Python ADO + ODBC function -


i writing small module transfer m$-access sqlite (database needs portable), i'm struggling in interpreting error message follows code (and of course work). 

import pyodbc import win32com.client  def ado(db, sqlstring='select * table', user='admin', password=''):     conn = win32com.client.dispatch(r'adodb.connection')     dsn = ('provider = microsoft.jet.oledb.4.0;data source = ' + db +  ';')     conn.open(dsn)     rs = win32com.client.dispatch(r'adodb.recordset')     rs.open(strsql, conn, 1, 3)     data = rs.getrows()     conn.close()     return data  def odbc(db, sqlstring='select * table', user= 'admin', password=''):     """create function connecting access databases."""     odbc_conn_str = 'driver={microsoft access driver (*.mdb)};dbq=%s;uid=%s;pwd=%s' % (db, user, password)     conn = pyodbc.connect(odbc_conn_str)     cur = conn.cursor()     cur.execute(strsql)     data = list(cur)     conn.close()     return data  if __name__ == '__main__': # unit test            db = r'c:\pyodbc_access2007_sample.accdb'     sql="select * customer orders" ## tables: 'customer orders', 'physical stoks','prodplans'     data1 = ado(db,sql)     data2 = odbc(db,sql)

from ado function error:

and odbc function error:

any idea's on how read this?

your connection string recognizes mdb access files. there connection string mdb , accdb files in pyodbc.
