You don't, see the other reply.
You didn't say why you think you need this for, but I suspect
that you can solve your case by using a dict in one way or another:
{ somename: [1,2,3,4,5] }

If you have several different types of lists and need to handle them differently, then you might consider using class's that knows how to handle each type of list. Also, if the name is really part of the data, then you should store the name as a string with the list. class data1(object): def __init__(self, alist, name): self.list = alist self.name = name def data_type(self): print This is a data1 object class data2(object): def __init__(self, alist, name): self.list = alist self.name = name def data_type(self): print This is a data2 object list_a = data1( range(10), small list) print list_a.list print list_a.name list_b = data2( range(100), large list) def data_type(data): data.data_type() # don't need the name here data_type(list_a) # prints 'This is a data1 object' data_type(list_b) # prints 'This is a data2 object' You can also store a name with the list in a list if you don't want to use class's. alist = ['mylist',range[10]] print alist[0] # name print alist[1] # list Regards, Ron -- http://mail.python.org/mailman/listinfo/python-list
