Use the StringIO/cStringIO modules.  (cStringIO is written in C,
theoretically making it faster, but unless you're writing lots of data it
probably won't make a significant difference.

Example:

from StringIO import StringIO
output = StringIO()
print >>output, 3.14*r**2
print >>output, 'blah blah blah'
str_value = output.getvalue()
