#  This is a simple calculator program that can
#  calculate the sum of the two integers that are
#  typed in from the keyboard.

#  The number sign (#) starts a comment line in Python.

#  All statements in Python 'main' program must begin in the
#  first column. Statements may not be indented unnecessarily since
#  indented statements form a nested program block.

#  You must use a backslash (\) to continue a statement on the
#  following program line.

#  Variables are not declared in Python programs. Instead, variables
#  are 'born' when they are assigned values.

#  Built-in runction input() reads a string from the keyboard.

#  Built-in function int() converts a string to an integer value.

#  Built-in function print() prints text to the terminal window.
#  The print() function prints a newline to the end unless the
#  parameter end = "" is specified.

#  See programs Distance.py and Formatting.py in pythonfiles2 for
#  information about the format specifiers (e.g. %d).

print( "\n Please, type in an integer:      ", end = "" )
first_given_integer  =  int( input() )

print( "\n Please, type in another integer: ", end = "" )
second_given_integer  =  int( input() )

sum_of_two_integers  =  first_given_integer  +  \
                        second_given_integer

print( "\n The sum of %d and %d is %d. \n"  %  ( first_given_integer,
      second_given_integer, sum_of_two_integers ) )
