Sets in Python

 SETS

The sets are nothing but the collections of well defined objects, In set of the python it defined by the "set" function into the variable.

s = set()
print(type(s))

<class 'set'>

    Note: In python to make a list is always used by "[....]" square brackets 

a = [1, 2, 3, 4]
This_is_a_set = set(a)
print(This_is_a_set)

{1, 2, 3, 4}

There is a function ".add" which adds the elements into the sets during programing.

code👇

s1 = set()
s1.add(23)
s1.add(23)
print(s1)

{23}

".add" function can add the elements but it never acept the same number/ string element.

s1 = set()
s1.add(23)
s1.add(20)
s2 = s1.union({1, 2, 3})
print(s1, s2)

{1, 2} {1, 2}

".union" function makes the new set

".intersection" function intersects the two variables
