class BaseIndicesLinker: def __init__( self, date: int) @staticmethod def some_static_function(i: int): return datetime.datetime(…) def retrieve_index_codes_from_index_objects(session, date): # converting date to expected datetime format datetime = some_static_function(date) return all_index_codes The above doesn’t work, because some_static_function is ‘not defined’. So I suppose my question is, is it possible to call on the static function without initializing the… Read More Can I call a static method from outside a class without initializing the class?

I have a Base class, and a Derived template that inherits from it. Both of these define a static method calculateSize() but with different method signatures. (Both are also instanced as objects; Base isn’t just an interface.) class Base{ public: static size_t calculateSize(size_t payload); }; template<typename T> class Derived : public Base{ public: // sloppy… Read More Preventing a static method in base class from being called through derived class?

When should I mark the static method of a specific class as private other than public? What aspects should I consider when making such considerations. What are the advantages for mark the static method as private? Any simple example would be appreciated, which could help me fully understand this matter. >Solution : The general rule… Read More When should I mark the static method of a specific class as private other than public?

this is my code which is working fine but it is not correct. I am unable to figure out the problem class MathUtils: @staticmethod def average(a, b): return a + b / 2 print(MathUtils.average(2, 1)) >Solution : you made a tiny mistake – what your code actually does is taking b, dividing it by 2… Read More How this code is failing to give me an accurate answer?

How to check if a method is static given a class, not an instance of a class. In some use cases, the instantiation of a class might have some consequences, and you might need to know if a method is static before any instantiation. Take for example the class: class MyClass: def method(self): pass @staticmethod… Read More Python: check if method is static from class without instantiating

class Circle { constructor() { this.width = 2; this.height = 3; } static area() { return this.width * this.height } } console.log(Circle.area()) // NaN I learned that the static method of Class has this bind to the Class itself, not the Instance’s new object. >Solution : Your constructor binds to an instance of the class.… Read More If ES6's class static method's this binds to the class, why does this return NaN?
