Feel free to show the docs that contradict this, but this is not correct. In fact, I think you are talking about Javascript rather than Python.

We have just explained it, and this is not the reason. If a value is
equal to (==) 3, then it is exactly equal to 3. But, as previously
discussed (particularly with numbers above 255), a value of 3 does not
need to be the same object (is) as another 3. They can be two identical
numbers, stored in the same way, but as separate objects in memory, thus
return False when tested with 'is'. This is clearly demonstrated with:
>>> a = 2020
>>> a is 2020 # False
So, it has absolutely nothing to do with multiplication.

That's 2 operators, and one doesn't exist in Python, again, you may be
thinking of Javascript. The operators are '==' and 'is'.
