Conventional if statements in Python do use your preferred form of `if COND then TRUE-CASE else FALSE-CASE`.
What you are talking about is a different kind of expression, similar to a ternary operator. It is not the same as if...else

The reason it's not the same as if...else is that it's freaking backwards :D

You said:

And this is wrong -- this is not how Python if statements work.

Huh? Didn't you yourself say I was not talking about if statements:
> What you are talking about is a different kind of expression, similar to a ternary operator. It is not the same as if...else
In any case, I'm talking about the case that goes `TRUE-CASE if COND else FALSE-CASE`, as can be deduced from my typing `TRUE-CASE if COND else FALSE-CASE`.

It's a very opinionated statement on my part. `if COND then TRUE-CASE else FALSE-CASE` is the correct form to use, in my opinion. Python uses `TRUE-CASE if COND else FALSE-CASE`.
