It (imao) really depends. If I see
if a == 'foo':
do nothing
else:
do what I want
I always expect a equalling foo to be the primary result being tested
for, as it comes first. When it comes time to bug hunt, it takes a
mental readjustment to realise that I don't want a to be 'foo', and it
involves reading do nothing.
Hence,
if not a == "foo" :
do what I want
else:
do nothing
is much more obvious to me, I consider 'elses' to be secondary, and I
(personally speaking) always look at the first conditional, and expect
it to be the primary action, if you get my drift.

'There is only one basic human right, and that is to do as you damn well please.
And with it comes the only basic human duty, to take the consequences.
