Question

Describe the following list methods: a) index b) insert c) sort d) reverse

Answer 1

List methods include index (finds element's index), insert (adds element at index), sort (arranges elements in order), and reverse (reverses the list order).

Step-by-step explanation:

The methods index, insert, sort, and reverse are common list methods in many programming languages, such as Python. Here is a brief description of each:

• index: This method returns the first index at which a given element appears in the list. If the element is not found, it typically raises an error.
• insert: This method allows you to insert a new element into the list at a specified index. The element at that index and all subsequent elements are shifted to the right.
• sort: This method sorts the items in the list in place, meaning the original list is modified. You can sort the list in ascending or descending order, and custom compare functions can often be provided to control how the sorting is done.
• reverse: As the name suggests, this method reverses the order of elements in the list, modifying the original list.
