Mutable - Mutable03 flac album

Python handles mutable and immutable objects differently. Immutables are used when you need to ensure that the object you made will always stay the same. Immutable objects are fundamentally expensive to change, because doing so involves creating a copy. Changing mutable objects is cheap  . The above tuple t contains elements of different data types, the first one is an immutable string and the second one is a mutable list. The tuple itself isn’t mutable. it doesn’t have any methods for changing its contents. Likewise, the string is immutable because strings don’t have any mutating methods.

Creating mutable classes. So far, we worked with different type of properties. When we declare stored instance properties with the var keyword, we create a mutable instance property, which means that we can change their values for each new instance we create. When we create an instance of a class that defines many public-stored properties, we create a mutable object, which is an object that can change its state. Creating immutable classes. Mutability is very important in object-oriented programming. In fact, whenever we expose mutable properties, we create a class that will generate mutable instances. However, sometimes a mutable object can become a problem and in certain situations, we want to avoid the objects to change their state. For example, when we work with concurrent code, an object that cannot change its state solves many concurrency problems and avoids potential bugs.

Generally, any custom class is a mutable object. But most importantly, these objects fall under two categories: mutable or immutable. First lets define mutable and immutable: Mutable objects: Could be of types list, dict, set and are objects that can change their state or contents. Generally, any custom class is a mutable object. Immutable objects: Are of built-in types like int, float, bool, string, unicode and tuples and can’t change their state or contents. Although these object types are different they each still hold three similarities. Each object, wether mutable or immutable holds an identity, a type and a value.
