This seems to be the best lecture as a starting point for web development. Other lectures often missed the big picture, but this is a lecture that puts a lot of effort into conveying the big framework so that you can become familiar with the details through practice. If you've been swept away by trivial content and distanced yourself from web development, I recommend coming back to this lecture!

I have been living a life far from web applications, but I had the opportunity to apply Flask to my work, so I took the course. I had fun learning about various intermediate-level grammars that I didn't know because I didn't use Python very often, and the following front-end/back-end lecture for blog clone coding was easy to understand, so I think I was able to finish it quickly. I plan to steadily create a hobby service on my own using this course. Thank you.
Python Flask framework
Python Intermediate

HTTP and RestAPI
This course is a full-stack course series for learning Python backend and web technology fundamentals. It is designed to cover everything from intermediate Python syntax essential for professional development skills (object-oriented programming, first-class functions, etc.) to Python backend and web technology basics (HTTP, etc.) using the easiest framework, Flask. Therefore, rather than briefly explaining simple framework usage, we explain all the essential background knowledge and related technologies that must be learned. This course is a special one created with maximum consideration for the learner's perspective, based on 8 years of teaching experience with 60,000 students while working in the industry, going beyond typical IT courses.
This course has been verified by many learners who have mastered it and continue to provide positive feedback. If any issues arise, it can be updated regularly as it has been.
This online course is designed for beginners, starting very easily at first, gradually increasing in difficulty, and quickly covering core features step by step and their practical applications. In contrast, that book is a reference book intended for experienced developers who want to look up detailed features of Flask.
Therefore, I recommend quickly learning and applying Flask's core features through the online course, and then using the following book as a reference.
The Fastest Flask & FastAPI for Full Stack, by Dave Lee from Fun Coding
.jpeg?w=960)
# I want to build a foundation in backend and full-stack technologies!
# Where should I start to learn full-stack technology?
After learning one programming language, start by creating a Rest API with backend development. The core technology of full-stack is backend. Python Flask is easy, so you can quickly understand backend and full-stack development overall.
In this course, you'll learn backend technology with Python Flask, and also utilize simple frontend technology to understand the overall structure of both backend and frontend. Additionally, detailed explanations for understanding web technology, intermediate Python syntax, from planning (MVP) to MVC patterns, and comprehensive content for implementing modern web technology are explained in detail.
I've created a summary of the fastest and most up-to-date full-stack roadmap as a YouTube video. If you refer to that video, you'll be able to understand not only this technology but also a roadmap that will enable you to develop web/apps on your own in a short amount of time.
# How much programming knowledge do I need to take this course?
This course, as well as the courses I create, are fundamentally designed to be the easiest among courses covering the same technology, allowing you to follow along step by step. However, since this course deeply covers backend fundamentals using Python-based Flask, it will be much more effective when you have moved beyond the beginner stage, are able to program in Python, and have the capability to resolve issues on your own through Google searches when problems arise.
I notice that the `<translate>` tags are empty - there is no Korean text between them to translate. The surrounding context shows: - Before: "가 있습니다. 백엔드 핵심 기본기를 꼼꼼히 쌓을 수 있도록단순 백엔드 API 사용법이 아닌백엔드 핵심 및 관련 기술, 파이썬 중급 기술까지 정리합니다!" - After: "특히, 본 강의는 개발자 커리어를 진지하게 준비하시는 분들을 위한 강의입니다. 따라서 백엔드에서 일반적으로 사용하는 관련 기술도 깊이 있게 다루" However, there is no text provided between the `<translate>` tags for me to translate. Could you please provide the Korean text you'd like translated?</translate></translate>
In particular, this course is designed for those who are seriously preparing for a developer career. Therefore, it covers in-depth the related technologies commonly used in backend development. It also covers intermediate Python syntax, databases (SQL and modern NoSQL), Python dictionaries (JSON format), and HTML.
Therefore, to ensure higher course satisfaction and effectiveness, if you are not familiar with related features and Python, we recommend taking this course together with the following 3 courses. (With the above course structure, after years of feedback verification, those who took courses sequentially starting from the Python beginner course had very high learning effectiveness and satisfaction.)
# Is it useful to learn backend technology with Python?
Recently, startups develop their business by quickly creating various services and then expanding the ones that receive good customer responses. Since Python has excellent productivity, it can dramatically minimize the time and manpower required for service development. Generally, good developers can handle multiple languages in addition to their main language, and Python is becoming a fundamental language that developers should be able to use.
# What is Python backend flask?
Python flask, along with Django, is a backend framework that uses the Python language. It is a technology widely used globally, even by recent startups. Flask is easy to learn, enables rapid backend implementation, and is suitable for learning key web technologies. Django takes a long time to learn due to its unique framework usage methods.
Flask in particular is an easy technology, but there are areas where it's difficult to find detailed information. This course is designed to help you build a solid foundation in Flask by utilizing as many different Flask syntax patterns as possible.
#We also explain the overall topics you need to know for web service development
In reality, developing web services professionally requires a fundamental understanding across all aspects of web service development, and there are things you need to know for modern web service development. To address this, I've included explanations in the course about web service planning and AB Testing, which were necessary when working as both a planner and developer in actual professional settings. Additionally, I'll explain the MVC pattern and HTTP protocol, which are essential basics for implementing web services.
I covered BTest in the lecture as well. I also explain the MVC pattern and HTTP protocol, which are fundamental knowledge needed for implementing web services.
#Can beginners do this too?
The most difficult IT lectures are teaching programming to those who have no programming knowledge at all. Even these people have learned not only programming but also crawling techniques through my Python Introduction and Web Crawling Basics Bootcamp course. If you are a reasonable person, it is fully possible. This lecture series is designed to help you gradually become familiar with all the necessary skills at the beginner level with appropriate difficulty.
I'll provide materials/code better organized than e-books, all included! From relevant IT background knowledge, grammar, practice problems, to detailed code - the materials alone are worth the course fee.
#Can I learn it systematically?
I'm creating courses that start from beginner level and gradually increase in difficulty all the way to becoming a full-stack developer, with detailed and systematic learning. To help you understand the relevant syntax and knowledge, I provide concise code with thorough explanations, and when needed, I explain computer science concepts on the spot, so you can build a solid foundation to become a great developer.

