Superset and Subsets

In Python, you can use the concepts of superset and subset to compare relationships between sets.

Subsets

Theory

A set $A$ is considered a subset of another set $B$ if every element of $A$ is also an element of $B$ .

(A \subseteq B)

set_A = {1, 2, 3}
set_B = {1, 2, 3, 4, 5}

# Check if set_A is a subset of set_B
is_subset = set_A.issubset(set_B)
print(is_subset)

True

Theory

A set $B$ is considered a superset of another set $A$ if every element of $A$ is also an element of $B$ .

(A \supseteq B)

set_A = {1, 2, 3}
set_B = {1, 2, 3, 4, 5}

# Check if set_B is a superset of set_A
is_superset = set_B.issuperset(set_A)
print(is_superset)

True
