[2.5.1] Converting string to int?

Hello

I'm using the APSW wrapper to SQLite, and I'm stuck at how to pass
data from a dictionary to the database which expects an integer:

#array filled by reading a two-column text file as input
for (isbn,carton) in data.items():
#TypeError: int argument required
sql = "INSERT INTO books (isbn,carton) VALUES ('%s',%u)" %
(isbn,carton)

#Incorrect number of bindings supplied. The current statement uses
0 and there are 2 supplied. Current offset is 0
sql = "INSERT INTO books (isbn,carton) VALUES ('%s',%u)" %
(isbn,int(carton))

cursor.execute(sql,(isbn,carton))
==========

What is the right way to turn items from a dictionary into an integer
so as to match the column definition in the database?

Thank you.

Found it: Apparently, this wrapper uses a different placeholder and
takes care of conversion if needed:

cursor.execute("INSERT INTO books (isbn,carton) VALUES (?,?)",
(isbn,carton))
