It breaks the loop execution and makes the function return immediately. To better understand this behavior, you can write a function that emulates any(). This built-in function takes an iterable and returns True if at least one of its items is truthy....
Returning One Value Take another look at our function’s code, which currently accepts any value as an argument, searches the supplied value for vowels, and then displays the found vowels on screen: Changing this function to return eitherTrueorFalse, based on whether any vowels were found, is...
