how to return False in ternary condition

[deanhystad]

return statement can only be used in a function, not elsewhere

This may or may not be a problem here. We have no context provided for the code in question. But this is invalid Python if it is in a function or not. "return" is not an expression. A ternary expression is "expression condition expression". In

answer = 'odd' if x % 2 else 'even'

'even' and 'odd' are expressions and 'if x % 2 else' is the condition.

An expression is something that evaluates to a value. A string is an expression. An equation is an expression. A function call is an expression. A "return", ironically, is not an expression because it does not evaluate to a value.
