def _is_unorderable_exception(e):
if PY36:<EOL><INDENT>return "<STR_LIT>" in str(e)<EOL><DEDENT>return '<STR_LIT>' in str(e)<EOL>
Check if the exception raised is an unorderable exception.

The error message differs for 3 <= PY <= 3.5 and PY >= 3.6, so
we need to condition based on Python version.

Parameters
----------
e : Exception or sub-class
    The exception object to check.

Returns
-------
boolean
    Whether or not the exception raised is an unorderable exception.
