Description

In this course you  learn how to interface a Python  application program with a PostgreSQL  database. Python has  various modules that you can use to  interact with databases. We will install psycopg2 connector module to enable us interact with PostgreSQL  database from our Python application.

We will be installing PostgreSQL Database Server and also create a new database and table that our Python application will interact with.

We will create the Python application frontend using Tkinter which is a built in Python module used to create graphical user interfaces . From tkinter module we will import ttk module which is a themed widget library that contains various types of widgets like buttons,labels etc that we can use to build the graphical user interface for our Python application. We will also import other bits and pieces from the tkinter module that our Python application will use.

Also we will create a database configuration file that twill be used to interact with the PostgreSQL  database from our Python application.
