How to insert null value into sybase with python

How to handle Sybase table with null value in Python

create table Account(

accountId varchar(12) not null,

rollup_indicator  char(1) null

)

when need to insert one row as ('038C08234', null)  (roolliup_indicator has null value)

sql= "insert into Account(accountId, rollup_indicator)  values(?, ?) "

in Python, when detect a value is None, we can't pass None to the sql statement, and there is no NULL variable, if pass 'NULL'  string as rollup_indicator value, the insert will not take effect, since rollup_indicator is char(1), 'NULL' is 4 characters.

I am  using sybpydb module and execute with cursor

cur.executor(sql, ('038C08234', 'NULL'))

Anyone has experienced  with inserting/updating null value in Python Sybase?  Thanks,

Bill
