# Samples of simple python arithmetic.

''' A quick note:  In order to print integers and floats,
they have to follow a comma OR be formatted as a number type.
You can't do the following:

>>> print '3 + 5 = ' + simple_int

This attempts to "concatenate" a number and string together
(which you can't do) and results in an exception. To make it work,
you'd have to change "simple_int" to a string type.
>>> print '3 + 5 = ' + str(simple_int)

See PythonFormatOutput.py for formatting examples.'''
