​Just an FYI, ​
doctest has an option NORMALIZE_WHITESPACE
https://docs.python.org/3.5/library/doctest.html#doctest.NORMALIZE_WHITESPACE
​"
When specified, all sequences of whitespace (blanks and newlines) are
treated as equal. Any sequence of whitespace within the expected output
will match any sequence of whitespace within the actual output. By default,
whitespace must match exactly. NORMALIZE_WHITESPACE
<https://docs.python.org/3.5/library/doctest.html#doctest.NORMALIZE_WHITESPACE>
is
especially useful when a line of expected output is very long, and you want
to wrap it across multiple lines in your source.
