Summary: str(a_tuple) == '(%s)'%', '.join(map(str,a_tuple))

Initial Comment:
This patch against Python 2.3.3 ensures that str is 
recursively applied to  
members of a tuple when called on a tuple.  
 
Currently (python 2.3 and 20040609 cvs HEAD branch  
too) repr is applied to the members of the tuple such  that  
>>> str((1,0.1))  
'(1, 0.10000000000000001)'  
  
With this patch:  
>>> str((1,0.1))   
'(1, 0.1)'  
 
This patch is easily transposable to cvs HEAD an to lists.

What if the tuple is ("1, 2", "3")?

The primary reason str(container) applies repr to the 
containees is so that contained strings are rendered 
unambiguously.  Debated ad nauseum many times on python-
dev over the years, with no good resolution.
