Python tips-True or false

The following code was found in yesterday's blog about substring:

You may have discovered that in Python 3, there is actually a way to complete the function with only one row:

>>> Def issubstring2 (S1, S2 ):
Return true if s2.find (S1 )! =-1 else false
But... Can it be simpler?
How can we use python to express conditional statements more easily? Just for fun
One way is to use the List Index:
>>> Def issubstring2 (S1, S2 ):
Return [false, true] [s2.find (S1 )! =-1]
The principle is very simple. If the Boolean value true is evaluated as 1 by the index, and false is equal to 0, can it be simpler? Leave a message to me
