Comparing sets
Python allows to check if a set is a subset of another set. Set A is a subset of B if B contains all the elements of A and has some other elements as well. This can be done through a standard comparison operator:
a = {1, 3, 5, 7, 18}
b = {1, 7, 18}
if b <= a:
print('B is a subset of A')
elif a <= b:
print('A is a subset of B')
else:
print('Not a subset!')This will print
B is a subset of A. A contains all the elements of B (1, 7, 18) and has some additional ones as well (3, 5). To find the whole list of possible operations with Python sets visit their official page but these are the main operations that we will be focusing on.
