Essential Skills Required for a Python Developer
Python is considered the most modern and advanced programming language. There are specific skills that a Python developer needs in their armoury to carry out the task efficiently. These have been discussed below:
1. Python Fundamentals
In order to have a deeper understanding of Python for web development programming language, let’s discuss its fundamentals in detail:
- Syntax: It refers to a set of rules that governs the interpretation and writing side of Python. The Syntax is easy to understand and follows the principle that “there should be one and only one definite way to do it.”
- Data Types: There are six different kinds of data types in Python: Numeric, Sequence, Boolean, Set, Dictionary and Binary Types.
- Control Flow: Loops, functions and conditional statements regulate the control flow of the Python program. Execution of instruction happens from start to end or from top to bottom.
- Libraries: Libraries are a collection of modules that help the application code perform specific tasks. Panda, Numpy, Keras, Tensor Flow and Scikit Learn are some of the major libraries used in Python.
- Python Packages: Python packages are a way to structure and organise the Python codes into reusable components. Packages serve as a toolbox where you can store and reuse all your functions.
2. HTML and CSS
If you are interested in Python for web development, then you should understand HTML and CSS, as it will help you use Python frameworks like Django and Flask.
- Basics of Front-End Development: As the name suggests, the front-end is that side of the application or software that the customer sees and interacts with. A front-end developer’s primary responsibility is to design the visual components and develop interactive mechanisms like buttons or navigation.
Every front-end developer should have expert knowledge of HTML, i.e., Hyper Text Markup Language. HTML is a common computer language that is useful in developing pages that one can see using the internet. The site designer has to normalise the HTML codes into standard text to save the regular text as an HTML file. A person on the internet views this HTML file.
- Integrating HTML/CSS With Python Frameworks: There are several ways of integrating Python with HTML. The ways have been discussed below:
- Develop HTML with the help of Python frameworks like Django.
- You can also host any app written using the Python codes in the Google App Engine.
- With the help of the HTML Templating Library for Python, the provided HTML can be passed through any web server like Apache.
3. JavaScript
Like Python, JavaScript is also a programming language through which a web developer can execute complex features on web pages such as animated 3D/4D images, structure-wise timely content, and much more. Let’s look at how exactly JavaScript is incorporated:
- Introduction to Client-side Scripting: This is the process through which the client receives a code sent by the server with the HTML web page. The respective code runs on the client’s system while the webpage is still loading or has completed loading. JavaScript is widely used to create innovative, interactive and secure web pages.
- Interfacing with Python Backend: The web developer must send the JavaScript file with user-generated data to the web browser. After that, pick up any Python web framework like Flask, and once it is running, the web developer needs to direct Java XHR requests to the Python server’s domain and server.
4. Version Control With Git
Version control is the process by which one can track all the changes happening in the software code. Git is the most advanced version control system currently in use. Let’s see in detail the different dimensions of Git and GitHub:
- Basics of Git and GitHub: Linus Torvalds, credited with developing Linux OS Kernel, created Git in 2005 as an open-source version control project. Today, many commercial and open-source projects run on Git version control. Git can work on different OS and Integrated Development Environments.
GitHub is a not-for-profit organisation that provides cloud-based Git repository services. These services help store and track changes occurring to software codes.
Best Practices for Collaborative Development and Version Control: Here are some of the best version control practices that one can follow:
- Select a Version Control System
- Follow Branching Strategy
- Take the help of Commit and Descriptive Messages
- Adopt a Code Style and Format
- Execute the Code Review Policy
- Coordinate and Communicate with the Team
5. Backend Development with Python
Python for web development is becoming a go-to tool for backend developers. It allows for the designing and development of innovative and interactive backend solutions. Many web developers are using Python to create potent server-specific components of web applications. Two of them are mentioned below:

- Django: This Python framework simplifies the process of creating complex web applications. With the help of Django, web developers can quickly implement complex tasks like data management, URL routing and authentication.
6. Database Management
Python offers support mechanisms for various database systems. Python answers our queries related to a particular database without writing queries in the terminal. It would suffice if the database is present in the system. Here are a couple of different ways of database management:
- Working With Database in Python: Databases manage data volumes over the web. SQL is a popular query language used in Python. SQLite is a light or easy-to-use version of SQL. SQLite is a public domain, credible, highly flexible and embedded SQL database engine.
- ORM Frameworks Like SQAlchemy: ORM stands for Object Relation Mapper, and SQAlchemy is a Python library that establishes functional communication between a database and a Python program. SQAlchemy functions as an ORM tool that helps translate Python classes into tables of relational databases. SQAlchemy also converts functional calls into different SQL statements.
7. Web APIs and RESTful Services
APIs are a set of rules that developers need to follow to communicate with other software programs. Web developers must create APIs so that various applications can communicate with their applications systemically. Let’s discuss more about consuming APIs using python and REST principles:
- Creating and Consuming APIs Using Python: The complete form of REST is representational state transfer. This architectural style establishes a pattern for interaction between the client and the server. It helps enhance a software’s reliability, simplicity and performance.
- Understanding REST Principles: Some of the major principles on which REST API functions are given below:
- Resource-based Architecture
- Self-descriptive Messages
- HATEOAS
- Statelessness
- Uniform Interface
These principles ensure simplicity, independence between the server and client components and modularity.
8. Testing and Debugging
Testing means the process of identifying any issues or problems in the application. On the other hand, debugging refers to fixing all the errors and problems found in the software. Testing and debugging has more to it, such as:
- Writing Unit Tests for Python Web Applications: Python is an ideal programming language for unit test writing. PyTest, Unittest and Doctest are significant built-in libraries that can perform unit tests.
