It would probably be more correct to say that "value types" and
"assignment" work differently in Python compared with Java/C++. More
specifically, in Java/C++, "value types" like int or Integer are
mutable, and the "=" operator mutates them. In python, they are
immutable, and the "=" operator never mutates objects, but instead inds
a variable / attribute / etc. to a new object reference.
