Python offers itself not only as a popular scripting language, but also supports the object-oriented programming paradigm. Classes in Python describe data and provide methods to manipulate that data, all encompassed under a single object. Furthermore, classes allow for abstraction by separating concrete implementation details from abstract representations of data. Code utilizing classes is generally … Read more

Metaclasses in Python allow you to deeply modify the behaviour of Python classes (in terms of how they’re defined, instantiated, accessed, and more) by replacing the type metaclass that new classes use by default.
