Object Oriented Programming Flashcards
What is object oriented programming?
Programming with the view of objects rather than just sequential patterns. This allows us to program more efficiently than if we had just plain variables.
What is a class?
A class is a template or blueprint that allows to create objects. In a class, we usually have multiple methods. Furthermore, it allows us to keep multiple methods in one place if it pertains to the same type of object.
What is a method?
A method is similar to a function that operates on a object of a class. Specifically, it can help us operate on an attribute of a created object.
What’s an attribute?
An attribute is a descriptor/characteristic for an object in a class. It’s usually assigned to the object in the constructor.
What is a constructor?
A constructor is what assigns attributes to an object. It allows us to create objects. Another term for constructor is the initializer which, like in the name, requires for us to initialize the objects in the class.
What’s another way to express that a variable, x, is a object of a class?
Another way to say it’s an object of a class is to say it’s an instance of a class.
What is an object?
An object is something that has attributes and usually methods. It’s created via a class.
What is the difference between a function and a method?
A method is a function that operates on an object of a class, while a function is a standalone operator that is not restricted to operating on a object. A function is defined globally while a method is defined and restricted to it’s class.
What are **kwargs?
It’s an acronym that stands for:
[ K ]ey [ w ]ord [ arg ]uments
It allows us to provide any number of arguments. **kwargs are not limited to being used in object oriented programming.
What’s the benefit of using a built in string method compared to a manually created one?
It allows us to access the functionality of the string method by using the print function automatically.
