I am more familiar with C++ than python. So I need to connect python
concept to C++ concept so that I can understand it better.

name1 and name are all references (in the C++ sense), right?

__repr__  and __str__ are references (in the C++ sense) to functions
and both of them could refer to the same function or two different
ones, right?
