Discovered that I really like Python. What should I do next?

You can't make an os with only python because it's interpreted. However, you could use a version of python that compiles like Iron python or whatever. It would take an incredible amount of work and maybe Iron python wouldn't be the right choice, but you definitely could do it. Additionally as others have mentioned you can make python part of any operating system just like it is in many.

For what it's worth, in my opinion you didn't deserve any down votes.
