Complete 2026 Python Bootcamp: Learn Python from Scratch

4.6
(17,941 reviews)
byHaris Ali Khan

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.

icon
Pros
icon
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

Python PCEP: Become Certified Entry-Level Python Programmer
provider

2

Python PCEP: Become Certified Entry-Level Python Programmer (2026)

4.6
(12,609 reviews)
byAdrian Wiech

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.

icon
Pros
icon
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

Eclipse IDE for Beginners: Increase Your Java Productivity
provider

3

Eclipse IDE for Beginners: Increase Your Java Productivity (2026)

4.6
(6,969 reviews)
byChad Darby

A free, one-hour walkthrough of the Eclipse IDE from Chad Darby, built for Java developers who already know the language but have never touched the tool.

Best for: Java developers who know the language but need Eclipse basics fast.

icon
Pros
icon
Cons
    • Free, and only about an hour of content start to finish
    • Covers install through debugging, refactoring, and JUnit tests in one course
    • Instructor Chad Darby gets consistent praise for clarity and pace
    • Reviewers say Darby is responsive to questions in the Q&A section
    • No downloadable code, so a couple of reviewers had nothing to follow along with
    • Assumes existing Java knowledge, so true beginners will be lost
    • One reviewer found the JUnit chapter noticeably dated compared to their install

Flutter Masterclass - Your Complete Guide to App Development
provider

Flutter Masterclass - Your Complete Guide to App Development (2026)

4.3
(306 reviews)
bySayman Creative Institute

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.

icon
Pros
icon
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

Building Internet of Things Projects with Arduino IOT Cloud (2022)

4.5
(498 reviews)
byLee Assam

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.

icon
Pros
icon
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
