Complete 2026 Python Bootcamp: Learn Python from Scratch
4.6
A 17.7 hour Python starter from the CodeWithHarry YouTuber, with 110 lectures that run from variables through Flask, Git and an AI video project, backed by nearly 18,000 reviews.
Best for: Complete beginners who already like Harry's YouTube style and want a structured, paid version with projects and a taste of Flask.
Pros
Cons
-
- Clear, bite-sized explanations of the basics that reviewers say got them writing code on their own
- Real projects, including a Flask web app and an AI video generator, so theory gets applied right away
- Refreshed in February 2026 and includes a section on coding with AI tools like Copilot and Cursor
- Active Q&A section, according to one reviewer, plus 19 caption tracks
-
- Pace speeds up in the advanced and project sections; several reviewers say they couldn't keep up
- Some concepts appear in exercises before they are taught, and the external libraries section is thin
- Flask, Jinja and Git take about a quarter of the runtime that one reviewer wanted spent on deeper Python
2
Python PCEP: Become Certified Entry-Level Python Programmer (2026)
4.6
A tight 4.5 hour Python primer built around the PCEP entry-level exam, with a quiz per module, a timed mock test in the real format and six months of PyCharm Pro thrown in.
Best for: Beginners or lapsed Python users who want the PCEP certificate fast and a structured syllabus rather than a sprawling bootcamp.
Pros
Cons
-
- Five modules map directly onto the PCEP-30-02 exam blocks, each closing with a quiz
- Mock exam mirrors the real format, passing grade and time limit; one reviewer reports a first-try pass
- Short, chunked lessons that reviewers call easy to understand and easy to rewatch
- Six months of PyCharm Professional included via JetBrains, plus a content refresh in August 2026
-
- In-video coding widget shows only two lines at a time and scrolls badly, reviewers say
- Long lists and dictionaries go by too fast to type along, with no copy-paste text provided
- Practice test and final test are identical, and some quizzes jump ahead of the lessons for true first-timers
3
RESTful Web Services with Spring Framework - A quick start (2024)
4.6
A free three hour Spring Boot taster that takes Java developers from an empty project to working GET, POST, PUT and DELETE endpoints with validation and error handling.
Best for: Java developers who have never used Spring and want a working REST API in an afternoon before committing to a long course.
Pros
Cons
-
- Free, and refreshed in August 2024 rather than left at its 2018 publish date.
- Reviewers praise short videos that get to the point, with just enough detail on each annotation to code along.
- Covers the full request cycle: GET, POST, PUT, DELETE, query and path parameters, JSON and XML responses, validation.
- Only 82 of 4,822 reviews are one or two stars, and students say the whole thing takes a day or two.
-
- No quizzes, coding exercises or assignments; the only practice is coding along with the videos.
- Skips databases, middleware and security apart from a six minute bonus section.
- Assumes you already know what REST is; one reviewer says it is not for people starting from zero.
4
Flutter Masterclass - Your Complete Guide to App Development (2026)
4.3
A short, cheap six-hour Flutter and Dart primer for total beginners, and the only mobile app course among the Software Development picks it sits beside.
Best for: Complete beginners who want a quick, low-commitment taste of Flutter before buying a much longer bootcamp.
Pros
Cons
-
- Clear explanations at a pace beginners in the reviews say is easy to follow
- Short at six hours, so it fits into a weekend
- No prior coding needed and refreshed in March 2026
- Cheaper and far shorter than a full Flutter bootcamp for a first look
-
- More than one reviewer says the audio volume is too low
- Lessons are taught from PDFs rather than live coding in an IDE, which one two-star reviewer found unimpressive
- Only 20 lectures in one section, no quizzes or exercises, and reviewers wanted more of Flutter covered
5
Building Internet of Things Projects with Arduino IOT Cloud (2022)
4.5
A five hour, project first walkthrough of the Arduino IoT Cloud with MKR boards, praised for patient teaching but recorded on the platform's beta version.
Best for: Arduino hobbyists with an MKR WiFi board who want cloud dashboards, webhooks and IFTTT without writing much code.
Pros
Cons
-
- Builds real projects, including a motion alarm that calls a phone and a self regulating temperature system
- Reviewers call Lee Assam a patient, clear communicator who explains each step and how the parts fit
- Short at under five hours and 58 lectures, so the whole thing fits in a weekend
- Covers dashboards, webhooks and IFTTT integration, not just board setup
-
- Recorded on the beta Arduino IoT Cloud; reviewers say menus and names no longer match the videos
- Needs an MKR WiFi 1010 board and basic Arduino and C knowledge despite the beginner label
- Some reviewers report unanswered questions in the Q&A and want ESP32 alternatives covered
