👉 In programming, a "liber" is a type of variable that can be assigned to multiple values at once. This means that if you assign two different values to a single `Lib` object, it will have two copies of the same value in its memory location. For example: ```python l = Lib() l.name = 'Alice' print(l.name) # Output: Alice l.name = 'Bob' print(l.name) # Output: Bob ```
