Did you read the documentation of fetchone?
fetchone is like fetchall except from the fact that the former returned
a row of data while the latter returned a list of rows of data.
Read the documentation of fetchone again:
http://docs.python.org/3/library/sqlite3.html#sqlite3.Cursor.fetchone
Take careful note of what it does when there is no more data to fetch.
I dont know why it copmains about:
TypeError: 'NoneType' object is not iterable
what object is supposed to have benn of None type? how do i check for
it?
Does the name "NoneType" give you a hint? Repeat after me:
"The type of **** is NoneType."
Take a guess what the **** should be. Then test it, in the interactive
interpreter:
type(****) # replace the stars with the object
and see what is printed.
# fetch those columns that act as lists but are stored as strings
cur.execute('''SELECT refs, visits, downloads FROM visitors WHERE
counterID = %s and host = %s''', (cID, host) )
data = cur.fetchone()
print( type(data) )
sys.exit(0)
i tried inserting a type function to notify me of the datatype of 'data'
but that didnt help too.
Still:

Unfortunately i still miss your point.
