Read 4DD database with Python

Question

I try to read with Python a 4D database which is composed of 5 files (*.4DD, *.4DB, *.4DIndx, *.4DIndy, *.Match). I saw an interesting package python4DBI 1.0.4 but I can't manage to use it correctly.

The example below doesn't work and returns "ConnectionRefusedError: [WinError 10061]":

 # Instantiate a connection object
    con = python4DBI()

    # Authentication
    con.connect(user='theUser', password='thePassword')

    # Check if the socket is connected
    if con.connected() is True:
        # Do stuff
        pass

    # Close the socket connection
    con.close()

Have you got an explanation ? What parameters I have to enter for user and password ? Do I need to install something more, like for example SQL server?

Full beginner in database, but would like to learn...
