Like it can store integer value, float value, string value etc, in a single list. - A list of lists can also be created which means a list can also store different lists in it as well. #2 - Several operations can also be performed using it and it has many in-built functions and methods to use. - nums. shows all the functions that are available with the list. - Ctrl + Space can also be used to show the methods. - append method is used to add a new value to the end of a list. - clear will clear the entire list. - insert method can add a value in between the list at the specified index. - A particular element can also be deleted through the remove method. - pop method will also remove the element through the index value and return that deleted element as well. - If you don't specify the index value in the pop method, it will delete and return the last element from the list. - del is a command through which you can delete a sub-list or multiple values from a list. del list name[start:end] - extend method is used to add multiple values or a sub-list in a list. - sort method is used to get listed in the sorted order. nums.sort() #3 - min() function is used to get the minimum value present in a list. - max() function is used to get the maximum value of a list. - sum() function returns the sum of all of the values present inside the list.
