Why do you want to do that?  The reason you haven't found an answer is
that it's almost certainly not the right solution to whatever problem
you're trying to solve.

   '\n'.join('%s: %s'%(k,v) for k,v in locals().iteritems())

(untested) does something like what you're asking but I don't
advise it.  You should probably use a dictionary object instead.
