List manipulation in Python :

List is one of the simplest data structures in Python.Its very important and Lists are enclosed in square brackets [ ]. each item is separated by a comma.Every List item assign unique index no. A list is mutable, meaning you can change its contents. Lists have many built-in control functions.

Methods of List objects are:

Creation:

L = ['yellow', 'red', 'blue', 'green', 'black']

print L :

['yellow', 'red', 'blue', 'green', 'black']

Accessing/Indexing :

L[0]  = 'yellow'

Slicing:

L[1:4]  = ['red', 'blue', 'green']

L[2:]   = ['blue', 'green', 'black']

L[:2]   =  ['yellow', 'red']

L[-1]   =  'black'

L[1:-1] = ['red', 'blue', 'green']

Lengthof items in list :

len(L)  =  5

Sorting the list :

sorted(L) = ['black', 'blue', 'green', 'red', 'yellow']

Append to end of list:

L.append("pink")
