Question

Is it possible to add attributes to a object outside of its scope?

I.e: The following code doesnt works, how do I do what I intended to do with that code?

b = object()
b.foo = "bar"

Answer 1

In general, it is possible. However, it is not possible for most types that are implemented in C, instead of in Python. Unfortunately, this applies to the most often-used of the standard Python interpreter’s built-in types.

If you define a class of your own in Python, you’ll see that it works fine.

class MyObject(object):
    pass

b = MyObject()
b.foo = "bar"
