Why still in India lot of people are learning Java and .Net etc. We know that Python is in very demand in now-a-days. Recently I came to know that infosys and wipro was not able to undertake a project because it need to be develop in Python (source economictimes). What may be the good way to have a awareness about Python Language?

First lets understand why big companies are still sticking to Java or C or C++. The answer is scalability and reliability. JVM is mission tested for more than 20 years now. Do you know, the client as well as server of Gmail is written in Java? The core algortithms of Facebook are written in Java and C++. You can pick up any company that has scaled and you will realize that the core has been written in Java or C++ or C. Python/PHP/Ruby have scalability issues when you bombard the servers with huge traffic. So where exactly is python used? Its mostly used in writing the logic which doesn't require much of algorithmic computations. For example, Quora's business logic (ie. mostly CRUD operations and some processing logic) is written in python. But the modules that have heavy algorithms and (speed of execution+ memory efficient) are of utmost importance, are written in C++. Also, python is used extensively in Start-ups, where launching your product to market quickly is important.Like, Facebook was initially written in PHP.But as it began to scale, they moved their major computations to C++ and now PHP just acts as an end layer of their stack.They have wrappers all around PHP. So yes, python is important and in high demand. But python isn't going to replace any of the legacy languages. So if somebody wants to learn python, I suggest him/her to first learn either C++ or Java, get your OOPS concepts cleared, understand how programming languages work, and then pick up python. I write code in Python extensively, but I understood python well because my concepts were clear and hence transition was not difficult. But I agree on the point of spreading awareness. That could be done perhaps by conducting seminars/conferences in engineering colleges and if the government decides, then introducing these languages in syllabus would be best solution.
