The NLG library for Finnish
Syntax maker is a full-blown Python library for generating syntactic Finnish sentences. It’s available through pip, if you got interested. See syntax maker on PyPi.
It can turn lemmatized words into full sentences in a heart beat. Just throw words such as rantaleijona, uneksia, erittäin, korkea and aalto, and like magic, you will get rantaleijonat uneksivat erittäin korkeista aalloista. Want to learn how? Take a look at the syntax maker wiki for a tutorial.
So what are you waiting for? just run pip install syntaxmaker and start producing syntactically correct Finnish today!
