Examples of mixed code and session blocks

This file (project.md) has some example code and session blocks including a Python doctest directive example.

An example with a blank line in the output

Note no <BLANKLINE> directive in the output block of a Python code block output block pair.

def greeting(name: str) -> str:
    return "Hello" + "\n\n" + name

print(greeting("World!"))

Here is the output it produces.

Hello

World!

A second FCB that calls the function greeting() defined in the first FCB.

text = greeting("Planet!")
text = text.replace("\n\n", " ")
assert text == "Hello Planet!"  # this assert is in the Markdown example.

Interactive Python session requires <BLANKLINE> in the expected output

Blank lines in the expected output must be replaced with <BLANKLINE>. To see un-rendered Markdown navigate to tests/md/project.md on GitHub and press the Code button.

>>> print("Hello\n\nWorld!")
Hello
<BLANKLINE>
World!

Interactive Python session with doctest directive

Here is an interactive Python session showing an expected exception and use of the doctest directive IGNORE_EXCEPTION_DETAIL. To see the doctest directive navigate to main branch project.md unrendered.

>>> int("def")    #doctest:+IGNORE_EXCEPTION_DETAIL
Traceback (most recent call last):
    ...
ValueError:

Session with py as the fenced code block info_string

>>> coffee = 5
>>> coding = 5
>>> enjoyment = 10
>>> print(coffee + coding)
10
>>> coffee + coding == enjoyment
True
