Yes, it's worse. You introduced twos bugs. First the space between the two
fragments was lost. Second the f on the second f-string was dropped. I see
these kinds of line-wrapping errors frequently. The bugs are CAUSED by the
line length rule.
Also, in the case of multi-line templates, there is no way to wrap them without
getting very far from WYSIWYG:
def run_diagnostics(location, system, test_engineer):
...
if (failures):
print(dedent(f'''\
There were {num_failures) anomalies detected in the {location}
{system} at {event_time ::%I:%M:%S}}.
These anomalies were classified as {level}. Further action is {''
if escalate else 'not'} recommended.
''')
else:
print(dedent(f'''\
A total of {num_test_cases} diagnostics were run in the {location}
{system} as of {event_time::%I:%M:%S}}.
No anomalies were detected and further action is not required.
Test signed by {test_engineer.title()}.
