SET Method : isdisjoint()

Working: It will return True if all the elements of A set are absent in Other B set. Otherwise it return false. Disjoint means there are no relation of A set with B set in any way.

Syntax:

set1.isdisjoint(set2)

Example:

A = {3, 1, 0, 6}

B = {2, 7, -4}

print(A.isdisjoint(B))

Result:

True

SET Method : issubset()

Working: It returns True if ALL items / elements of A set, present in B set, otherwise it return False

Syntax:

setA.issubset(setB)

Example:

A = {3, 1, 0, 6}

B = {2, 7, -4, 3,0,10,8,6,1}

print(A.issubset(B))

print(B.issubset(A))

Result:

True

False

SET Method : issuperset()

Working: When A set is the subset of B set, then B set will be superset of A set. It is opposite to sub set concept.

Syntax:

setB.issuperset(setA)

Example:

A = {5, 2, 4, 6}

B = {7, 1, 5, 2, 6, 9, 4, 12}

True

True

B = {11,13,14,15}

A.update(B)

print(A)

Result:

{7, 1, 5, 2, 6, 9, 4, 11, 13, 14, 15}
