Mutable and Immutable Attributes of Classes We have seen how to leverage the differences between mutable and immutable objects and what happens when you use mutable types as default function arguments. However, we haven't discussed what happens when you use mutable types as default attributes of cl...
Mutable and Immutable Objects by David O'Meara Mutable and Immutable objects are a simple idea with wide ranging consequences. Often when immutability is mentioned it isn't defined, or when it is defined there are no details of how to ensure immutability or the consequences. Before we start, ...

If immutable objects are good, simple and offer benefits in concurrent programming why do programmers keep creating mutable objects²? 因为最近在学函数式编程,昨天code review的时候也正好遇到了python的一个deepcopy的问题,所以来翻译下这个回答吧。 mutable和immutable有各自的优缺点,可以看做是safe-efficiency...
Java mutable对象和immutable对象的区别 今天读jdk源码中Map.java时看到⼀句话:great care must be exercised if mutable objects are used as map keys;第⼀次知道mutable对象这个概念,google了⼀下,维基百科定义如下:“In object-oriented and functional programming, an immutable object (unchangeable[1] ...
mutable and immutable objects. 2. immutable objects immutable objects are objects whose state cannot be changed once they are created. once an immutable object is instantiated, its values and properties remain constant throughout its lifetime. let’s explore some examples of built-in immutable ...

In this lesson, you will learn what mutable and immutable objects are, and the difference between them. This understanding will help you determine when objects can be modified in place, and when new objects must be created. List is mutable, which means everytime it returns the same id whethe...
