Call Python functions from javascripr/browser

I have a huge python implementation which I donot want to rewrite in JS . This python will keep changing as my business changes. Hence no rewrite to js.

this python takes some inputs and sends back results in a tuple format. So, what are the ways to execute this python in browser and call the methods defined in python?

example: C# has IronPython to call python from C#.

Any help is greatly appreciated.

Here is one link i found but which is little helpful [https://ift.tt/3mupaqn]
