How do you access the first element of a list named 'my_list'?

Explanation:
To access the first element of a list named 'my_list,' you use the syntax my_list[0]. In Python, lists are indexed starting from zero, meaning the first item in the list can be accessed with the index of 0. Using square brackets with the index allows you to directly retrieve or manipulate the element at that position. For example, if my_list is defined as `my_list = [10, 20, 30]`, then `my_list[0]` would return 10, which is the first element. The other methods mentioned, like using parentheses or methods like first() and get(), do not apply to lists in Python. Lists do not have a built-in method called `first()` to retrieve the first element, nor is the `get()` method used with lists as it is with dictionaries. Additionally, parentheses are used for function calls, and thus my_list(1) is not a valid way to access an element in a list.
