同时,只import module也是推荐的。 The Python documentation also says that it is advisable to use import X, instead of other statements, such as from module import *, or from module import a,b,c. 参考 https://stackabuse.com/python-circular-imports/版权...
import mymixin.py class Main(object, MyMixin): def func1(self, xxx): ... mymixin.py文件: class MyMixin(object): def func2(self: Main, xxx): # <--- note the type hint ... 现在,虽然这样做完全没有问题,但是MyMixin.func2中的类型提示当然无法工作。我不能导入main.py,因为会出现循...
In this tutorial, you'll compare Python's instance methods, class methods, and static methods. You'll gain an understanding of when and how to use each method type to write clear and maintainable object-oriented code.
for me, this is caused by a circular dependency on the type using itself in a type hint within its own definition. i was able to resolve this problem in my scenario by using ForwardRef: CircularObj = typing.ForwardRef('CircularObj') class CircularObj: circular:CircularObj typing.get_type_...

Adding a special __future__ import, which must appear at the beginning of your file, enables the lazy evaluation of type hints. You’ll use this pattern later to avoid the circular reference problem when importing cross-referencing modules. In Python 3.11, you can also use a universal typin...
