Title: Exploring Web Development with Python: A Comprehensive Guide Introduction: Web development has become an integral part of the modern technological landscape, and Python has emerged as a versatile and powerful language for building web applications. In this comprehensive guide, we will delve into the various aspects of web development using Python, exploring frameworks, libraries, and best practices to create dynamic and scalable web applications. I. Understanding the Basics of Web Development: 1.1 HTML, CSS, and JavaScript: Before delving into Python-specific frameworks, it's essential to grasp the fundamentals of web development. HTML provides the structure, CSS adds styling, and JavaScript adds interactivity to web pages. These technologies form the backbone of web development regardless of the programming language used. 1.2 Introduction to Python for Web Development: Python's readability, simplicity, and extensive libraries make it an excellent choice for web development. Familiarizing yourself with basic Python syntax, data structures, and control flow is crucial before diving into web-specific frameworks. II. Python Web Frameworks: 2.1 Flask: Flask is a lightweight and easy-to-use web framework that follows the WSGI (Web Server Gateway Interface) standard. It's ideal for small to medium-sized projects and encourages simplicity and flexibility. We'll explore how to set up a basic Flask application, define routes, and render dynamic templates. 2.2 Django: Django, a high-level web framework, follows the "batteries-included" philosophy, providing a robust set of features out of the box. From database migrations to user authentication, Django simplifies complex tasks and promotes best practices. We'll cover creating a Django project, defining models, and building views and templates. III. Frontend Development with Python: 3.1 JavaScript Integration: While Python handles server-side logic, JavaScript is crucial for client-side interactivity. We'll explore methods to integrate JavaScript frameworks like React or Vue.js into Python-based web applications, allowing for a seamless user experience. 3.2 Template Engines: Python web frameworks often use template engines to dynamically generate HTML. We'll delve into popular template engines like Jinja2, understanding how to create dynamic and reusable templates for rendering data. IV. Database Integration: 4.1 Relational Databases (SQLAlchemy): Python frameworks offer seamless integration with relational databases through libraries like SQLAlchemy. We'll cover database modeling, querying, and migrations, ensuring efficient data storage and retrieval. 4.2 NoSQL Databases (MongoDB with Flask): For projects requiring flexibility in data storage, we'll explore integrating Flask with MongoDB, a popular NoSQL database. This section covers basic CRUD operations and demonstrates the advantages of using a document-oriented database. V. RESTful APIs and Web Services: 5.1 Building RESTful API

Mr. Tim Berners-Lee
created the
World Wide Web

in Geneva, Switzerland.
In 1990 and 1991

6. Definition of Website
A website (also written as web
site)
A collection of web pages and
related content
Identified by a common domain
name
Published on at least one web
server.
wikipedia.org,
google.com,
amazon.com, and etc…

7. Introduction to Web
• A document on the web is called a Web Page.
• A Web page is identified by Uniform Resource Locator
(URL).
• A URL is also commonly referred to as a Web Address.
• A website refers to the location on the internet of the Web
pages and related files.

8. What is Web Development?

9. Definition:
Developing a Web site for
the Internet or an intranet.
Range from developing
A simple single static page of
plain text to
complex web applications,
electronic businesses, and
social network services.

12. Front-end

13. Three Layers of Web Design

14. HTML

15. Do you imagine how
this page would like
without HTML

16. Looks ugly…
Doesn’t it ?

17. No HTML
•Without any markup to give your page content
structure, the browser renders unformatted and
unstyled text.
•HTML Tags give structure and meaning to
your content.

18. Let us Add HTML tags to our
page…
Looks Better….
But still not Good …

19. But What should we do to make
the page look nice ?
The answer is
use CSS….

20. CSS =
Cascading Style Sheet

21. Rules:
Set of rules defining how an html element will be “presented” in the browser.
CSS Rules:
p
{
color: red;
}
#title
{
font-style: italic;
Border: 1px dotted blue;
}
.content {
Font-weight: bold;
Background: yellow;
}

22. Something can and can’t change with CSS:
Can Change
• colors
• font
• font size
• backgrounds
• spacing
• sizes
• borders
• Position(layout)
Can’t change
• content
• Markup

23. After adding CSS to page:
Looks Perfect !

24. Text + HTML + CSS = Web Page

25. Now time for Actions !
Java Script

26. JavaScript is not a Java:
• JavaScript was not developed at Sun Microsystems, the
home of java.
• JavaScript was developed at Netscape in 1995.
• It’s not a light version of Java.
• It was not based on Java.

27. JavaScript:
Classic JavaScript is a
client-side language
used to add interactivity to
your web pages.

28. What can do with JavaScript?

29. What can do with JavaScript?

30. Some JavaScript Frameworks in
Recent Trend:
• Angular JS
• React JS
• Node JS
• Vue JS

31. Back-end
• Python
• MySQL

32. Python:
Now, it's my belief that Python is a lot easier than to teach to students
programming and teach them C or C++ or Java at the same time
because all the details of the languages are so much harder. Other
scripting languages really don't work very well there either.
- Guido van Rossum.

33. Python
• Python is an interpreted, object-oriented, high-level programming
language with dynamic semantics. Its high-level built in data
structures, combined with dynamic typing and dynamic binding.
• One area where Python shines is web development. Python offers
many frameworks to power some of the world’s most popular sites
such as Spotify, Mozilla, Reddit, the Washington Post and Yelp.

34. Python Frameworks:
• A framework is a collection of modules or packages which helps in
writing web applications. While working on frameworks in python
we don’t have to worry about the low level details such as protocols,
sockets or thread management.

35. Operations Involved in
Frameworks:
• Url Routing – Routing is the mechanism of mapping the URL directly
to the code that creates the web page.
• Input form handling and validation – Suppose you have a form which
takes some input, the idea is to validate the data and then save it.
• Output formats with template engine – A template engine allows
the developers to generate desired content types like HTML, XML,
JSON.

36. Operations Involved in
Frameworks:
• Database connection – Database connection configuration and
persistent data manipulation through an ORM.
• Web security – Frameworks give web security against cross-site
request forgery aka CSRF, sql injection, cross-site scripting and other
common malicious attacks.
• Session storage and retrieval – Data stored in the session storage
gets cleared when the page session ends.

37. Classification of Frameworks:
• Full (high-level)
- Come with many pre installed components and lot of low level
task automation.
• Micro (low-level)
- Come with many pre installed components and lot of low level
task automation.

38. Python Frameworks:
• Full (high-level)
• Django
• Web2py
• Turbogears
• Micro (low-level)
• Flask
• Pyramid
• CherryPy
• Bottle.py

39. MySQL:
• MySQL is the most popular database system used in Web
Development.
• MySQL is a database system used on the web.
• MySQL is a database system that runs on a server.
• MySQL is ideal for both small and large applications.
• MySQL is very fast, reliable, and easy to use.
• The data in a MySQL database are stored in tables. A table is a
collection of related data, and it consists of columns and rows.

40. Real-Time Applications:

41. Job Options in Web Development:
• Application Developer.
• Web developer.
• UI/UX Developer.
• Web Content Manager.
