    Program 11: To create a list

                         Program11.py
                      File  Edit  Format   Run   Options   Window     Help

                      a= [10, 20, 30, 40, 50]                                      Output
                      print (a[2])                                              30

                     Let us study about some of the ways through which we can create different types of lists.

                     Empty List
                     An empty list in Python is created using square brackets [ ]. You can also create a empty list by
                     using the list() function.
                     Program 12: To create an empty list

                         Program12.py
                      File  Edit  Format   Run   Options   Window     Help

                      picnic=[]
                      print (picnic)                                               Output
                      exam= list()                                              []
                      print (exam)                                              []

                     Mixed Data Type List
                     Mixed data type list can be created to place different data types such as integers, strings,
                     double, etc.
                     Program 13: To create a mixed data type list

                         Program13.py
                      File  Edit  Format   Run   Options   Window     Help
                      a=['Ravi', 'Bhatt', 12, 13, 14]                              Output
                      print (a)                                                 ['Ravi', 'Bhatt', 12, 13, 14]

                     Nested List

                     A list can contain other lists as elements, which is known as a nested list.

                     Program 14: To create a nested list
                         Program14.py

                      File  Edit  Format   Run   Options   Window     Help
                                                                                   Output
                      a=['Lakshaya', 'Sameer', 10, 20, [1,2,3],7]
                                                                                ['Lakshaya', 'Sameer', 10, 20,
                      print (a)
                                                                                [1, 2, 3], 7]

                                                                                       Functions, String and List in Python  97
