Heres one option using the [c]StringIO module:

Python 2.2.1 (#34, Apr  9 2002, 19:34:33) [MSC 32 bit (Intel)] on win32
Type "copyright", "credits" or "license" for more information.
IDLE 0.8 -- press F1 for help
>>> d={'A':45.10, 'F':56.50,}
>>> from cStringIO import StringIO
>>> sio = StringIO()
>>> for item in d.iteritems():
	sio.write('%s%.2f' % item)

	
>>> sio.getvalue()
'A45.10F56.50'
>>>
