#  The 'print' command in Python is a statement, i.e.,
#  'print' is a reserved keyword.

#  The print statement prints a newline after each 
#  printing operation unless there is a comma at the end
#  of the print statement. The print statement adds a
#  space character after each printed item.

#  The for loops in Python programs resemble the 'foreach'
#  loops of Java and C# langauges. In the following loop
#  range( 21 ) specifies that number_to_print will have
#  all the values from 0 to 20.

print  "\nNumbers from 0 to 20 are the following:\n"

for number_to_print in range( 21 ) :

   print "%d"  %  number_to_print,
