Duck typing In computer programming with object-oriented programming languages, duck typing is a way to write computer code. It doesn't demand that you know what types you are writing about. If it does what you thought it would do, it is good enough. The reason this is called "duck typing" is the duck test. It was invented by James Whitcomb Riley :

Duck typing is when the summer just calls the same methods as before and whatever arguments to the function already have the required methods. You are not adding methods to the argument types just accepting any arguments that have the right methods. -- …

Duck is the common name for numerous species of waterfowl in the family Anatidae.Ducks are generally smaller and shorter-necked than swans and geese, which are members of the same family.Divided among several subfamilies, they are a form taxon; they do not represent a monophyletic group (the group of all descendants of a single common ancestral species), …

鸭子类型（英語： duck typing ）在程序设计中是动态类型的一种风格。 在这种风格中，一个对象有效的语义，不是由继承自特定的类或实现特定的接口，而是由「当前方法和属性的集合」决定。 这个概念的名字来源于由 詹姆斯·惠特科姆·莱利 （ 英语 ： James Whitcomb Riley ） 提出的鸭子测 …

Duck test. A mallard, known a posteriori, both looking like a duck and swimming like a duck. The duck test is a form of abductive reasoning. This is its usual expression: If it looks like a duck, swims like a duck, and quacks like a duck, then it probably is a duck. The test implies that a person can identify an unknown subject by observing ...

A number of different language design decisions have been referred to as evidence of "strong" or "weak" typing. Many of these are more accurately understood as the presence or absence of type safety, memory safety, static type-checking, or dynamic type-checking . "Strong typing" generally refers to use of programming language types in order to ...
