Python List Slicing - GeeksforGeeks
Out-of-bound slicing. In Python, list slicing allows out-of-bound indexing without raising errors.If we specify indices beyond the list length then it will simply return the available items. Example: The slice a[7:15] starts at index 7 and attempts to reach index 15, but since the list ends at index 8, so it will return only the available elements (i.e. [8,9]).

Using square brackets: my_list = [1, 2, 3] Using the list() constructor: my_list = list((1, 2, 3)) Using list comprehensions: my_list = [x for x in range(5)] 3. Accessing Elements To access elements in a list, you use indexing. Python uses a zero-based index system, meaning the first element has an index of 0. For example:

A list may contain mixed type of items, this is possible because a list mainly stores references at contiguous locations and actual items maybe stored at different locations.
