Guide to Become a Python Developer

In the past few years, the popularity of Python as a programming language has grown exponentially leading to the increase in demand for Python-based jobs in the market. This will bound to lead people to wonder ‘How To Become A Python Developer’. In this blog, I will walk you through the structured approach, career insights, and skills required to become a python developer.
But the question which still lingers is who is a python developer and what are the things that he does. Python being a tool of choice for many things and domains, there is no concrete definition for python developer as such. A Python developer can be a Web developer, Software Engineer, Data Analyst, Data Scientist or an Automation tester, etc. and hence a Python developer can be any one of the above by simply taking the data science with python training.

Python Application
Python has gained a lot of popularity as a programming language since 2018. Ease of access and increased demand is intriguing enough to become a Python developer. The demand caters well for job openings and being the one with the in-demand skills would help you stand out among the crowd. Python programming language has many features that make developers switch to Python over other programming languages. Easy syntax and readability make learning Python a lot easier.

Features Of Python
Google, NASA, IBM, Walt Disney, Netflix, YouTube are a few of the prominent companies that use Python programming language.
A python developer gets paid really well in today’s industry. The range of pay may vary depending on the exact nature of the job they are involved in. You can enroll for any data science with python certification courses available in the market.
Average Annual Salary
Apart from that one can also build this skill set by doing the list of things mentioned below. The list is not exhaustive, but these are some of the common things which we find established python programmers and developers started with.

BUILD YOUR OWN GITHUB REPOSITORY

GitHub is an IT service management organization that provides hosting for software development and version control using Git. GitHub offers its basic services free of charge. Its more advanced professional and enterprise services are commercial. Free GitHub accounts are commonly used to host open-source projects.
As of January 2020, GitHub reports having over 40 million users and more than 100 million repositories (including at least 28 million public repositories), making it the largest host of source code in the world.
Github’s interface is easy and you can quickly learn how to build projects and store it as a repository. Add your Python projects and practice work to your GitHub repository. Even if it is just a simple code you wrote or an existing code that you have made minor changes.
GitHub Repository
Your GitHub repository lends credibility to your resume when you are interviewing for a position as a python developer. Recruiters can look at it on the developer platform instead of you needing to send samples of your work in zip files.
There are many people on GitHub who have unique and organized styles of coding. One of the best ways to develop your coding style is to learn from other Python developers. Look at other codes that are similar to your skill level to get an idea of what different styles are out there.

UNDERSTAND CODING BEST PRACTICES

For the beginners, this may not sound important but this is often not the case. When you display your work, it bears your signature in the way codes are written. One of the important properties of good code is readability and understandability. Experts can very well distinguish okay kinds of codes from the best-written codes and hence this can give a good impression to anyone who is going through your code or trying to understand your work.
It is also seen that most of the python developers often tend to implement coding best practices at some point during the learning curve. So, instead of doing it at a later point in time why not we start this when we begin to learn.
Fortunately, there are guidelines available to help you write readable code, including PEP 8 style guidelines. This guideline can be very handy in starting to build a good set of codes. Some of the important properties mentioned are indentation, tabs, and spaces, maximum line length, line breaks, blank lines, white spaces in expressions, trailing commas, naming convention

READING BOOKS ON PYTHON PROGRAMMING

Even if you are an experienced Python developer, there is always something new to learn. And you will find plenty of new material in Python coding books. The more you know, the more your confidence increases. Some of the good best include ‘Fluent Python’, ‘Python Cookbook’,’Automate the boring stuff with Python’, and ‘Effective Python'.
