LIST

List is an ordered sequence of items.
It is one of the most used data type in python and is very flexible.
All the items in list do not need to be of same type.
List is one of 4 built-in data types in Python used for collection of data, the other 3 are Tuple , set and Dictionary.
List is created using square brackets.

Example:1

nums=[12,34,56,78,89,12]
print(nums)

output: [12, 34, 56, 78, 89, 12]

Items in a list

Items in a list are changeable, ordered and allow duplicate values.
List items are indexed, starting from [0] index value.

Here the term ordered refers that, it means the items have a defined order, and this order cannot be changed.
If in case any new items are added to the list that will be placed at the end of the list.

Here the term changeable indicates that the values in a list can be removed, added or changed after the creation of list.

In a list it allows us to have the repeated values

Example2

>> lst=[12, 34, 45, 67, 89,12]

>>print(lst)

In list indexing is as in string i.e., left to right for reversal printing then indexing is done from right to left.
If you want to pick up the third value that is second indexed value then
