Conditional statement in a one line lambda function in python?
Use the exp1 if cond else exp2 syntax. rate = lambda T: 200*exp(-T) if T>200 else 400*exp(-T) Note you don’t use return in lambda expressions.
Ruby ternary operator without else
As a general rule: you pretty much never need the ternary operator in Ruby. The reason why you need it in C, is because in C if is a statement, so if you want to return a value you have to use the ternary operator, which is an expression. In Ruby, everything is an expression, … Read more
What is ?: in PHP 5.3? [duplicate]
?: is a form of the conditional operator which was previously available only as: expr ? val_if_true : val_if_false In 5.3 it’s possible to leave out the middle part, e.g. expr ?: val_if_false which is equivalent to: expr ? expr : val_if_false From the manual: Since PHP 5.3, it is possible to leave out the … Read more
Iif equivalent in C#
C# has the ? ternary operator, like other C-style languages. However, this is not perfectly equivalent to IIf(); there are two important differences. To explain the first difference, the false-part argument for this IIf() call causes a DivideByZeroException, even though the boolean argument is True. IIf(true, 1, 1/0) IIf() is just a function, and like … Read more
C# conditional AND (&&) OR (||) precedence
Change the first false by true. I know it seems stupid to have (true || true) but it proves your point. bool result = true || true && false; // –> true result = (true || true) && false; // –> false result = true || (true && false); // –> true

Dim Result = IF(expression,<true return>,<false return>) SEE ALSO: IIF becomes If, and a true ternary operator Is there a conditional ternary operator in VB.NET? Orcas introduces the IF operator – a new and improved IIF The Ternary Operator in VB.NET
Why doesn’t Java have compound assignment versions of the conditional-and and conditional-or operators? (&&=, ||=)
Reason The operators &&= and ||= are not available on Java because for most of the developers these operators are: error-prone useless Example for &&= If Java allowed &&= operator, then that code: bool isOk = true; //becomes false when at least a function returns false isOK &&= f1(); isOK &&= f2(); //we may expect … Read more
Ternary operator ?: vs if…else
It is not faster. There is one difference when you can initialize a constant variable depending on some expression: const int x = (a<b) ? b : a; You can’t do the same with if-else.
