Data descriptors for python module


Data descriptors for python module

it helps some times This cannot be done directly since descriptors need to be defined as class attributes (which mean you'd have to add them to the builtin module type, which is not allowed).
BUT you can just use a simple wrapper around your test_data module and use the __getattr__() magic method:
code :
class DataWrapper(object):
    def __init__(self, module):
        self._module = module

    def __getattr__(self, name):
        val = getattr(self._module, name)
        return copy.deepcopy(val)


from test import test_data
test_data = WrapperData(test_data)

I wish this helpful for you When installing the dependencies for a package you should be using npm install and not using the -g flag.
The g flag, or global is used when installing a package globally, which places them in a direct location that is not accessible by the project.
If all python methods are indeed non-data descriptors can I overwrite a method.__get__?

I think the issue was by ths following , You can't do this by setting A.m.__get__, because the Python language internals skip the instance dict when looking up special methods like __get__. (This is so, for example, a class Foo that defines a __repr__ method uses type.__repr__ instead of Foo.__repr__ when you do repr(Foo).)

like below fixes the issue You can use quotes. Specifying the explicit maven: namespace is also recommended:
code :
import maven:"com.fasterxml.jackson.core:jackson-core" "2.8.4";

I think the issue was by ths following , Disclaimer: I'm the current Redux-ORM maintainer.
There's an amazing blog post series called Practical Redux written by Mark Erikson where he gives a detailed introduction to Redux-ORM. It's a tiny bit outdated but still solid information. But our Readme, mostly written by the original author Tommi Kaikkonen, is also a reliable (and more future-proof) source. We should definitely provide additional step-by-step documentation documentation on a dedicated site. That's mainly a manpower issue.

Hope this helps The override applies to descriptors that are part of the class __dict__.
Python will always look up type(instance).__dict__[attributename].__get__(instance, type(instance)), and will not use instance.__dict__ to search for a instance-override.
