Python ternary operation (? ' ' : ' ' )

 Python does not have ternary operation (condtion ) ? TRUE_clause : FALSE_clause

but can use a typo instead

You can index into a tuple:

(falseValue, trueValue)[test]

test needs to return True or False.

It might be safer to always implement it as:

(falseValue, trueValue)[test == True]

or you can use the built-in bool() to assure a Boolean value:

(falseValue, trueValue)[bool(<expression>)]
