A Complete Guide To Python Full Stack Tutorial
Python has risen to the top of the list of programming languages used globally in less than ten years. It’s utilized by well-known corporations like Facebook and Google, and newbies will find it to be very user-friendly and versatile. Python is a potent programming language, as we all know. You might not be aware, though, that it can also be used to build full-stack web apps. Still, yes!Â
Python is a programming language that may be used for data research, machine learning, front-end development, and other things. Back-end, front-end, and full-stack developers are the three main job titles in the Python world. A front-end developer is in charge of how the data appears to users, whereas a back-end developer works with the logic and flow of the data. Â
A Python full-stack developer’s job is to act as an interface between these two positions. In both the front-end and back-end components of an application, they are responsible for streamlining the user experience. Full-stack Python development has the potential to be a very lucrative career choice, but it can also be fairly challenging.
What is Python?
Python is an advanced object-oriented programming language. Because of its simplicity and adaptability, Python is preferred by most beginners in the programming profession as one of their primary languages to learn. Additionally, it enjoys strong community support and maintains a steady level of popularity. We will master the fundamentals of Python as a programming language and comprehend how to get started with it in this beginner’s Python tutorial. We’ll go over downloading and installing Python and using well-known IDEs to get started coding. We’ll go into great detail on Jupyter features as well.
Why Learn Python?
One of the most well-liked programming languages in the world is routinely regarded as Python. Python is quite simple to learn, so if you’re just getting started with learning a programming language, Python can be a perfect option. Python is now being taught as the main programming language at many different schools, colleges, and universities. The following are just a few more excellent reasons why Python is every programmer’s first choice:
- Python is available for free because it is open-source.
- It's very basic and simple to learn Python.
- Python is adaptable and may be used to make a wide variety of things.
- AI, ML, and other strong development libraries are available in Python.
- Python is in high demand and guarantees good compensation.
Students as well as professionals who want to become exceptional software engineers, especially those in the web development field, MUST learn Python. The following are some of the main benefits of learning Python:
Python is Interpreted — The interpreter processes Python at runtime. Your program does not need to be compiled before running. This is comparable to PHP and PERL.
Python is Interactive — You can use a Python prompt to directly communicate with the interpreter as you create programs.
Python is object-oriented because it allows object-oriented programming, which encapsulates code inside objects.
Python is a terrific Language for Newbie Programmers and facilitates the creation of a variety of programs, including simple text editors, web browsers, and games.
Front-end Development with Python
The term “front-end development” describes the process of creating application components that users interact with, primarily web interfaces. The work of front-end engineers is sometimes mistaken for web design since creating web interfaces is a visually oriented process. Although there are many parallels, front-end developers play a far more sophisticated function. They use potent JavaScript libraries like Angular or React to create asynchronous code that executes on the browser side to create intricate and dynamic front-end features.Â
Until recently, Python’s front-end support lagged behind that of other programming languages like JavaScript. But Python is now just as adaptable as JavaScript due to the recent emergence of front-end frameworks like Anvil, Brython, and Skulpt. Let’s quickly examine each of these in detail:
Skulpt
Yes, that is how this library is spelled; it is not a typo.
Skulpt is a comprehensive Python in-browser runtime that works with Python 3.
Skulpt is undoubtedly actively being developed, which is no small accomplishment. Some of these “out-there” ventures have potential, but their inventors abandon them because they gain no traction.
Skulpt has been a work in progress for the past five years, and its most recent commit was made less than a week ago, according to a cursory glance at its repository.
Brython
A web-based version of Python 3 is called Brython. Similar to Skulpt, it runs directly in the browser, although it takes a somewhat different approach.
It appears that the Brython package is transpiring Python into JavaScript rather than having a runtime written in JavaScript. This gives you direct access to the DOM through the language’s expanded API (since Python, of course, has no concept of DOM).
Anvil
Last but not least, let’s talk about Anvil, which may be seen as the culmination of both Brython and Skulpt.
Anvil is essentially a complete web application development environment where Python is the sole language allowed for both the back-end & front-end code. Additionally, it self-hosts your applications and gives you the option to design the user interface (UI) using drag-and-drop tools.
For your front-end requirements, Anvil offers Python 3.7, which, like Brython, is translated into JavaScript.
You can even use a built-in Postgres database without the need to set anything up because of them.
Back-end Development with Python
Python backend programming is excellent at supporting server-side features of web applications. The backend is responsible for managing data storage, retrieval, and formatting in a format that is recognized by other applications. For example, data is stored locally so it can be analyzed and understood by other programs over HTTP connections. As a result, the backend needs to be able to parse an HTTP request and comprehend its contents before performing the necessary operations on it, which include actions like storing, updating, validating, deleting, and retrieving.
One approach to using these two features to develop applications is to store HTML, CSS, and JavaScript on the server, generate templates using databases, fill them with data, and then deliver them to browsers through networks. anything that operates without a hitch in smaller applications but could materially impair performance in bigger ones.
This can be done, for example, by having web servers deliver data in a certain format, which front-end developers can then read and use JavaScript to display through templates on the front end. This speeds up the work overall and decreases server processing.
Python backend development is made efficient by employing several libraries. We’ll examine a couple of them in depth:
Flask and Django
Open-source web development frameworks based on Python called Flask and Django are both made to make coding simpler for developers. While Flask is a well-known micro-framework that is lightweight but adaptable, Django is a full-stack framework.
 Because it relies on outside libraries very little to none, Flask is referred to as a micro-framework. It gives developers the freedom to select the design patterns, databases, and tools they want. The primary characteristic of this Python framework is therefore flexibility.
Flask’s popularity is constantly growing as a result of the web development industry’s current inclination towards micro-services and serverless platforms. It is frequently used to quickly construct scalable web applications.
Django is a full-stack framework whose main objective is to simplify the creation of difficult database-driven websites. By relieving developers of tedious web development activities, it promotes secure and quicker development. It gives developers the tools they need to make strong, high-performing apps thanks to its many fantastic features.
The Django framework’s ease of scaling and security make it an excellent choice for creating enterprise-level applications, which is another one of its USPs. Django eliminates the need to start from scratch by supporting a variety of formats (including XML, HTML, JSON, etc.), allowing developers to concentrate on creating the business logic for the web apps.
Robot Framework
Robot Framework is an open-source framework for automated testing used in acceptance testing and test-driven development. It uses a variety of test case writing techniques, including keyword-driven, behavior-driven, and data-driven styles. It is really simple to comprehend because of this characteristic.Â
In a tabular structure, test cases are written using a keyword style. The open source, external libraries, and technologies that can be utilized for automation are well supported by the Robot Framework. The Selenium Library, which is used for web development and UI testing, is the most widely used library with Robot Framework. It employs a keyword-driven testing technology method, and testing libraries written in Python or Java can be used to expand its capabilities.
