#  This program demonstrates the use of a list,
#  which is a kind of dynamic array in Python.

#  A list can be defined by giving its values inside brackets [  ]
#  Lists can be concatenated by using the operator +

#  Lists can be indexed by giving an index expression inside brackets
#  after the list name. In this sense lists are like arrays of other
#  programming languages.
