Interesting, in the historical section we see:
The original version of this PEP proposed the following syntax:
<expression1> if <condition> else <expression2>
The out-of-order arrangement was found to be too uncomfortable
for many of participants in the discussion; especially when
<expression1> is long, it's easy to miss the conditional while
skimming.
But apparently those objections were either unknown or disregarded when
the syntax was later adopted.
