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]).

Understanding Indexing and Slicing in Python
Meaning you can reference the elements in the sequence from right to left. ... The slice() function is called by Python internally when slicing notation is used. The my_list[0:8:2] is internally translated into my_list.__getitem__(slice(0,8,2)). You will learn more about __getitem__() in the next sections.

List slicing in Python
With Python's slicing syntax, the first item is the start index, and the second item is the stop index.The start index is inclusive, but the stop index is exclusive, meaning Python stops just before the stop index.. So we got the items at index 1 and index 2 because we stopped just before index 3.. Default slice start/stop values. The start and stop values are both optional when slicing.

Python Slicing Clearly Explained - Saurus.ai
Python users often mistakenly think that there is a different concept called “string slicing” in Python. However, string slicing is exactly the same as slicing for any other indexable and follows the same rules you’ve seen so far. Python strings are indexable on their individual characters and behave like lists of characters. Example:

Python List Slicing: How to Use It [With Simple Examples] - Codefather
When writing a Python program you might want to access multiple elements in a list. In this scenario, Python list slicing can be very useful. With Python’s list slicing notation you can select a subset of a list, for example, the beginning of a list up to a specific element or the end of a list starting from a given element.
