This only works with tuples, not lists.  The % operator with strings
requires tuples.  I'm not sure why the chose to make this limitation. 
The following code gives this error.
a = [1,2,3,4,5]
print (5*"%5i ") % a
Traceback (innermost last):
  File "<stdin>", line 1, in ?
TypeError: illegal argument type for built-in operation

However, it works fine if a is a tuple.
Thanks.

I want to print something, and then latter, print something else on the
same line.  I don't want to append to a string and then print the
string.
