Course Description

Python is a popular  and general purpose programming language that can be used for a variety of things like:

  • Web Development

  • Scientific Computing / Data Science

  • Machine Learning

  • Start-ups

  • FinTech and the Financial Industry

  • Software development

  • Mathematics

  • System scripting

  • Connecting to databases

Flask is a small and lightweight Python web framework that provides useful tools and features that make creating web applications in Python easier. It gives developers flexibility and is a more accessible framework for new developers since you can build a web application quickly using only a single Python file. Flask is also extensible and doesn’t force a particular directory structure or require complicated boilerplate code before getting started.

PostgreSQL is a powerful, open source object-relational database system . PostgreSQL allows to create databases and store data . It also allows you to interact with the data inside the database.

In this course we will create a web based application using Python and Flask and we will create and store objects inside a PostgreSQL  database that will interact with our web application's front end. We will also deploy the web application to the internet via heroku

Course is good. But failed to create database table. Separate section has to be provided to showing resolving conflicts between flask, python, conda, postgresql and conda setups. Overall it is a good course. Thanks.

By Aflah Tazakka on 12/12/2021

This is the course that i need right now, i need a quick but cover anything required to build and run a simple flask app. Thanks Bluelime, keep your amazing works!

By Bruno Moraes on 3/23/2021

I've leaned a lot, because I didn't know nothing about Flask until now. But, I've missed some configurations that could be import to learn. I've did all the things that the presenter did on a docker environment. It was very nice! So, the application was too base, we could learn a simple CRUD, and what commands to use and how to use it on Flask... but OK! It was good! Thanks a lot!

By Mahesh Solanke on 11/23/2020

It was amazing learning for me, I made a perfect app using flask. This tutorial is for the absolute beginner, I highly recommend this who is using flask 1st time. Thank you
