Python has some list methods which are built-in that you can use to perform frequently occurring tasks (related to list) with ease. For example, if you would like to add element to a list, you can make use of a
aList=[123,'xyz','zara','abc']aList.insert(2,['2','3','4'])print("Final List : ",aList) Once we execute the program above, the final list is displayed with the list object insert into the existing list as a single object. It is shown below. ...
