Well, don't give up!  The approach is sound and I did say it was 
untested.  Here's a tested version with a few corrections. :-)

Cheers,

class Pump(object):
     def __init__(self, name, ptype, number):
         self.status = 0
         self.name = name
         self.ptype = ptype
         self.number = number

class C_Y(object):
      def __init__(self, plist):
           index = []
           for p in plist:
               self.__dict__[p[0]] = Pump(*p)
               index.append(p[0])
           self.index = index
      def showall(self):
           out = []
           for item in self.index:
                out.append( "%s: %r, %r, %r\n"
                            % ( self.__dict__[item].name,
                                self.__dict__[item].status,
                                self.__dict__[item].ptype,
                                self.__dict__[item].number ) )
           return  ''.join(out)


pumplist = [ ('p1', 'ob1', 0),
              ('p2', 'ob1', 1),
              ('p3', 'ob1', 2) ]
