Can't we add 1 and True to set ?

[Prakash]

result=set()
result.add(1)
result.add(True)
result.add('Science')
print(result)

Result returned:
{1, 'P'}

I am adding the values 1 & True to the set and set does not consider True. I am assuming that this is happening because True=1 and set does not allow duplicates.

Is this behavior right?

In my case 1 is an int and True is a bool.

Well, bool is a subclass of int. But the key point for sets is this: if hash(x) == hash(y) and x == y, then x and y are considered to be the same object for a set. This is the case for 1 and True (and also the case for 0 and False). It's also the case for 1 and 1.0.
