HTML forms the structural foundation of a webpage. It defines the content and its organization, using tags to specify headings, paragraphs, images, links, and other elements. Here's an example of a simple HTML code snippet:

  <!DOCTYPE html>
  <html>
   <head>
    <title>
     My Web Page
    </title>
   </head>
   <body>
    <h1>
     Welcome to my website!
    </h1>
    <p>
     This is a paragraph of text.
    </p>
   </body>
  </html>

from flask import Flask

app = Flask(__name__)

@app.route("/")
def index():
  return "Hello, world!"

if __name__ == "__main__":
  app.run(debug=True)

2.2.2 Databases

Databases store and manage the data that powers web applications. Popular database systems include MySQL, PostgreSQL, MongoDB, and SQLite. They provide methods for storing, retrieving, and manipulating data efficiently.

2.2.3 APIs (Application Programming Interfaces)

APIs act as intermediaries between different applications, allowing them to communicate and share data. For example, a weather app might use an API to fetch real-time weather data from a weather service provider.

2.3 Other Essential Areas
