May 6, 2023 · In Python, by using a slice (e.g., [2:5:2]), you can extract subsequences from sequence objects, such as lists, strings, tuples, etc. In a slice, the start and stop positions for the subsequence are denoted as [start:stop]. The extracted range is start <= x < stop, including the item at start but excluding the item at stop.

List slicing in Python allows extracting specific parts of a list by specifying a start index, an end index, and an optional step. Slicing helps access a subset of elements without modifying the original list. List slicing follows the syntax: start: The index where slicing begins (inclusive). end: The index where slicing stops (exclusive).
