But this is only works with Python 3.7 or above. And then, just use type(QObject) instead of sip.wrappertype: # -*- coding: utf-8 -*- from abc import abstractmethod, ABC, ABCMeta from typing import TypeVar, Generic, Iterator from PyQt5.QtCore import QObject from PyQt5....

Or should I start a discussion on python-ideas or on discourse? For my use case, in metadsl, I need to be able to compute the return type of a function given some arguments. I am able to do this currently using the existing runtime hooks, but it would be better if I knew I was...

While it is relatively easy to add support for modules in a JavaScript library that revolves around only one object, MooTools provides several global variables such as Class, Events, Type (Native) etc. In addition to that this new standard is very young and if we ever implement support for...

Thanks Morgan, I missed that! This is quite a complex scenario: GFK, PK type mismatch, and MTI so I'm not surprised it broke given the small number of tests for PK type coercion. The culprit seems to be that related fields don't delegateto_pythonto the field they reference so theOthe...
归功于 python 的 数据类型 data model, 你的用户自定义类型的行为可以像 built-in 类型一样自然。 这并不需要通过继承 inheritance 来获得. 本着 duck typing, 可以在对象中只实现需要的方法, 就能 保证保证对象的行为符合预期. 对 Python 来说,这基本上是指避免使用 isinstance 检查对象的类, ...
