I have opportunity to study either JAVA or PYTHON.
But I can't decide which to choose. I am already well versed with C++.
Can you plz tell which one is better with our experience.
Start out with Python; use Python for your own hackish projects - it's great for Web Apps and rapid prototyping.
Learn Java later on and you'll enjoy it; learn it before Python and you won't appreciate the kind of OOP Java has to offer as much.
This is from personal experience; again, like twodayslate mentioned, there is no "right" answer. I learnt both Python and Java on my own and use mainly Python for personal projects.
Which to choose Python or java
