Hello Kumar,

Excellent, welcome to Ignite community!

If you’re thinking of python library implementation then I suggest to build 
some skills resolving C++ related tasks:
https://issues.apache.org/jira/browse/IGNITE-4597 


https://issues.apache.org/jira/browse/IGNITE-4617?jql=project%20%3D%20IGNITE%20AND%20resolution%20%3D%20Unresolved%20AND%20component%20%3D%20platforms%20AND%20(text%20~%20%22C%2B%2B%22%20OR%20text%20~%20CPP)%20ORDER%20BY%20updatedDate%20DESC
 


BTW, this is information that might be useful to you as well.

Get familiar with Ignite development process described here:
https://cwiki.apache.org/confluence/display/IGNITE/Development+Process

Instructions on how to contribute can be found here:
https://cwiki.apache.org/confluence/display/IGNITE/How+to+Contribute

Project setup in Intellij IDEA:
https://cwiki.apache.org/confluence/display/IGNITE/Project+Setup

Once you got familiar and were able to run a few examples, you should pick
a Jira ticket you would like to start on. Send an email to the dev list sharing 
your JIRA id, so we can add you as a contributor in Jira.
