Explain the concept of API (Application Programming Interface) and how it can be used to interact with external services or retrieve data in Python.

An API (Application Programming Interface) is a set of rules and protocols that allows different software applications to communicate and interact with each other. It defines the methods and data formats that applications can use to request and exchange information. APIs enable developers to access the functionality of external services, libraries, or frameworks, and retrieve data or perform specific operations. In Python, APIs are commonly used to interact with external services or retrieve data from remote servers. APIs provide a structured and standardized way to make requests and receive responses, typically in a format such as JSON or XML. Here's a step-by-step explanation of how APIs can be used in Python to interact with external services: 1. API Documentation: The first step is to review the documentation of the API you want to use. API documentation provides details on available endpoints, request parameters, authentication methods, an....
