What is issubset method in Python?

A subset is a type of set that is a part of another set. For example, the earth is a set that contains many elements, and it is also a subset of the solar system.

issubset() is the set method used to check if a set is a subset of another set or if a whole set is part of another set.

Illustration

A = {1,2,4}
B = {1,2,3,4,5}
c = A.issubset(B)
if c == True:
print('set A is a subset of B')
else:
print('set A is not a subset of B')

Here, in this example, we take 2 sets called A and B.

  • b contains all the elements of a so set a is called the subset of b.

  • we then print the same thing using a print statement.
