By using square brackets, like in the option identified as the correct answer, you directly declare an empty list. This is a syntactically concise approach, and it’s widely recognized among Python programmers. It’s also very efficient in terms of performance.

The list() constructor is another valid way to create an empty list. When you call list() with no arguments, it returns an empty list as well. Although this method is a bit more verbose, it serves the same purpose effectively. However, it lacks the simplicity and clarity that using square brackets provides, which is why many developers prefer the first method.

The first option uses curly braces, which actually creates an empty dictionary, not a list. This is a common mistake, as both lists and dictionaries share some similarities but are used for different purposes in Python.

The last option mentions null, which is not a keyword in Python. The equivalent in Python is None, but even that wouldn't create a list; it simply assigns the value of None to the variable.

Therefore, the ideal way to declare an empty
