Static method What about staticmethod? It's pretty similar to classmethod but doesn't take any obligatory parameters (like a class method or instance method does). Let's look at the next use case. We have a date string that we want to validate somehow. This task is also logically bound ...
Class variables and variables in class instances are internally handled as dictionaries of a class object. If a variable name is not found in the dictionary of the current class, the parent classes are searched for it. The += operator modifies the mutable object in-place without creating a ...
