Hi, how can I write the popular C/JAVA syntax in Python?
Java example:
return (a==b) ? 'Yes' : 'No'
My first idea is:
return ('No','Yes')[bool(a==b)]
Is there a more elegant/common python expression for this?
Yes, Python has ternary operator-like syntax:
return ('Yes' if a==b else 'No')
Note that this requires a recent version of Python.
Who let the dogs in? That's awful syntax.
Yes, that's deliberately awful syntax. Guido designed it that way to
ensure that people didn't aver-use it, thereby reducing the readability
of Python applications.
Is that for real??? It's the QWERTY rationale all over again. Swell.
The rationale I remember is that it's intended primarily where the
condition is usually true, with the false only being once in a while.

Second, sticking the test between the two alternatives goes against
a vast tradition in programming languages. This tradition inevitably
fosters habits and expectations when reading code, so going against
it automatically makes code less readable to all who were educated
in that tradition.
So you're saying that new languages can't change anything already well
established? So much for break-through innovations.
And what about the programmers? It is good to learn to think in
different ways.
At any rate, I far prefer it over C's syntax.
