Description
Define a subclass of tuple such that it supports the __contains__ special method
(corresponding to the in operator in reverse) that works similar to the str version.
For your information,
But tuple does not support slice containment:
Define a subclass of tuple named STuple such that containment works for both
elements and slices:
''' you should use the template of following.'''
import ast
class STuple(tuple):
'''inherit constructor'''
def __contains__(self, item):
#coding on here
#coding on here
#coding on here
if __name__ == '__main__':
pat = ast.literal_eval(input()) # pattern input
testSeq = ast.literal_eval(input()) # test case input
for p in pat:
for t in testSeq:
print(f'{p} in STuple{t} =', p in STuple(t))
