Mutability refers to the ability of an object or a data structure to be changed or modified after it has been created. In programming, this concept is important for understanding how different types of data behave. 1. **Mutable Objects**: These are objects whose state or content can be changed without creating a new object. For example, in Python, lists and dictionaries are mutable data types.
