To become a successful developer, a basic understanding of programming, computer science concepts, user interface design, web development, and project management is essential. This knowledge might help you better understand the projects that companies undertake every day in this field and what they may require from you before offering you a job position. Learning more about Python developers and how you can follow this career path may help you better evaluate this professional field and understand if this is a good choice for you.
In this article, we discuss what a Python developer is, explain how to become one, and list the essential skills you can develop to excel in this career.
What is a Python developer?
A Python developer is a computer programmer who specializes in the Python programming language, which means they use it to create software, build websites, automate tasks, and perform data analysis. Python is an object-oriented language that a professional can use for specific or general purposes. Object-oriented means that the language organizes code into objects or data, instead of organizing code into logic and functions. These developers can work in virtually any industry because software development can be essential to any business.
For instance, they might create finance analytics tools and mobile banking applications, which enable them to work in chartered banks and investment firms. They can also create cryptocurrency trading tools, algorithms related to the stock market and trading systems, and social media apps. These professionals can work in the gaming industry because they're experts in developing game apps and machine learning applications. They often use other object-oriented programming languages to complement Python.
How to become a Python developer
Here are five simple steps on how to follow this professional path:
1. Become a developer
Although advisable, to become a developer, it's not necessary to get an undergraduate degree in fields such as computer science or math. You can become a developer by taking courses in programming languages, completing several exercises in a coding bootcamp, or by learning to code by yourself. You can do this by enrolling in online courses, attending a short course offered by a local college or university, or by participating in a virtual community of developers. You can also buy books and videos to learn how to code, which allows you to advance at your own pace.
2. Learn about Python
Next, it's crucial to learn how to use Python to apply it as the main programming language for your development projects. You can do this by enrolling in a specialized course, reading several books on the subject, and practising with a variety of Python tutorials. You can also find helpful online free resources that might explain to you how to develop a web-based application with Python from the beginning. These resources can be very helpful because they can provide you with a step-by-step guide and a forum where you can ask questions and discuss the project with other developers.
3. Develop a basic app with Python
After learning Python, it's crucial to start using it and find a project you wish to complete. It's advisable to start with a project that requires a basic knowledge of Python, such as a web scraper, calculator app, or password generator. Other applications you can develop at this stage include a to-do list, alarm clock, uniform resource locator (URL) shortener, dice roll generator, or online survey.
During this step, it's also beneficial to look for a mentor who can guide you and help you complete the project, particularly if they can answer any questions you have about the language. You can find a good mentor by looking online in forums or online communities, visiting your local college, and asking your colleagues. When choosing a mentor, make sure they're experts in the language, understand other object-oriented programming languages, and are eager to help.
4. Get a certification
One of the best ways to test and officialize your recently learned Python skills is to get a certification that requires an examination. Getting an accreditation can help you showcase your skills to potential employers, enhance your resume and cover letter when applying for a job, and give you a sense of accomplishment. There are several online and in-person certifications you can pursue to validate your Python skills, each of them with different benefits and requirements.
If you didn't attend a university program to get your Python proficiency, you might look for certifications that don't require a bachelor's degree. To earn a certification, you typically complete a complex project where you can demonstrate your expertise and level of knowledge. Other certifications might just require an examination that covers the material in the certification.
5. Find a job
Finally, it's important to look for a job position where you can use your Python abilities. Evaluate in what industry you want to work, as this usually depends on your level of expertise. For instance, the gaming industry might require you a high level of Python programming skills because the complexity of the games increases with each new release.
Regardless of the industry, you can start by looking on job boards or websites for entry-level positions that require Python programming skills. If you get a job offer, it's important for you to learn from more experienced developers. This may include front-end, back-end, and full-stack developers who can teach you how to code complex applications and algorithms.
Here are three essential skills that can help you succeed in your developer role:
Proficiency in debugging
Debugging is the process of finding and fixing coding errors in a software program. This is a basic skill you learn in any programming class and is essential for any software development project. This ability also requires you to have excellent attention to detail skills, as you might spend hours reading and reviewing code looking for errors.
A good exercise to develop your debugging skills is to review the code of malfunctioning programs or help analyze code written by other developers. You can become an expert debugger and find job positions in the gaming industry where this role is highly valuable.
Expertise in testing procedures
Testing applications can help you understand the strengths and weaknesses of a computer program. There are several types of testing you can perform and several apps and techniques you can use to complete these tests. By testing a program, you review its user interface (UI), the features it offers, the logic and functions that support the application, and the overall usability of the program.
These skills can help you decide whether a computer program is ready for release to the public or if it needs more improvements. This is a specialized skill that all employers look for in prospective developers.
Knowledgeable in database
As Python is an object-oriented language, it has excellent database features. It can support various types of databases, such as MySQL, Oracle, and SQLite. Becoming an expert in databases can help you create more complex applications and adapt to the different databases that companies use to develop their software.
A database is a collection of data that follows a precise order and is accessible by a specific electronic program. Usually, applications use databases to store data they collect from users, such as contact information. Having these skills allows you to work in different industries, especially if you want to build websites and mobile apps.
Proficient in algorithms
You can improve your maths skills by specializing in algorithms. As programming involves creating algorithms to develop applications and these algorithms are the core of their code, it's crucial for you to have a good understanding of these math tools. You can improve your math skills by looking for online resources such as courses, books, and exercises.
