Although I have never done so, I believe you can also store/manipulate objects in a database.
Has anyone ever worked this option?

For example, MyObjects={} l=["a","b","c"] for i in l: MyObjects[i] = MyClass(i) Then you can refer to MyObjects["a"] If all the operations on the objects are done to all objects in a batch, putting them in a list might work. Then you can use list iteration to access all of them: MyObjects=[] l=["a","b","c"] for i in l: MyObjects.add(MyClass(i)) then to process all the objects: for myObj in MyObjects: # do something with myObj Kent Matt Williams wrote: > Dear Tutor-list, > > I'm sorry for this appallingly dumb question, but I'm having a little > problem with objects. > > I've written a class, with some methods.
