Something I forgot to add. This idea of side-effects with the conditionals is
actually the whole point of the Python built-in functinos any() and all().
any() will evaluate a generator expression and stops when one of them
evaluates to True, and all() works the same, but stops when a False is

Yes.
I don't know how python actually does it but in a general
sense there is not much if any diffe

I opened the wikipedia article for the english word, but didn't start

Hello,
Suppose we want some block of code to be executed when both '*a'* and
'*b'*are equal to say 5. Then we can write like :
*if a == 5 and b == 5:*
*# do something*
But a few days ago, I just involuntarily wrote a similar condition check as
:
*if a == b and b == 5:*
*# do something *
