Why Learn Python?

This tutorial will help you learn Python from scratch, and the concepts discussed in this Python tutorial are easy to understand and provided with illustrative examples. The Python tutorial is well planned to take you gradually from the fundamental concepts like variables, data types to more advanced concepts like inheritance, encapsulation, etc. Hence, if you are stuck somewhere, then you can present your question on the community forum for a convincing answer.

How learning python will help? 

There have been many programming languages in the making; some of them have gone obsolete while others are being continuously used today. The search for an approachable and universal programming language for programmers has shaped the emergence of Python in the landscape of the IT industry. Since its inception, the community of Python programmers has grown, and it has indeed become one of the most highly sought-after programming languages.

In contemporary times, there is hardly any field where the Python language is not being used. Indeed, the market for other programming languages is also going strong. Python is standing toe-to-toe with other technologies like Java, PHP, ASP, etc. Hence, it is understandable why budding and experienced programmers are taking an interest in learning Python. 

The Python Tutorial will help you to have a strong platform of conceptual understandings. You will get the foundation to strive for higher ideals like a Professional Python Certification. Through this Python tutorial, you will also come to know why Python is the most preferred language for machine learning and how the combination with Big Data helps. 

Application and Benefits of Python

1. Machine Learning

Nowadays, algorithms power nearly everything, whether it's search engines, social media, virtual Personal Assistants, or ChatBots. The underlying algorithms are the result of machine learning, which has brought a culture of progressive changes in the technological landscape. Python is the major programming language that has been used for the purpose. It has exclusive libraries only to serve the cause of machine learning.

2. Data Science

A field where Python programming is widely used happens to be Data Science. Professionals engaged in the field of Data Science need to have mastery over the Python language. Python is indeed one of the favorites despite the strong presence of other languages such as R, Java, etc. Python complements the diversity in automation technology along with other frameworks and libraries such as PyBrain, NumPy, etc.

3. Web Development

There are many websites, such as Reddit, which have been developed using the Python language. The principal reason behind the use of Python is its effectiveness and speed. If you compare PHP with Python, you will find that a similar website designed in PHP takes a long time when compared to Python. The presence of frameworks and libraries like Flask and Django make the work much easier.

4. Community

Programmers regularly take help from communities when it comes to resolving programming issues. In these online communities, programmers from all over the world can get in touch to share their experiences and technologies. Therefore, they can update themselves by learning new technicalities on Python and redress the issues they face. 

5. Libraries

When it comes down to the development of websites and applications, libraries turn out to be immensely helpful. It is possible to find any kind of code here. Popular frameworks of Python like Django, Pandas, Keras, Flask, NumPy, and Scipy complement the agile methodology of software development. Libraries provide easy access to the needed code, thus allowing the programmers to maintain their focus on the codes and objectives. 

6. Simplicity

The biggest reason why you need to use Python as the desired language of programming is because of its simplicity. It is user friendly, and beginners can quickly find a foothold to its concepts. Python has an easy and readable syntax that considerably eases out things.

Who Should Learn Python?

If you are having an immense passion for programming, and if you want to see yourself as a successful software developer with proven capabilities, then you must consider learning Python. If ever you want to make your career in Machine learning, Data Science, and Web Development, then you have to master the Python language as it is the programming language of choice these days.

If you’re looking to make a successful career as a programmer in leading IT companies, then learning Python can be a stepping stone for the purpose. Having a certification in Python programming can open up a sea of opportunities for you to cash-in. It is one of the foremost languages that is having applications in different branches of digital electronics like Machine Automation and Machine learning, Data Science, and Web programming. Thus, when you have mastery over the Python language, you can be resourceful to your company by serving in different domains and applications on demand.
