👉 Validates is a technical concept in computer science that refers to a function or method that checks the validity of an input parameter before it is used in a program. It involves ensuring that the input data meets certain criteria, such as its length, type, or format. For example, consider a user's input: ``` user_input = "Hello, world!" print(validate_user_input(user_input)) ``` This would output `True`, which means that the string is valid according to the Python language
