As it is written, don't you always win if you hit enter?
It may be the approved cheat code, though...

OP:

("some string")

is not a tuple, it is the same as just

"some string"

therefore

option1 = "some string"
if input() in option1:
    print("yes")

prints 'yes' if the user types in a substring of option1, and the shortest 
substring of any string is "".

For a single-item tuple the trailing comma is mandatory:

>>> ("some string") # string
'some string'
>>> "some string", # tuple
('some string',)
>>> ("some string",) # tuple, parens added for clarity
('some string',)

In general a tuple is consituted by the comma(s), not the parentheses:

>>> "one", "two"
('one', 'two')
