Besides using the type() function you could also use the types module and the isinstance() function: >>> l=[] >>> s='' >>> import types >>> isinstance(l, types.ListType) 1 >>> isinstance(l, types.StringType) 0 >>> isinstance(s, types.StringType) 1 >>> isinstance(s, types.ListType) 0 Hmm, I guess TIMTOWDY _sometimes_ applies to Python :-). -- Evgeny.
