python variable assignement

[mihai]

I work at an application witch has embeded python.

We have an python type X.

# a != b

a = b # at this point both variables have the same value

b = select_other()

# steel the same values but both have the new value of b

What might be the cause for this behavior? The type of a and b
variable is the same,
and is defined using PyTypeObject structure.

I hope I was explicit.

Thank you in advance,
Mihai.
