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:

$ pytest test 

or simply:

$ make check
