Python is a widely used high-level programming language for general-purpose programming, created by Guido van Rossum and first released in 1991. An interpreted language, Python has a design philosophy that emphasizes code readability (notably using whitespace indentation to delimit code blocks rather than curly brackets or keywords), and a syntax that allows programmers to express concepts in fewer lines of code than might be used in languages such as C++ or Java.The language provides constructs intended to enable writing clear programs on both a small and large scale.
Web development is the umbrella term for conceptualizing, creating, deploying and operating web applications and application programming interfaces for the web.
Why is web development important?
The Web has grown a mindboggling amount in the number of sites, users and implementation capabilities since the first website went live in 1989. Web development is the concept that encompasses all the activities involved with websites and web applications.
How does Python fit into web development?
Python can be used to build server-side web applications. While a web framework is not required to build web apps, it’s rare that developers would not use existing open source libraries to speed up their progress in getting their application working.
Web Development Resources
While not Python-specific, Mozilla put together a Learning the Web tutorial for beginners and intermediate web users who want to build websites. It’s worth a look for general web development learning.
The Evolution of the Web visualizes how web browsers and related technologies have changed over time as well as the overall growth of the Internet in the amount of data transferred. Note that the visualization unfortunately stops around the beginning of 2013 but it’s a good way to explore what happened in the first 24 years.
Web development involves HTTP communication between the server, hosting a website or web application, and the client, a web browser. Knowing how web browsers works is important as a developer, so take a look at this article on what’s in a web browser.
Three takeaways for web developers after two weeks of painfully slow Internet is a must-read for every web developer. Not everyone has fast Internet service, whether because they are in a remote part of the world or they’re just in a subway tunnel. Optimizing sites so they work in those situations is important for keeping your users happy.
Python is a favourite among many developers for its strong emphasis on readability and efficiency, especially when compared to other languages like Java, PHP, or C++.Sure, it’s old, but it’s 1980s old, not Cobol or Fortran old. Besides, if something works, why change it, especially when there are a so many ways to improve it. Actually, depending on how you view it, longevity is a good thing in itself—a sign of stability and reliability.
If you’re like many people who first started out with Java, C, or Perl, the learning curve for Python is practically nonexistent. But the fact that it’s easy to learn is also the reason why some people don’t see Python as a necessary programming skill. Whether you’re starting a new company, or looking for a language to help you land a job, Python can and will push you to great heights.
What is a web framework?
Before we get into the why let us first understand what a web framework really is.A web framework is nothing but a collection of packages and modules that allows easier development of websites. It handles all low-level communication within the system and hides it from you to make no issues for performing common tasks for the development.
The line where it draws the line between which to hide and which to not, depends on the individual framework itself (more on this later).
Why choose a Python web framework?
You can always create a web application from scratch, but there are various reasons you would not want to. Below are the top five reasons why you should choose Python framework over your own.
Used and trusted by many large companies
Popular Python frameworks like Pyramid and Django are used by companies like Bitbucket, Pinterest, Instagram and Dropbox in their web application development. So, it is safe to say these frameworks are able to handle almost everything you throw at them.
Hides complicated low-level details
As stated above, web frameworks are meant to hide and handle all low-level details so that you as a developer, do not have to dig deep into how everything works when you are developing a web-enabled application.
Saves your valuable time
The frameworks have been built investing thousands of developer and testing hours. Building on top of it saves your valuable time. Especially, when you are developing a simple prototype of a website or are closer to a deadline, using web frameworks can turn out to be a life safer.
One of the most important advantages of using a web framework as opposed to building something on your own is handling the security of your website. Since web frameworks have been used and backed by thousands, it inherently handles security, preventing any misuse of the web application.
Efficient and scalable system
Good frameworks are built ensuring scalability from the very beginning of the development process. So, whenever you are planning to scale your website by adding a new component or using a new database, web frameworks are more likely to scale better than what you come up with when building from scratch.
Which framework to choose?
There are tons of Python web frameworks, and every framework has their own strengths and weaknesses. Thus, it is necessary to evaluate your project requirements and pick one the best one from the collection.
Below are the three most popular web frameworks in Python.
Dextra technologies is probably the most popular Python web framework and is aimed mostly at larger applications. It takes a “batteries-included” approach and contains everything needed for web development bundled with the framework itself. So, you do not have to handle things like database administration, templating, routing, authentication and so on. With fairly less code, you can create great applications with Dextra technologies.
