This code snippet iterates over each element in the list, checks if it matches the target string "apple", and sets the found variable to True if a match is found, demonstrating a basic but effective way to check for the existence of an element in a Python list....
On each iteration, we check if the current value is contained in the original list. If the condition is met, we set theone_in_listvariable toTrueand exit the loop. Thebreakstatement breaks out of the innermost enclosingfororwhileloop. ...
