If there is anyone in class whose first name is You can use this to your advantage – and understanding this will help you understand other people’s code better, andīe able to walk through code more confidently.Ĭonsider a situation where you want to write a function to find out, from a class attendance list, whether anyone’sįirst name is longer than five letters, called longer_than_five. The following example is a situation where Understand for writing complex programs, and it can also be very useful. The fact that a return statement immediately ends execution of the code block inside a function is important to Variables for the square function are in separate boxes. You can see this very clearly in codelens, where the global variables and the local It doesn’t matter what the value was named in the caller (the place where the function was invoked). It is as if x = toSquare is executed when square isĬalled. The name of the variable we pass as an argument - toSquare - has nothing toĭo with the name of the formal parameter - x. These temporary variables are referred to as local variables. On the other hand, using temporary variables like y in the programĪbove makes debugging easier. ![]() Try modifying the square functionĪbove to see that this works just the same. Because the return statement can contain any Python expression we could haveĪvoided creating the temporary variable y and simply used return x*x. ![]() Its result is returned to the caller as the The return statement is followed by an expression which is evaluated.
