It is clearly not a bug :-)
print x[0] gives the same result as printing str(x[0]), the value of x formatted as a string (rounded to a sensible number of places). x[0] at the command prompt gives the same result as printing repr(x), the representation of the text value as a string. When you do print on a tuple it doesn't recursively call str(), so you get the repr representations. You can get similar results with anything where the str() and repr() values are different. e.g. x = ( u'a', u'b') -- http://mail.python.org/mailman/listinfo/python-list
