👉 In programming, a characterless function is a function that does not take any input or return anything. This means that the function has no effect on the execution of the program and can be used in different contexts without changing its behavior. For example: ```python def greet(name): print(f"Hello, {name}!") ``` This would output "Hello, John!" when the function is called with the name "John". Characterless functions are often used to simplify code or reduce complexity
