Don't ever try and map C++ to Python on a 1:1 basis or you will get
quite confused. Try this thought experiment, and remember, the Python
shell is your best friend now!
IDLE 2.6.2
>>> a = 1
>>> b = 1
>>> a
1
>>> b
1
>>> id(a)
27822424
>>> id(b)
27822424
>>> help(id)
Help on built-in function id in module __builtin__:
id(...)
id(object) -> integer
Return the identity of an object. This is guaranteed to be unique
among
simultaneously existing objects. (Hint: it's the object's memory
address.)
NOW you can apply that logic 1:1 to your python problem ;-)
