You know those puzzles that present you with some numbers, and then ask you what the next number in the sequence should be? Like 1, 4, 7, ...

Well, this little tool can create a variety of such puzzle sequences, with different rules of complexity including multi-step operations.

To be clear, I am not an experienced Python Programmer. It's written in Python because I happened to be maintaining some Python code at the time. So some of this may look sane, other bits may look atrocious :)

In any case, as long as you find it useful, that's good. Improvements (pull requests!) welcome. Also ports to other languages, such as Go. Enjoy!
