What you will learn

Python basics and real world coding framework - organizing code, logging, error handling, config file, unit testing

Why take this course?

Learn how to code and unit test Python applications in a real world project. Go beyond the basics by solving a practical use case step by step. This course is designed for Python beginners who want to transition for academic background to a real world developer role !

Course Project :

You will be building a Python application to read data from files and store the data into PostgreSQL database. You will be creating REST endpoints using which external users will interact with your application data. All the industry standard best practices in terms of logging, error handling, config file, code structuring will be used in the application.

Course structure :

Python (3.9) and PyCharm IDE installation
Python basics - Get started with basic Python data types including List, Tuple and Dictionary
Organizing code with Classes and Modules - Understand core concepts of classes and packages
Python logging - Implement logging using basic config and file config
Python error handling - Learn how to handle exceptions.
Python PostgreSQL database interaction - Understand how to read and write to PostgreSQL using psycopg2
Create REST API using Python - Learn to create APIs using Python Flask framework
Reading configuration from property file - Learn how to avoid hardcoding of configurable properties
Unit testing - Learn to test your application using unittest package
Unit testing - Learn to test your application using PyTest package

You will learn the above concepts by building a real world file processing application. No prior Python knowledge required.

Prerequisites :

Basic programming skills
Basic knowledge of SQL queries

Very useful course! Good basics for Python, postgres, REST, and unit testing. Sometimes it goes a little bit too fast, so I often paused and replayed parts to be able to follow along.

about unit testing module, course just covered too basics not even covering the test set up the teardown methods also no clear cut info on how does multiple test cases from multiple files can be triggered individually/in a group.

I enjoyed the hands-on aspect and everything worked as expected. The presenter knows what he is doing and conveyed it accurately. The small bite-sized chunks are ideal for learning.
