extend( ) Adds one entire list into another list.
Example: L1.extend( L2 ) Result: L1 = [ 1, 2, 3, 10, 20, 30 ]
copy( ) Returns the copy of list
Example: List1 = L1.copy( ) Result: List1 = [ 1, 2, 3 ]
count( ) Returns the count of elements in list
Example: L3.count( 12 ) Result: 3
index( ) Returns the index position of particular value in the list
Example: L2.index( 30 ) Result: 2
insert( ) Adds an item at a particular position in the list
Example: L1.insert( 2, “Python” ) Result: L1 = [ 1, 2, “Python”, 3 ]
pop( ) Removes an item at the end of the list
Example: L1.pop( ) Result: L1 = [ 1, 2 ]
remove( ) Removes an item at a particular position of the list
Example: L2.remove( 20 ) Result: L2 = [ 10, 30 ]
reverse( ) Reverse the items in list
Example: L3.reverse( ) Result: L3 = [ 12, 28, 12, 25, 12, 19 ]
sort( ) Sorts the items in ascending order Example: L3.sort( )
Result: L3 = [ 12, 12, 12, 19, 25, 28 ]
