Go with Python.

Python and C/Java share a lot syntax-wise, but python is higher-level, more beginner friendly language - it's got REPL, big community, lots of intro books and libraries.

And even if you decide not to start with Python, avoid C. As a beginner, you don't want to deal with manual memory management on top of everything else that you have to learn to be a coder.

Most importantly, have fun! :)
