There are many other functions available in Python that are given here with examples to perform this task. lists = [base]. In Python, we have several ways to perform the indexing in list, but sometimes, we have more than just an element to index, the real problem starts when we have a sublist and its element has to be indexed. The next function checks for the elements and enumerate functions separates the nested list elements. Lists are created using square brackets: Previous: Write a Python program to check whether a list contains a sublist. In this approach we convert the lists into set and use the subset functions to validate if the small list is part of the bigger list or not. list[n:m] → return a sublist from index n to m. list[:m] → from beginning to m. list[n:] → from n to the end, including the end element. It is also possible to delete items using del In Python, we have several ways to perform the indexing in list, but sometimes, we have more than just an element to index, the real problem starts when we have a sublist and its element has to be indexed.
