copy object?
 

Hello

I am new to python and have some questions.

How to copy objects using another method than this:

class op:
def __init__(self, op):
for x in dir(op):
if x[:2] == "__":
continue
setattr(self, x, getattr(op, x))

o = op(src)

I tried to copy with "o = copy.copy(src)" but as soon as "src" is
gone, "o"'s attributes are not correct, and I cannot use copy.deepcopy
() because of this error:
TypeError: object.__new__(SwigPyObject) is not safe, use
SwigPyObject.__new__()

Can the previous for loop be simplified and replaced with a map() and
a lambda function?

Thanks.

What do you expect op to be? Certainly not the class 'op'.

If you want the instance to be a copy of another instance, the easier
place to make the copy would be in the __new__ method, where you might
be able to use copy.copy.
