What if you have a ternary operator that’s very long?<\/p>\n

var = 'I want to learn Python' if 42**2<166 else 'I want to learn Go programming'\nprint(var)\n# I want to learn Go programming\n<\/pre>\n
Problem<\/strong>: How to write the ternary operator in multiple lines?<\/p>\n
Short Recap: Ternary Operator <\/h2>\n
Ternary Operator<\/strong><\/a>: The most basic ternary operator x if c else y<\/code> consists of three operands x<\/code>, c<\/code>, and y<\/code>. It is an expression with a return value. The ternary operator returns x<\/code> if the Boolean expression c<\/code> evaluates to True<\/code>. Otherwise, if the expression c<\/code> evaluates to False<\/code>, the ternary operator returns the alternative y<\/code>.<\/p>\n
Syntax<\/strong>: The three operands are written as x if c else y<\/code> which reads as “return x<\/code> if c<\/code> else return y<\/code>“. Let’s write this more intuitively as:<\/p>\n
<OnTrue> if <Condition> else <OnFalse><\/pre>\n
