The only issue in using Coconut without any prior Python experience is that there's no Coconut-specific tutorial for the basic syntax stuff that Coconut inherits from Python. That being said, if you just go through any Python tutorial, using Coconut instead of Python, you should do fine! So, I'd recommend going through the Coconut tutorial
until you get to the point where you have everything installed and have written your "hello world" program, then switch to a Python tutorial to learn the basics, then after you can switch back to the Coconut tutorial. See "I don’t know Python very well, should I still learn Coconut?
" for the FAQ entry on this question.
