## Question

Asked By – Dejas

I’m a little confused about the python `in`

operator for sets.

If I have a set `s`

and some instance `b`

, is it true that `b in s`

means “*is there some element x in s such that b == x is true*“?

**Now we will see solution for issue: Python’s “in” set operator **

## Answer

Yes, but it *also* means `hash(b) == hash(x)`

, so equality of the items isn’t enough to make them the same.
