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]).

Python slice() Function - W3Schools
The slice() function returns a slice object. A slice object is used to specify how to slice a sequence. You can specify where to start the slicing, and where to end. You can also specify the step, which allows you to e.g. slice only every other item.

slice - How slicing in Python works - Stack Overflow
In Python 2.7. Slicing in Python [a:b:c] len = length of string, tuple or list c -- default is +1. The sign of c indicates forward or backward, absolute value of c indicates steps. Default is forward with step size 1. Positive means forward, negative means backward. a -- When c is positive or blank, default is 0. When c is negative, default is -1.

Python List Slicing - Learn By Example
Slicing with Negative Indices. When slicing lists in Python, you can use negative indices as well. This allows you to reference elements from the end of the list. For example, the index -1 represents the last element, -2 represents the second-to-last element, and so on. Consider the same list of letters.

Python Slicing: 9 Useful Methods for Everyday Coding - Analytics Vidhya
Slicing Methods in Python. Basically, Python offers 2 different ways of slicing. One is [start: end: step] and the other is the .slice(start, stop, step) function. In this section, first we will go through the syntax of these slicing operations, after this we will explore the major types of slicing that we can perform in Python.

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.

How to Slice Lists/Arrays and Tuples in Python
On the other hand, entering the stop parameter is mandatory since it indicates to Python the index to which slicing is supposed to take place. By default, Python will stop the slicing at the value “stop - 1.” In other words, if the stop value is 5 when using the slice function, Python will only return values till the index value is 4.

Python Slice: Useful Methods for Everyday Coding - DataCamp
Basic Methods for Slicing in Python. As I said, slicing is a core feature in Python, allowing developers to extract portions of sequences like lists, strings, and tuples. Python offers two primary ways to slice sequences without importing anything: the slicing : syntax and the slice() function.
