You already got answers for the "is" vs. "==" difference. I'd like
to add the following.
In which cases should we use the is() function ?
"is" is not a function, It's an operator, just like == or +.
is() function makes comparaison of (abstract representation of)
adresses of objects in memory.
That's an implementation detail. CPython (and maybe others)
implement "is" in terms of memory addresses. Other implementations
might use an object ID number or whatever else.
