Python also provides extensive collection manipulating abilities such as built in containment checking and a generic iteration protocol. Object system. In Python, everything is an object, even classes. Classes, as objects, have a class, which is known as their metaclass. Python also supports multiple inheritance and mixins.
Python's is operator may be used to compare object identities (comparison by reference), and comparisons may be chained—for example, a <= b <= c. Python uses and, or, and not as Boolean operators. Python has a type of expression named a list comprehension, and a more general expression named a generator expression.
Objects are instances of a class. Object-oriented programming ( OOP) is a programming paradigm based on the concept of objects, [1] which can contain data and code: data in the form of fields (often known as attributes or properties ), and code in the form of procedures (often known as methods ). In OOP, computer programs are designed by making ...

Note that, in some contexts, the definition of an "object-oriented programming language" is not exactly the same as that of a "programming language with object-oriented features". For example, C++ is a multi- paradigm language including object-oriented paradigm; [2] however, it is less object-oriented than some other languages such as Python [3 ...

List (abstract data type) In computer science, a list or sequence is collection of items that are finite in number and in a particular order. An instance of a list is a computer representation of the mathematical concept of a tuple or finite sequence. A list may contain the same value more than once, and each occurrence is considered a distinct ...
