How can you get the length of a list named `my_list`?

The function that returns the length of a list in Python is len(my_list). This built-in function takes a single argument, which is the list, and it returns the number of elements contained in that list.

Using len(my_list) adheres to Python's syntax and conventions. It is efficient and concise, making it the standard way to retrieve the size of a list or other iterable objects in Python.

Other methods, such as attempting to use length(my_list), my_list.length(), or size(my_list), do not actually exist in Python. There is no built-in function called length, and lists do not have a method called .length(). Similarly, there isn't a function called size() in the core Python language for finding the length of a list. This reinforces why len(my_list) is the correct approach.
