 2, 3, 4}, find:
a) A ∩ B
b) A ∪ B
c) A - B
d) B - A
