python how to find a set in a string code example

Example 1: python set &

>>> A = {0, 2, 4, 6, 8};
>>> B = {1, 2, 3, 4, 5};

>>> print("Union :", A | B)  
Union : {0, 1, 2, 3, 4, 5, 6, 8}

>>> print("Intersection :", A & B)
Intersection : {2, 4}

>>> print("Difference :", A - B)
Difference : {0, 8, 6}

# elements not present both sets
>>> print("Symmetric difference :", A ^ B)   
Symmetric difference : {0, 1, 3, 5, 6, 8}

Example 2: sets in python

The simplest way to create set is:
1. from list
code:
	s = [1,2,3]
	set = set(s)
	print(set)

2. s,add() method
code:
	set.add(1)
	set.add(2)
	set.remove(2)
	print(set)  // 1
