** Python Programming Basics Explored in Article "Day 2 in Python" An article on Dev.to explores the basics of Python programming, focusing on functions and their applications. The article discusses two types of functions: built-in library functions (pre-defined) and user-defined functions. Built-in library functions, such as input() and print(), are pre-existing functions in Python that can be used directly. User-defined functions, on the other hand, allow developers to create custom functions based on their specific needs. The article provides examples of using both types of functions, including a simple calculator function that takes user input and performs arithmetic operations. ** Source: https://dev.to/varatha/day-2-in-python-3m60
