Love that you walk through completely end to end - from installing prerequisite tools all the way through. Sometimes the initial install/setup stuff is the hardest part

virtualenv install for windows 10:
open up terminal in VS Code
1)pip install --upgrade virtualenv press enter
2) virtualenv env press enter
3) virtualenv \path\to\env\Scripts\activate press enter

For windows 10 you must use 'virtualenv ...' to run commands. Example: 'virtualenv \path\to\env\bin\activate' to activate.

I like the pace and the fact that there's no fluff words. Though, this isn't really a 'learn Flask' video, this is a "Type as you follow along as he *kind of* explains what's going on" type video.

Exactly what I needed! Covers complete flask basics for a simple CRUD application (Todo list) in 45 minutes.

Hello all. I figured out why this doesn't work. SQL alchemy has been updated since this video Tutorial. The problem is nobody explains it properly, but I will give you a quick fix. Instead of Running the db.create_all() command in the terminal Initialize the Database in your code after your Database Models classes have been setup:
with app.app_context():
db.create_all()

Basically, put this in your Flask app under the Db.Model classes. Make sure to indent properly and run your flask app one time. It should create the database (also check your instance folder for the db file). Then comment it out. You can run other SQL commands under the with statement if you need info on what's in your database file.

15 minutes in and he's already showing us how to work with databases. THIS GUY IS AWESOME

Thanks, this was exactly what I needed to get going with flask :)

Holy cow! This has been a lifesaver. I got about a quarter way through Cory Schafer's flask series and was completely lost. It's a bit hard to tell the essentials apart from stylistic design choices and I just felt like I was struggling to memorize huge chunks of code. This tutorial is way more bare bones; but that's a great advantage it has over other tutorials as I'm really getting the no-nonsense core ideas about flask out of this. Great stuff!

This is a god send! Have a task using Flask and struggled for 2 weeks just to setup the virtual environment, thanks so much :) Liked and subbed!

Great tutorial about a great framework. The video nudged me into the right direction. I just finished a contract management app for our leasing business within less than a week. Thanks!

Thanks a lot, it was truly enjoyable to follow your tutorial step by step to dive into Flask. Your voice is really nice to hear. Now, I feel like I have all the basics to build my own app. You did a great job.

Really nice tutorial. I'm a software developer who works in embedded systems/automotive and for my work I use C programming language for 99% of tasks and for the rest of tasks I use python. I enjoid this crash course.

The voice was instantly comforting - thank you for being my educator on flask in less than an hour!

Great tutorial, my friend! I have some experience with Django and yesterday I had to to build a simple crud application and Flask fitted well. Keep it up! 😁

Wow, it was so easy explained. I believed that the topic is really difficult, but thanks to you, I understood everything. Thank you!

[someoneokay]

Really good tutorial. I am a beginner in flask and I must say the lecture is really insightful covering all the topics in one go.

[jackcardozo]

Glad I stumbled on your tutorial. I followed along for a couple of hours. Thanks so much!

I'm just starting Python and I'm already loving this language. This is so much more fun than PHP.

This tutorial is simply genius mate, you not only explain the very basics from a Flask app but the actual deployment to Heroku too. Probably one of best tutorials ever. Respect!
