What is the Application of Python?
Ok! Now you have a general idea of what Python is, who should learn it and why it’s a good idea to start learning.
Python is easier to learn and use than many other coding languages. Its functions can be performed with simpler commands and with less text than other competitive languages. This may explain why it is growing in popularity with developers, coding students, and the tech industry.
Due to Python’s accessible and versatile nature, it is now among the world’s top five most popular languages. Many other organisations use Python to achieve their functionality, including YouTube, BitTorrent, DropBox, Wikipedia, Google (where Van Rossum worked), Yahoo!, CERN, and NASA.
The following are the Pythons primary use:
1. Web Development
One of Python’s main applications is scripting, helping to build websites and web applications. You can make web-applications at a rapid rate in Python. It is possible because of the frameworks, such as Pyramid, Django, and Flask is used in Python to create these applications.
On the other hand, Python is used to write the Back-End part of the application, which is the application’s behind-the-scenes functionality. It is an important part that powers all the application functionality but that you don’t see the codes directly on the screen.
Python also manages the server-side of the application when the user requests data. It interacts with all the necessary databases and returns the requested data to the user to run the application as expected.
2. Scientific Computing & Data Science & Machine Learning
Nowadays, the use of Python in the field of scientific computing and data science has increased significantly. There are several science-friendly or science-specific libraries in Python. Below are some examples of science-specific libraries:
- AstroPy for astronomy
- BioPython for biology and bioinformatics
- Graph-Tool for statistical analysis of graphs
- PsychoPy for neuroscience and experimental psychology
Well, if data science is not science enough for you, you can learn Machine Learning using Python. Python is also a significant language for machine learning, which is a tech field focused on artificial intelligence. Python’s machine learning libraries and frameworks are scikit-learn and TensorFlow.
Start-ups, especially tech company start-ups, prefer Python. Because it’s easy to use and scale across an entire company, this means that they can use Python to create a digital product that works for a handful of people. If the customer base grows to hundreds or thousands or even millions, the service provider can still update and maintain it. Also, the time required to learn Python style coding is very little compared to other popular languages, like C, C+.
4. The Financial Industry
Nowadays, Python is becoming increasingly popular for its potential applications in the financial industry. Well, the reason for this soaring popularity is Python’s usefulness in applications such as data regulation, analytics, risk management, and quantitative rate problems. Furthermore, there are many Python tools available that make it the perfect language for fintech and other finance applications. The following are a few examples of Python in the financial industry:

You need to be very self-disciplined and motivated to learn through online courses. Keep in mind that not having a deadline or due dates can make it very hard to move forward, so make sure you remember it.
Step 4: Install Python on Your Computer
Python 2 and 3 are the two main versions of Python software. That means that you have to choose the right one for your own needs.
You need to install the python software if you want to use it with the Windows operating system. Apple computers do not need to install Python because they come with pre-installed Python software.
Installing Python on Windows Computer:
To install Python on your Windows computer, you will need to go to the Python downloads page. You will notice there are hundreds of different versions available in there. Download the latest version to learn the language and get familiar with its main syntax. Follow the prompts on your computer and install Python just like you would any other program.

- Online Forums
Step 6: Discover Python Frameworks
Frameworks are programs that are specifically designed to make your life easier as a coder. Most of the Python frameworks are originally built for web development. These frameworks can be used to help you develop web applications faster. It also makes sure your code follows the best practices and gives you more time to focus on your work.
You should start getting familiar with the frameworks if you are serious about becoming a Python developer. The following are some of the most popular Python frameworks:
Django is an open-source, free, full-stack web development framework. The aim of the framework is to provide developers with everything they need instead of relying on libraries. For this reason, developers throughout the world use this framework.
Flask is a smaller web development framework. It is designed to help you create a high-quality web app foundation for your website. It allows you to use extensions, where necessary in web developing.
Pyramid is almost similar to Django, but it focuses on simplicity and ease of use in web developing. The framework is compatible with applications of any size, which makes it popular among developers across the world.
These are only a few of the most common Python frameworks among others. While you’re learning Python, you don’t need to learn every feature of all of the most common frameworks. You need to make sure that you’re familiar with them, instead of learning all the framework features. For instance, what they are used for, and what are their main features.
Step 7: Start Your Projects
As of now, you should have figured out the best way to learn Python for your needs. You should also have a pretty good knowledge of Python basics and begin to understand how to create a program on Python. From here, the best thing is to do is start practising your coding skills.
Well, the way to learn Python is by practising what you already know by writing your programs. In Python, creating a simple program is easy. You don’t worry about trying to write the next best-selling piece of software or game; instead, you should focus on writing a simple programme. You should follow these steps to guide you when you first start writing the project:
- Brainstorm new ideas and concepts for your first simple Python programs. Write the new ideas down on some paper or note. From there, choose a few that seem interesting to you, and you think you can and have the knowledge to create the programme.
- The next is to start writing code for your program. Make sure that you test it in every step as you go. By doing this, you would have picked up on mistakes before they become major problems. You might find it helpful if you make and write a short plan detailing the necessary steps you need to take to write your program.
- After you have finished writing the programme, go through it. You need to make sure you have notes about what you did and why. You can post your code on an online forum and ask people to critique it for you.
Your first program will not be anything special, be prepared to receive lots of negative comments. But make sure that you take notes of this feedback and use it to improve your next program.
Step 8: Make Sure You Understand Error Codes
You should also take a crash course on Python error codes while you are learning Python. We believe that understanding error codes is a major part to learn Python. If you do not know the meaning of a specific error or how to fix it, you will not be able to fix any code effectively.
You should spend at least a few hours familiarising yourself with the common Python errors. Visit Python website for a full list of error types and learn how you can solve them independently.
Step 9: Keep working on harder projects and challenge yourself every day
To be a pro Python coder, you need to make sure that you are continuously improving your coding skills. If you feel comfortable about what you are building, increase the projects’ difficulty level and scope. There are different ways to challenge yourself every day.
Here is some challenge you can take to improve your coding skills:
- Help a beginner to build a project that you made.
- Improve your tool to work with more data, or can it handle more traffic?
- Make your program run faster.
- Make your tool useful for more people.
- How would you market the tool?
