What do you call a list that contains another list which itself contains other lists?

• A. 3D array
• B. Multi-dimensional array
• C. Cube
• D. Nested list

Answer: (C)

A list that contains another list, which in turn can also contain other lists, is referred to as a nested list. This structure allows for the organization of complex data in a hierarchical format, where lists can hold other lists as their elements. The key feature of a nested list is that it can represent multi-level data structures, enabling the representation of matrices, tables, or any data that naturally fits into a multi-dimensional space. For instance, a nested list can effectively represent a 2D grid where each element is itself a list of values. This versatility in handling lists within lists is why the term "nested list" is used. While the other terms such as "multi-dimensional array" and "3D array" describe similar concepts in the context of arrays, they are more specific to array data structures often used in programming languages like C or Java, which implement fixed-size dimensions. Therefore, "nested list" is the appropriate term in Python, particularly in contexts where lists are structures that can dynamically grow and accommodate arbitrary dimensions.
