Here's a type variable in a normal method. This works fine: fromtypingimportTypeVar,GenericT=TypeVar('T')classA(Generic[T]):deff(self)->None:x:T However in a static method this doesn't make sense, since we don't have an instance ofAto provide any parameterized type forT: ...
Note: You can name your inner function whatever you want, and a generic name like wrapper() is usually okay. You’ll see a lot of decorators in this tutorial. To keep them apart, you’ll name the inner function with the same name as the decorator but with a wrapper_ prefix....
