## Words & not words

Data-driven documents go beyond words to include data, code, & visuals fill voids in language.

### Computational Documents are multi-lingual

  • Code > Narrative

  • Narrative > Code

Which is role the of "data scientist", and "software engineer"?

my_function_that_changes_the_world_cause_I_said_so then I’ll key programming

Code > Narrative

Informal names are adopted for literacy and narrative in "docstrings" are secondary to the code.

    def my_function_that_changes_the_world_cause_I_said_so(): 
        """>>> assert 42, 'This function does not change the world'"""

def my_function_that_changes_the_world_cause_I_said_so(): 
    """>>> assert 42, 'This function does not change the world'"""

Narrative Over Code

my function that changes_the_world cause I said so` then I’ll key programming

def function(): """>>> assert 42"""
def changes_the_world(): """>>> assert True"""

Literate documents include code & multimedia in formal language to connect features of the human and machine language.

### Doctesting and docstrings

    import doctest

Tests provide trust to an `object`.  Place `doctest`s in your function to run tests interactively.

    doctest.testmod()

TestResults(failed=0, attempted=3)

Notebooks simulate a document.

They are a flexible form to project different forms of multi hypermedia documents.
