Operator Overloading Operator overloading is an essential process in OOP, which adds multiple functions to the available operators. Operator overloading is the process of extending the predefined function of an operator to user defined functions. For example, the operator + is used to add two i...
“The @overload-decorated definitions are for the benefit of the type checker only, since they will be overwritten by the non-@overload-decorated definition, while the latter is used at runtime but should be ignored by a type checker. ” 翻译过来就是, 被overload装饰的函数仅仅是为了受益于...

Special functions in python are the functions which are used to perform special tasks. These special functions have__as prefix and suffix to their name as we see in__init__()method which is also a special function. Some special functions used for overloading the operators are shown below: ...
Now the+operator in the above code performs subtraction of points. Even though the program works without errors, you should absolutley avoid this. We should always use oeprators appropriately during operator overloading. Similarly, we can overload other operators as well. The special function that...

PEP 484 says that @overload is only allowed in stubs. But if I have a function like this: def plus1(x): return x + 1 then the most precise type is an overload: def plus1(x: int) -> int def plus1(x: float) -> float def plus1(x: complex) -...
