Checking if a set is a subset of another set in python. The following code shows how to find a subset on set in python. This is the solution of the HackerRank Check Subset Python Sets problem.
Code:
T = int( input() )
for x in range(0,T):
n = int(input())
A = set(input().split())
m = int(input())
B = set(input().split())
if len(A.difference(B)):
print('False')
else:
print('True')
