![]() Visit this page to understand difference between remove and pop functions Example 2: Statement will remove first occurence of value 'b' from the list.Solution: Check if value is present before running remove function Output: ValueError: list.remove(x): x not in list Example 1: Statement will fail as value 'd' is not present in the list.Function will throw error if value is not present in the list. Remove object from List: remove() function can be used to remove first occurence of value in the list.Example 3: There is no occurence of value 5.Example 2: There are two occurence of value 6.Example 1: There is only one occurence of value 3.Syntax: list_unt(value_to_check_occurence) Count Occurences: count() function counts the occurence of value passed.It will return 9 as it is first occurence of value 'b' is in between 8th index and 10th index. Example 5: This statement will only check the availability of 'b' in between 8th index and 10th index.It will result in error as there is no 'b' value in between 4th index and 6th index. Example 4: This statement will only check the availability of 'b' in between 4th index and 6th index. ![]() Example 3: Statement will return 7 as the first occurence of value 'b' is starting from 4th item and is at index 7.Example 2: Statement will return 1 as the first occurence of value for 'b' is at index 1.Ī_list =.Solution: Check if value is present before running index function Example 1: Statement will fail as 'c' character value is not present in the list.Syntax 3: list_object.index(value, start=startingNumber, stop=endingNumber) Syntax 2: list_object.index(value, start=startingNumber) By default it will return index of first occurence of value. Index in List: index() function can be used to find position of item(value) in a list.Example 2: Item 'Y' got inserted at 2nd last position just before the last element.Example 1: Index of value 'f' in list is 2, therefore item 'X' got inserted at 2nd index before value 'f'.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.
