in my config.py I do a

when I run my script I get 'module' object is not callable
db.ini

#from configparser import ConfigParser
import configparser
def config(filename='database.ini', section='gr'):
# create a parser
parser = configparser()
# read config file
parser.read(filename)
# get section, default to gr
db = {}
if parser.has_section(section):
params = parser.items(section)
for param in params:
db[param[0]] = param[1]
else:
raise Exception('Section {0} not found in the {1} file'.format(section, filename))
return db

def connect():
""" Connect to the PostgreSQL database server """
conn = None
try:
# read connection parameters
params = config()
# connect to the PostgreSQL server
print('Connecting to the PostgreSQL database...')
conn = psycopg2.connect(**params)
# create a cursor
cur = conn.cursor()
# execute a statement
print('PostgreSQL database version:')
cur.execute('SELECT version()')
# display the PostgreSQL database server version
db_version = cur.fetchone()
print(db_version)
# close the communication with the PostgreSQL
cur.close()
except (Exception, psycopg2.DatabaseError) as error:
print(error)
finally:
if conn is not None:
conn.close()
print('Database connection closed.')
if __name__ == '__main__':
connect()

'module' object is not callable
any ideas ?
thank you.

Answer 1

You have an error in your parser creation, see the ConfigParser examples:
An example of reading the configuration file again:
import ConfigParser
config = ConfigParser.RawConfigParser()
config.read('example.cfg')
In Python, a module is basically just a file, so if you want to use anything from this module, you have to specify what from the module you want. In your case, change the lines to
# create a parser
parser = configparser.ConfigParser()
This way, you are using the class ConfigParser from the module.

Answer 2

You can also use the follow to import the parser:
from configparser import ConfigParser
instead of
import configparser
I had the same issue as you and this worked for me.
