AFAIK, we do not have "postfix conditionals" in Python, i.e. a
condition appended to a statement, which determines whether the

The above piece of code is equivalent to this in Python:
py> for i in [False]:
... if not i
... break
I believe that the first example is superior to the second example
when the two is compared for readability and intuitiveness.
In my past life as a newcomer to Perl, I thought this too. Postfix
conditionals read more like English, so they would be easier to take
in and understand. As I wrote more code, I discovered that this
didn't seem to be the case; except in very simple cases, I had to
mentally transpose the conditional back to the start of the statement
to properly comprehend what was going on and what the results would be
for my sample data.
It looks like a good idea, but I don't think it works that well in
practice.
Thanks for the input! I'd be quite interested in examples which required
you to "mentally transpose the conditional back to the start of the
statement", by the way.
