The alternative to posting too much is to reduce your code to the
minimum needed to exhibit the behavior you want to change. Doing so may
reveal to you the solution. It will certainly make it easier for anyone
else to help you and will make any answer more useful to other readers.
Quentin privately sent me 12 lines (which should have been posted here
instead), which can be reduced to the following 4 that exhibit his bug.
if a == b:
print('correct')
if a != b:
print('incorrect')
The bug is a != b will never be true when a == b and will not be tested
when a != b. The fix is to use else.
if a == b:
print('correct')
else:
print('incorrect')
This should not be reduced to a conditional expression since different
code follows the print statements in the actual example.
