Syntax 3: list_object.index(value, start=startingNumber, stop=endingNumber) Syntax 2: list_object.index(value, start=startingNumber) Function will throw error if value is not present in the list. By default it will return index of first occurence of value.
Syntax: list_object.insert(index_position, value) Insert At in List: insert() function can be used to insert item at a specified index.Example 3: Statement will iterate thru input string 'DBMS' and add each character in the input string as individual item at the end of the list.Example 2: Statement will iterate thru input object list "" and add each item in input list as individual item at the end of the main list.Output: TypeError: 'int' object is not iterable Example 1: Statement will fail as integer values are not iterable.Function will iterate through all the elements in the input object and add them as individual item in the existing list. Extend List: extend() function requires iterable object(such as string, list) as input otherwise it will throw error.Visit this page to understand difference between extend and append functions Example 2: Statement will append input object "" as single item at the end of the list.Example 1: Statement will add value 'C' at the end of the list.Append to List: append() function appends the input value at the end of the list.Example 2: This will return Zero(0) as there is no item present in the list.Example 1: Statement will return 5 as there are 5 items present in the list.
Length of List: len() function can be used to get the number of items present in the input list.➠ Most of the list functions available in Python are listed below, click on the required function to get more detail and sample examples. Please visit this page to understand List in detail. This page will specifically cover available built-in Python functions which helps in performing variety of operations(such as adding, modifying & deleting items) on list objects.
