#  The corresponding Java/C++/C# programs use special
#  keyboard input mechanisms. This program, however, uses
#  the standard raw_input() function. Indexing is
#  used to access the individual characters of the
#  given sentence.

#  The print statement automatically prints a space
#  character after each printing operation.

#  Python programs have the same kind of block structure
#  as programs written with other programming languages.
#  No braces {  }  are needed to specify where a block
#  starts or were it ends. Instead, indentation of program
#  statements are used to identify program blocks.
#  Statements beginning in the same column belong to the
#  same program block.
