Welcome to Python tutor.

Normally, the print statement accepts a list of items, separated by
commas.  Each item is implicitly converted to a string, and the results
are sent to standard out, with a space between each item.

So the most straightforward way to print z would be something like:

    print 'Addition of above two numbers are:',  z

Now, sometimes you want to combine two strings yourself, so you might use:

    print 'Addition of above two numbers are:' + str(z)

Here we are using the str type as a conversion function.  Note that we
used parentheses, not the dot operator.  And notice that since print
only gets one item, it does not add a space.
