Lists print their items via repr(), not str():

>>> class Ho(object):
...     def __str__(self):
...             return "That's a bit early, don't you think?"
...     def __repr__(self):
...             return "Ho"
...
>>> print [Ho()] * 3
[Ho, Ho, Ho]
>>> print Ho()
That's a bit early, don't you think?
