There will be a GCI 2015, stay tuned to this list and the Google Open Source blog in mid October for more details and the official announcement with dates, information, etc.
Google Code-in is designed for beginners so you do not have to be an experienced coder to participate. There will be tasks in a variety of coding languages (Python, C++, etc.) and there will also be many tasks that don't require any coding at all.
You will be able to go through the list of tasks and look for something that you think is interesting and that you think you can do. You are encouraged to ask questions from the mentors if you get stuck while working on a task.
Visit
g.co/codein for more information on Google Code-in.
Best,
