This is a Mathics3 Python Module showing the classic "Hello, World!" The purpose is to demonstrate how to write a Mathics3 Python Module which extends Mathics3 by adding a function, but written in Python.

You can also use this as a template to clone if you want to create your own Mathics3 Module.

To install in development mode (run code from the source tree):

$ make develop

After installing inside Mathics3, you can load this using the LoadModule[] function.

Then the function `Hello[] is available:

$ mathicsscript
In[1]:= LoadModule["pymathics.hello"]
Out[1]= pymathics.hello

In[2]:= Hello["World"]
Out[2]:= Hello, World!

You can test with py.test:

$ py.test test

or simply:

$ make check
