THIS ARTICLE ABOUT REQUEST METHOD:
In data science, the requests library in Python is a commonly used library for web scraping. The requests library allows you to send HTTP requests to a website and retrieve the HTML content of the website for further processing. The most common request method used in web scraping is the GET method, which retrieves data from a website.
Requests library works when data scraps through API from any web side.
Here are the steps to perform web scraping with the requests library in Python:
1.?Install the requests library in Python using pip or another package manager.

6.?Use parsing libraries to parse the HTML content and extract the data you want.
7.?Store the extracted data in a structured format, such as a Pandas dataframe, for further analysis and manipulation.
8.?Repeat the process as needed to extract additional data from the website or other websites.
API:
API stands for Application Programming Interface. API is a set of protocols and tools for building software applications and integrating different systems. It defines the way that different components of a system should interact, allowing for communication and data exchange between them.
JSON:
JSON (JavaScript Object Notation) is a lightweight data interchange format that is widely used in web development and data science. It is a text-based format that uses human-readable text to transmit data objects consisting of key-value pairs. JSON is often used to transmit data between a server and a web application, or between different systems, as an alternative to XML.