It's easy to get stuck in a small view and miss the broader scope, isn't it? I made it with that in mind, so I'm glad you noticed! Thank you😊

It's a good lecture. I'm more than 80% satisfied. The 20% who aren't satisfied... The lecture speed is slow in easy parts and fast in difficult parts. I had to keep adjusting the lecture speed in the browser. I think the speaker unconsciously speeds up in complicated parts. And it's not a fun coding, but a nagging coding. Haha. No matter how good the advice is, it doesn't seem good to repeat it too much. Except for these two things. I'm satisfied with everything. It's a good lecture. I recommend it.
I tried to keep the speed the same, but each person might have different difficulties... When I was listening to the lecture, I tried to cheer the students on, but they kept nagging me... Oh my, I'm glad you said it was a good lecture even in that kind of stance.

Hello teacher! Is it possible to skip FastAPI and only take the Flask course to go full stack??? My current company is operating a platform with Flask as the backend.
It is possible. However, since FastAPI has similar syntax to Flask while having some improved aspects, I think it would be good for you to organize and review it once in the future, even just for reference. Thank you!!
So would it be better to take FastAPI after Flask -> Frontend lectures??? My goal is to implement a full-stack service on my own later.
Sorry for the late response^^:; My apologies I think Flask and FastAPI have high correlation, so from a learning effectiveness perspective, Flask -> FastAPI -> Frontend would probably be better. If you learn FastAPI after getting familiar with Flask, you'll likely see many similar parts, so you'll get some repetition with Flask and be able to learn FastAPI quickly as well.

I think this is the best lecture series for those who study alone. It wasn't easy to learn backend technology on my own, but after watching this lecture, I felt like I was reading the 'flask standard'. It's an oasis-like lecture with a mentoring-like feel, detailed explanations, focus on understanding, and abundant materials. If you think of time as money, It's much more cost-effective to learn this lecture and learn additionally than to struggle and learn alone from the beginning. At the beginning of this year, I started with the instructor's introduction to Python with a light heart. It was a year when I felt that I could make something with my own hands by listening to all the lectures step by step. Now, I'm thinking that I want to develop seriously. ㅎㅎㅎ This flask lecture is also difficult for me, but I'll absorb it quickly and make it mine. Thank you this year and I'll thank you in advance next year!
Thank you so much for starting with the crawling lecture. It gives me a lot of strength. Above all, I congratulate you for making progress and achieving results as a developer this year. Starting with Part 1 of Full Stack, the difficulty level is not easy, but it covers the parts necessary for full stack and the parts that a developer should have. If you understand that you need to go deeper sometimes and try it several times, it will help you steadily learn new technologies deeply. I hope this will help you become a good developer? A competitive developer. Thank you.

After taking a few classes, you can't help but become a fan of the instructor. He is so thorough, and his lectures are also very well prepared. I am such a fan that I even bought the basic lectures. But among them, after taking this course, I felt like my horizons were broadened, so if you have been interested in Python or websites, I definitely recommend it.
Thank you for leaving such a great review. It means a lot to me.
