Call Functions from an External Language

ExternalFunction makes it easy to make functions from other languages, like Python, callable from the Wolfram Language. It is great for making functions from useful libraries available or as an interface to newly defined functions.

Start a new session.

Define a function in the session.

Create an ExternalFunction from this Python function.
