Duck Type in Python 在程序设计中,鸭子类型(英语:duck typing)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 “当看到一只鸟走起来像鸭子、游泳起来像鸭子、叫起来也像鸭子,那么这只鸟就可以被称为鸭子。” 就我个人的理解来看...
Duck typing is a term used to describe the polymorphic behavior of objects in dynamically typed programming languages like Python. This principle allows an action to be taken depending on the type of built-in objects being processed. It doesn’t care that an object is a duck, it only cares...

Duck typing is a variation of Dynamic Programming and uses a form of abductive reasoning for type checking. In this article, we will focus on the main intuition of duck typing and examples of ducking typing in python. What is Duck Typing in Python? – Abductive Reasoning The term duck argua...
Python术语表中的鸭子类型duck-typing: A programming style which does not look at an object’s type to determine if it has the right interface; instead, the method or attribute is simply called or used (“If it looks like a duck and quacks like a duck, it must be a duck.”) By empha...
Many functions in Python also require strings and "string" is defined as "an object which inherits from the str class".For example the string join method accept iterables of strings, not just iterables of any type of object:>>> class MyString: ... def __init__(self, value): ......
