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]).

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.
