The correct way to create an empty list in Python is by using square brackets, as indicated in the chosen response. When you write empty_list = [], you are explicitly defining a list data structure that contains no elements. This syntax is clean and clear, adhering to Python’s design principles, which favor readability and simplicity.

In contrast, the other choices do not create an empty list. For example, using curly braces like in the first choice would create an empty dictionary instead of a list. The third option assigns None to the variable, which is a special value in Python representing the absence of a value or a null value, not a list. The final option, consisting of empty quotes, creates an empty string, which is a fundamentally different data type compared to a list. Hence, only using square brackets is the appropriate way to initialize an empty list.
