I am new to java but i know python a little. I do not know whether python and java are inter related or not. If yes then how can I start learning both languages by comparing their features. And where are the good place in web(tutorial) from where I can start learning both.
This is the best python book i have read (both physical and e-book) http://diveintopython3.org/ or http://diveintopython.org/ if you are looking to learn python 2.4.
As I recall this book regularly mentions which feature are common between python and Java, and how they are different between java and php
To be honest I don't think its that big of an issue to learn two languages at the same time, you might get confused every once in a while about what was in what language but that has never stopped me ;)
Your question is similar to asking if it's possible to study English and French at the same time. Yes, it's possible. Yes, it's a good idea.
Definitely! And if I were you, I would start using jython (http://jython.org/), which is python 2.5 implemented on top of the jvm. You can learn python, and start calling java api from the jython code. Here's a link to their faq: http://wiki.python.org/jython/JythonFaq/EmbeddingJython
