This will allow you to have feedback and recapitulate rapidly. This rapid prototyping makes Python a great language for startups that can hit the industry and have a competitive edge.
Having known about the benefits of Python in web development, let us now discuss the frameworks in Python.
Web Frameworks in Python
A web framework is a collection of modules that includes pre-written codes and standardized codes to help in developing web apps rapidly and easily. The applications developed in Python are a lot more scalable and reliable.
Web frameworks in Python are only used in backend development like aiding URL routing, requests related to HTTP, accessing databases, etc. Web frameworks are recommended by everyone as it helps one in developing complex web applications in significantly less time.
Below are two of the popular frameworks in Python.
- Django
It is a Python web framework that helps in the rapid development of web applications. It is an open-source framework that is rapid, reliable, and scalable. Django offers detailed documentation and vast support from the community. It is incredibly fast and is often used by large-scale companies like Instagram, Dropbox, Pinterest, etc.
- Flask
Flask is considered a micro-groundwork that is sober and lightweight. Flask only provides the components that one needs to create an application in order to have adaptability and control. Flask is prevalent and a powerful framework used by companies like LinkedIn, Uber, Netflix, etc.
These are the top web frameworks used in Python web development. These web frameworks help in creating complex applications rapidly and easily.
Popular Python Libraries in Web Development
There are a lot of Python libraries that are used for effective web development. Every developer must keep a note of it. Here are the Python libraries:
- Scrapy
As a developer, if you need a web crawler for extracting data or information for web applications, then Scrapy is amazing for this. It is an extensively used library used for uncovering patterns, automated testing scraping, and much more.
- Zappa
Zappa is another powerful Python library used for developing an app based on Lambda.
- Requests
It is a popular Python library used for sending HTTP requests quickly. This library is also used to liaise with an app, thereby helping a developer get access to HTML data and pages.
- Dash
Another integral library is Dash. It is used for developing web apps in order to undertake the process of data visualization. Dash is placed on top of Flask and offers features such as pie charts, graphs, bar graphs, dashboards, etc.
Being one of the most popular languages, Python has a lot more to offer than we know. According to developers, Python is the easiest and most widely used programming language. Be it a beginner or a professional - this language is rapid at delivering quality-driven results.
Now that you have an idea about the web frameworks and libraries that Python offers, let us give you a roadmap for developing applications in Python.
Web Development in Python Roadmap
What are the concepts that you must learn in order to learn web development? To make it simpler, here is a roadmap for developing web applications in Python. Have a look!
- HTML + CSS
While beginning with developing web pages, it is important to learn HTML and CSS. These are the two fundamental languages that every developer needs to learn in order to create web pages. It is best to learn how structural responsive pages can help in your app development journey. It will be helpful to acquire knowledge regarding the concepts like HTTP, Browser, DNS, hosting, internet, etc. It is also essential to know CSS frameworks like Bootstrap and Materialize that help in speeding up the process of development.
- JavaScript
Another step is to gain an understanding of JavaScript. It is essential to learn fundamental concepts like controlling statements, variables, string manipulations, arithmetic operators, loops, and much more. After knowing and understanding the fundamentals of JavaScript, it will be easier for the developer to apply JavaScript to different codes associated with the client-servers.
- DOM & jQuery
After having a thorough understanding of JAVA fundamentals and concepts, another thing to learn is the way to manipulate jQuery and DOM to make the creation of web applications easier. By manipulating DOM and jQuery, you will learn to create creative pages and websites.
- Frontend
It is not necessary to learn frontend frameworks like React to create a web application. But it is recommended to do so! It helps in creating beautiful SPAs as well. Often when developers intend to have expertise in the front-end, learning frameworks like React is an additional requirement for recruiters.
- Python
One must know all about Python. Just like JavaScript, one must also know about the manipulation of DOM and jQuery. Understanding the basics will prepare you for working with Django and Flask. Python is an easy-to-learn language and isn't too tricky. The concepts of JAVA and Python are quite the same so there will be no difficulty in learning Python.
- Django + Database
With the help of Django, you will be able to create the right backend environment. Developers need to learn about the databases like SQLite, how to make HTTPS requests/ queries, etc. With the combination of Django and database, one can effectively make a complete web application.
The roadmap is not enough for developers who wish to know more about Python in web development. So, next, we will be discussing how one can create a Python web application. So, let us begin!
How to Create Web Application in Python?
In this section, we will be creating a Flask called the 'Hi Everyone' app. So, here is a step-by-step process for the same!
- Install Flask
The first and foremost thing is to install Flask. pip or pip3 is used depending upon the version of Python that one is using. Here is the code:
Pip install flask
- Flask Application
The next step is to create a flask file called 'hi.py.' Use the given below code:
from flask import Flask
construct =Flask (_name_)
@construct.route ("/")
def hi ();
return 'Hi Everyone!'
If__name__ == "_main_";
construct.run()
This code will run the application and the variable will be initialized. By using these two steps, you will be able to create a flask in Python.
