The first, Foo::new(), is not an instance function and must be specified with the type prefix. The remaining three all take a self parameter in a variety of ways and can be called on a Foo instance using the dot-notation syntax sugar, which is equivalent to calling the type-qualified function name with an explicit self first parameter.
A UML class diagram for a strongly typed identifier. A strongly typed identifier is user-defined data type which serves as an identifier or key that is strongly typed.This is a solution to the "primitive obsession" code smell as mentioned by Martin Fowler.
In Python, functions are first-class objects that can be created and passed around dynamically. Python's limited support for anonymous functions is the lambda construct. An example is the anonymous function which squares its input, called with the argument of 5:
In computer programming, lazy initialization is the tactic of delaying the creation of an object, the calculation of a value, or some other expensive process until the first time it is needed.
In class-based, object-oriented programming, a constructor (abbreviation: ctor) is a special type of function called to create an object.It prepares the new object for use, often accepting arguments that the constructor uses to set required member variables.
