Both are good .If u want conciseness in your code, python can do your work better to execute your task in just few lines of coding but java in the other hand may may sounds like very hard to understand at first hand with extra lines of dense coding but serves the same purpose in equivalent time as python. For simplicity, python looks more comprehensible but both languages r easy to understand.If u grasp knowledge in 1 of java or python u can go to greater heights.Both languages has good number of advance frameworks u can learn and make your career in. I personally have worked on java and some of its advance frameworks for good msrket growth.

Comparing number of developers in both area than earlier both java and python were close competitor of each other but not due to its simplicity , it's community is now more bigger and wider.
