varchar2(8000)

I need to create a table like this one:

             create table session (
                    id varchar2(40),
                    data varchar2(8000),
                    expiration_time timestamp
                )

unfortunately varchar2 has a limit of 4000 char. I tried CLOB, NCLOB but I can't use them because I need to pass it to pickle and pickle wants a tring as argument

|>> <http://newjosedev.sferacarta.com:8000/#>data *=*
pickle*.*loads*(*pickled_data*)*|
*TypeError: ('loads() argument 1 must be string, not cx_Oracle.LOB', <bound method Root.index of <sicer.BASE.controller.Root object at 0x8231f10>>)*

What kind of type can I use to avoid this? thank you,
