[Balin]

Hi all,
I have some problem with packege kinterbas for Firebird db connection
this is my code:

import kinterbasdb

class ConnessioneDB:
    def initialize(self):
        kinterbasdb.init(concurrency_level=1)
        con = kinterbasdb.connect(host='192.168.1.20',
database='/home/db/TEST.FDB', user='SYSDBA', password='masterkey) <--- E

    def testtable(self):
        cur = con.cursor()
        cur.execute("SELECT * FROM TEST")
        for row in cur:
            print str(row[0])

if __name__ == '__main__':
    xCon = ConnessioneDB()
    xCon.initialize() <-- ERROR 
    xCon.testtable()

use kinterbas.init(concurrency_level=?) to set the concurrency level
legally...why ? I'm try to set this value
kinterbas.init(concurrency_level=1)  but don't work...please help..this
is my first program. Thanks in advanced.Marco.Italy
