Is there a way to implement python code into a website?

So hello people,

Basically... I have a website and some python code that I have just written out. And I was wondering, if possible I could implement that python code into my website.

So, like my python code is a password generator. Is there any way to put that into a js onclick function or just in a website. Or, will I have to write out the code but in js instead?

I am not using node.js
