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?

return ('Yes' if a == b else 'No')

Yes, Python has ternary operator-like syntax:
return ('Yes' if a==b else 'No')

Note that this requires a recent version of Python.

Cheers,

And for less clutter you can even leave the parenthesis:

return 'Yes' if a == b else 'No'

Who let the dogs in? That's awful syntax.
