[storm] This is a noob question: storing lists

[chandramouli s]

What I would like to do is store a set of data values, 400 or so in a
sqlite database (instead of a flatfile as it is normally done). And I
tried to run following  the examples, but I wonder if the list storage
is right. Any help is much appreciated

The program:
############################################################

from storm.locals import *
class Personner(object):
  __storm_table__="personner"
  id= Int(primary=True)
  name=Unicode()
  marks=List()

database=create_database("sqlite:///fort")
store=Store(database)
store.execute("CREATE TABLE IF NOT EXISTS personner (id INTEGER
PRIMARY KEY, name VARCHAR,marks TEXT)")
for x in xrange(200):
  d=Personner()
  d.name=unicode(str(x))
  d.marks=[x,2*x,x-1,x*6] # d.marks=unicode(str([x,2*x,x-1,x*6]))
  store.add(d)
  store.flush()
  print 'success'

store.commit()
print 'done'
