Multiple elements can be kept in a single variable by using lists. One of Python’s four built-in data types for storing data collections is the list; the other three are the tuple, set, and dictionary, each of which has a unique purpose.  

In Python, an empty list has no items or elements. It is created using square brackets with nothing inside, like this: []  

  • []: The [] operator is used for various purposes, including indexing, slicing, and list comprehension. When used for indexing, the [] operator allows you to access a specific element of a list, tuple, or other iterable objects by its index position.  

Returning an empty list can indicate that a function or method has been completed without finding valid results or items that match certain criteria. It can also be used as a default value for a function or method that may return a list of items in some cases but not others. Additionally, an empty list can be used as a placeholder for a list filled with items later.
