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.

Ordered

• 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.

Changeable

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

Allow Duplicates

In a list  it allows us to  have the  repeated values

Example2

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

>>print(lst)

Indexing in list

• 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
