No, python doesn't pass variable either by value or by reference. The
behavior in pytho

These statements are both wrong. Function argument objects or objects
derived therefrom are bound to function parameter names

One of the many lovely things about programming in the
Python style is that very few things need to be global.

Python does not use "call by value" or "call by reference" semantics.
Instead, python's model is "call by object". See this writeup for
some

When you call c3.createJoe(c1.fred), you are passing a copy of the
value stored in c1.fred to your function. Python passes function
parameters by value. The function will not destructively modify its
arguments; you must expliticly state your intention to modify an
object:
class one():
fred =

In Python, there are names which are bound to objects. Doing "foo = bar"
and then "foo = s
Why can I not the change the value of a variable in another class,
when I have passed it via a parameter list.
I am sure I am being stupid, but I thought passed objects were Read/

eg
#!/usr/bin/python
class one(): #my Global Var
