This is more a python question than anything specific to the IBMi ...

Most of my experience is with VBA and ODBC. With those, I would access data by ...

Dim DBConn As New ADODB.Connection
DBConn.Open "<connection string here>"
SQL = "SELECT something FROM somewhere"
Set RS = DBConn.Execute(SQL)
someDBData = RS.Fields(0).Value

So, now I'm using Python with ODBC and trying to figure out how to do similar to above. However, there seems to be no equivalent to 'RS.Fields(0).Value?

Internet searching revealed this as the way to put it into a dictionary for easy access (this is the function I wrote to try it out and it does work) ...
def get_arinv_data(start_date, end_date):
#get data
sql = '''select <some stuff>
from <some file>
where somedate between '{0}' and '{1}' ''' .format(start_date.strftime('%Y-%m-%d'),end_date.strftime('%Y-%m-%d'))

#place returned data in dictionary
arinv_columns = [column[0] for column in cursor.description]
arinv_data = []
for arinv_row in cursor.fetchall():
arinv_data.append(dict(zip(arinv_columns, arinv_row)))

return arinv_data

Is this really the way? Is there nothing as simple as just accessing the fields directly of a returned recordset?
