Subclass tuple and do your own __str__:

$ python
>>> class mytuple(tuple):
...     def __repr__(self):
...             strings = [str(x) for x in self]
...             s = ','.join(strings)
...             return "(%s)" % s
...
>>> t = mytuple((2, 0.4))
>>> t
(2,0.4)
>>> print (2, 0.4)
(2, 0.40000000000000002)

// m
