I think you meant to say:
someAinstance = module_X.A(...)
someAinstance.method_1(...)
If you import module_X in a SINGLE module, in THAT module you could use:
import module_X
class A(module_X.A):
def method_1()...
and create all your instances using A(). (This is the traditional
approach, you modify the original class by inheritance).
Notice that the important thing is where you *create* your instances:
other modules that import module_X but do not create A instances are
unaffected; they will use your modified class anyway.
If you import module_X in several places, and you create A instances in
several places too, you may "monkey-patch" the A class. Somewhere at the
*start* of your application, you can write:
def method_1(self, ...):
... new version of method_1
import module_X
module_X.A.method_1 = method_1
You are effectively replacing the method_1 with another one.
