A programming paradigm is a style of reasoning about programming problems. Problems, in general, can often be solved in multiple ways; for example, to calculate the sum of 2 and 3, you can use a calculator, you can use your fingers, you can use a tally mark, and so on. Similarly, in programming, you can solve problems in different ways.
At the beginning of this book, we mentioned that Python is multi-paradigm, as it supports solving problems in a functional, imperative, procedural, and object-oriented way. In this chapter, we will be diving into object-oriented programming in Python.
