I want to learn Python. but I cant decide which application to choose.I don't understand if I should be a Developer, testing or something else which is the future and which is more in demand.

Hello Srinu,
It's good that you have decided to learn the most popular Programming Language. I will suggest you start with the official IDE naming IDLE which you will get with official Python Package. Once you are good with Core Python, you can go for the VS Code, which is the world's best IDE with no doubt.
Whether you want to be a Developer or Tester, it solely depends on your interest. I will suggest you to start learning Python, and you will be self-realizing what to do next.

Hello Srinu, Hope you are doing well!! First learn the basics of Python such as Loops, List, Tuples, Dict and majorly how oops works? I do not think about the role or application. If you become strong enough in basics, then you can decide or become - 1. Developer 2. Tester 3. Ethical hacker 4. Analyst 5. Data Scientist 6. Machine Learning Engineer You can choose jupyter to practice. Code and Have fun.

Dear Srinu, Python is widely used in a number of areas. But, the three main areas where Python is used these days are Web Development, Data Science and Machine Learning. Out of these three areas, Python with Data Science has more demand. Once you learn Python with Data Science, then you can find excellent opportunities in this area. 

Srinu - Python is a language which is used in automation, web development and data science. If you have just begun, then focus on getting a grip on the programming language. The reason is that nearly all companies have a coding test. This coding test is a test of logic.
Once you have a good grip on the language, you can focus on the specialization like web and data science. But the key, as I mentioned, is to have mastery of language first.

Hello Srinu,

First of all, I would like to say that Python is a very versatile technology, and it is a must be add-on in your portfolio irrespective of any career choices. It is very easy to learn and comprehend and opens up a vast portal of opportunities, as you mentioned. Let's talk about these three things, Development, Testing and I am going to consider the "something else" as Data Science.

Testing as a concept is something which is never going to fade away, so we can safely say that it is future proof. You can do a lot when it comes to testing using Python, a whole lot of scripting and automation. Development using Python is not that of a booming market in comparison to Web Development using Python/Django/Flask. If you are into web app development, this could be one of the career options.

Now I am going to talk about Data Science, a field where I belong and meaning to build my career in. Data Science/Machine Learning is something you'll hear a lot these days. This is a field which gradually moves towards the "Artificial Intelligence" zone and is very much future-proof skill you can have in your skillset today. As of now, in India, the demand for Data Scientists is on the rise. However, there are fewer companies that can absorb a fresher, the reason being a lot of companies are not reached to the stage where they can fully leverage Data Science as a sector. But, again as I said, it is very much future proof. So the career path could go something like this, Data Analyst -> Data Scientist -> Machine Learning Engineer -> AI Engineer. So you can start your career with Data Analysis and Visualization and over the course upskill into AI.

I hope this gives you more insight and helps you resolve your confusion.

Thank You!

If you want to learn Python, then learn it. Learn everything in Python. I know it is going to take a few years, but it's ok, after that you will not have this question. That time you will not be a developer or tester or something, you will be considered as an expert, and you can help developer and tester both. :)
Happy Learning!
