Python Flask Tutorial: Full-Featured Web App Part 12 - Custom Error Pages

In this Python Flask Tutorial, we will be learning how to create custom error pages. We will be creating new error blueprints from scratch so that we can see how easy it is to add different sections to our application now that we are using blueprints. Once we are finished, we will have custom error pages for our 403, 404, and 500 errors. Let's get started...

I just completed this series and I coded the app as Corey was demonstrating in the videos. One very IMPORTANT thing I want to point out is this series has about 12 hours of solid learning content (guessing on the hours). With that said, I'm sure there were at least 10 times the amount of research and preparation hours that went into putting all of this together. To all of the satisfied viewers out there, do your part and send Corey some coin! One time donation, regular Patreon, or whatever. We've got to keep this guy motivated on continuing to put out home-run hitting series like this. ... pretty please. :-). I am a Patreon and automatically donate every month. It's not a lot, but if a lot of viewers give a little, I'm sure he would appreciate it.

I still can't believe that is course was free. Thanks for your incredible work Corey, you really helped me understanding Flask and Python.

I STOOD UP AND APPLAUD! Wow. That was like watching a Netflix Series - but with an outcome... it was so satisfying to see a running Python App. YOU ARE THE MAN! Thank you so much, Corey.

Thank you Corey, 5 years later and people are still benefitting from your wisdom. It truly takes a gifted teacher to break down challenging concepts like this and make them easily digestible.

So, I finally completed this whole tutorial. I would like to request you to please make videos on the below topic.
a) Unit testing and
b) And deployment of flask/Django applications.

You're creating really good content. Keep working hard.

First of all I want to take a moment to THANK YOU for putting your time and effort to make this series.

I started out learning Python around six months back. Before that I was writing code (professionally and personally) in Java for the better part of last 7 years. Like God's gift, I came across this channel few months back and started with the Python fundamentals series. Then one series led to another and six months after, today I code in Python at work (after almost 5 years of coding in Java professionally) and feel very passionately about it doing it and learning it.

I feel, the way you teach is the way programming should be taught. You have the perfect examples, the best explanation, great preparation and quality direction in your videos. I have recommended your channel to a number of my friends and colleagues and everyone has thanked me for that. Got to say that, you have a rare quality of connecting to a very diverse audience.

Even tough, I had started learning django couple of times, I could never finish the courses due to lack of all of the things that you excel at in those courses. However, I had no intention of learning Flask. But today after finish all the videos in this series I feel like great.
I know, all these sound cheesy, but I feel, I had to THANK YOU.

Thank you so much for making the tutorial vids. I've watched dozens of YT channels w/ Python tutorial vids, but your method of presenting information is the most clear, useful, and concise by comparison. Kudos!

[egreen]

Thank you so much Corey, coming from a php background, jumping from one tutorial to another, picking up pieces here and there, this series really help me put it all together. I truly appreciate, and I'm super excited to be a paid member, not so much for the perks, but in appreciation of your wonderful work.

Thanks for the amazing tutorial Corey! Really learned a lot on the basics of the skills required to successfully create and launch a web app using Flask. The course was very well paced and structured, you did not waste time explaining things that are more general python concepts but at the same time spent time providing a good description given the context we used them in the tutorial.

[fouroakfarm]

Amazing series you created and very generous of you to share it freely. I went from zero knowledge of Flask to ability to write a full app in just a day. Thanks so much

[this_timetraveller]

Cant get any better teacher than you, i have been following you since one year now.Thanks a lot for the gud work.

[tubalix]

Corey, you are a gifted instructor. I have seen many videos on Python & Co. and am impressed by your clear explanations and clean strain of thought. Amazing!! Thanks!!

[ZOOSnippets]

I really enjoyed these tutorials. You did a really nice job en explained all stuff
thoroughly. I would really like a continuation of this series with topics as 1) comment system (maybe like/dislike functionality), 2) admin page features, 3) content management system, 4) unit testing and 5) search whole website tool. Just some thoughts. Keep up the good work!!

[EMPured]

Thanks a lot for the flask series! I coded along every time and I learned a lot. I tend to start things and then give up because it bores me faster than expected. But this series got me excited every time after completing a segment and I looked forward to start with the next video.

[Cytzix]

Corey, thanks so much for this series. It was so motivating and interesting watching your flask tutorial and learning from you. I am sure I would have dropped this the idea of learning python - flask if I didn't find your tutorial...

Today is the 31th and I am proud to say I have finished all parts and will start the development of my own Web App in 2019!

I wish you a happy new year!

[mishaqman]

Corey Schafer! Believe my words. You are amazing! Cannot believe you are creating such amazing content on Youtube for free. I am quite new to programming, especially Flask, and no one could have better explained it! You are a rockstar. Period!

[willemhimpe]

this was an amazing journey !! Thanks a lot Corey, I will definitly go to your patreon page to support more awesome tutorials!!

[johnconteh]

Thanks Corey, I have learnt a lot from this series of Flask app development. What a great teacher you are.

[adamn]

All the best Corey! You really are a gifted programmer and a great teacher. Marvelous work!

[afafsgdchdhdg]

Corey I thank you from the bottom of my heart. I could not have afforded to take a course like this and even if I took one I don't think they would teach me this much. May you excel in your career
