Characteristics of python list

The crucial characteristics of Python List are listed below-

1. Lists can contain any arbitrary objects

list = [ 10, 20, 12, 9 ]
print( list )
Output
[ 10, 20, 12, 9 ]

list = [ ‘Ajay’ , ‘Raju’, ‘Vipin’]
print( list )
Output
[ ‘Ajay’ , ‘Raju’, ‘Vipin’]

Or it can contain mixed values

list = [10, ‘Ajay’, 20 ]
print( list )
Output
[10, ‘Ajay’, 20 ]

The order in which we specify the list elements. It maintains the order of the list lifetime.

Example 1:-

   a = [5, 7, 1, 15]
   print(a)
Output
   [5, 7, 1, 15]

a =5, 7, 1, 15] [5, 7, 1, 15]

Example 2:-

list = [10, 20, 30, 40, 50 ]
if we want to get element 30 then we will write-
print( list [2] )
output
30

The indexing of a list is the same as an array starting from 0, 1 , 2 ….

we can easily access any element of the list from its index.

Example 1:-

list = [10, 20, 30, 40, 50 ]
if we want to get element 30 then we will write-
print( list [2] )
output
30

Example 2:-

list = [10, 20, 30, 40, 50 ]
if we want to get element 20 then
print( list[-4 ])
output
20

Once a list has been created, elements can be added, deleted, and shifted. Python provides a wide range of ways to modify a list.

Example :-

list = [10, 20, 30, 40, 50 ]
if we want to change the fourth element then
list[3] = 7
print(list)
Output
[10, 20, 30, 7, 50 ]

A list can contain sublists, which in turn can contain sublists themselves and so on to arbitrary depth.

a = [ 1, 2, [ 10, 20, 30, [100, 500 ], 40, 50 ], 3, 4, 5 ]
print( a )
Output
[ 1, 2, [ 10, 20, 30, [100, 500 ], 40, 50 ], 3, 4, 5 ]
