Hi Ranchers,

As per the current market trends ,
How worth is it to learn python?

I am a Java programmer with around 6.5 yrs experience.

Where is python more useful as compared with Java?

Which language can I learn faster Scala, Python, Javascript MEAN stack?
Which one is more worthy of learning compared to Java?  Or should I continue with Java?
Answers are appreciated.

Regards,
-Pankaj.

All of those languages are in use and learning more things is good. If I had to pick one, I'd say learn MEAN becuase Node etc will cause you to grow more. However, it will also likely take you longer to run than Python because Python is more similar to Java.

They're both general purpose programming languages.  I find Python easier to write small apps with since one doesn't need to compile it.

Probably the one that you have a use for.  Are you looking to do some distributed programming?  Scala would probably be better.  Do you want to do web apps?  MEAN would probably fit the bill.  
Personally, I learned Python because I was doing a lot of server scripts and wanted something a more like a "real" programming language than Bash.

Thanks for your help Jeane and Joe,
but which one would be more useful for big data, IOT, Cloud/AI / Cognitive computing?
How about sticking to Java?
Also I don't have strong mathematical background, so what will better for mee?
Big Data/IOT/Cloud/AI/Cognitive computing?

Regards,

Those are completely different things. What do you find interesting about each one?

IOT is built on top of the existing internet architecture, so it is no surprise to see general-purpose programming languages (Java, C, C++, Javascript, Python) scoring high in surveys of IOT languages.  The language you use should probably be dictated by whatever IOT platform and hardware you choose to work with.  Note that different projects may require different platforms/languages.
Cognitive computing (disclaimer: I have no first-hand knowledge of this domain) appears to be well supported by those same general purpose languages as well as some niche languages (i.e. LISP, Go, RUST, Haskell, Prolog, etc.).  Your best bet in this case would be to locate a researcher or community that is doing work you find interesting and look into whatever tools they recommend so you can converse knowledgeably and build off of what they've done.
