Learn Python vs CS++ Python IDE

Learn Python from your first line of code to building real applications: 168 courses and 4,020 lessons covering the entire language, plus 12,105 practice questions to prove you actually learned it. No prior programming experience needed. Every concept starts from zero and builds up with worked code examples you can read, understand and reuse. WHAT YOU WILL LEARN Python Fundamentals — syntax, variables, data types, operators, conditionals, loops, functions, scope, and error and exception handling. Data Structures — lists, tuples, dictionaries, sets, comprehensions, slicing, and the built in methods you will use every day. Object Oriented Programming — classes, objects, inheritance, polymorphism, encapsulation, magic methods, and when object oriented design is the right choice. Files and Data — reading and writing files, CSV and JSON handling, regular expressions, dates and times. Web Development — Django, Flask and FastAPI, requests, routing, templates, and web scraping with BeautifulSoup and Requests. Data Science and Machine Learning — NumPy, Pandas, Matplotlib, and an introduction to scikit learn, TensorFlow and Keras. Advanced Python — decorators, generators, iterators, context managers, lambda functions, threading, multiprocessing and asynchronous programming. Specialised Topics — Tkinter for desktop interfaces, SciPy, automation scripting, cryptography basics and API integration. 12,105 PRACTICE QUESTIONS Every one of the 168 courses has its own question bank, roughly three questions per chapter. Sessions are ten questions, four options each. Three timed difficulty levels: beginner 30 seconds per question, intermediate 20, expert 10. A session runs 5:00, 3:20 or 1:40. Pass at 70%. Filter by level, by attempted or untried, and by your best score, so practice goes where you are actually weak. Every attempt is saved permanently, so you can watch a topic go from 40% to 90%. PYTHON INTERVIEW PREPARATION 25 roles with 100 questions each — 2,500 in total — covering junior, mid, senior and staff Python, backend, Django, Flask and FastAPI, data engineering, data science, machine learning, MLOps, NLP, computer vision, QA automation, DevOps, SRE, application security, fintech, embedded and IoT, game tools, quant, cloud, full stack and RPA. Timed, scored and saved like every other session, so you can practise a role and come back to beat your own result. LEARN OFFLINE Download any course for offline reading. Lesson text is stored on the device and stays readable with no connection; images still need network. Anything you open is cached automatically. The Downloads manager lets you remove a course in one tap. PROGRESS, STREAKS AND CERTIFICATES Mark lessons complete and watch the completion percentage climb on every course. The Continue card returns you to the exact lesson you left. A daily reading streak counts every day you study, with an optional reminder that is off by default. Finish every lesson in a course and pass its quiz at 70% or above to unlock a certificate you can share as an image. BUILT FOR LEARNING ON A PHONE Short lessons you can finish in a commute or a lunch break. Code you can actually read — syntax highlighted, horizontally scrollable, copyable in one tap. Full text search across all 168 courses. Bookmarks and history. Light, dark and system themes, an in-reader toggle, adjustable font size, navigation placement options and proper tablet layouts. No account required to start. WHO IT IS FOR Complete beginners writing their first program. Students who want a clearer second explanation. Self taught developers building toward a first job. Professionals using Python for data analysis or automation. Candidates preparing for Python interviews. Developers coming from another language. Open the app, read one lesson, answer ten questions. Questions, corrections or a topic request? Email mail@ehsanur.com — we update the app based on what learners ask for.

CS++ Python IDE is a fully offline Python editor for iPhone and iPad, built for students learning to code. Write and run real Python 3 — including turtle graphics and multi-file projects — and work through 75 autograded challenges from the 10-unit Intro to Python catalog, all on-device. No account. No ads. No tracking. No internet required. WHAT'S INCLUDED • Free-form Python playground — write and run any Python code • On-device Python 3 runtime (Skulpt) — no install, no server, no network access • Interactive console with inline input() prompts • Turtle graphics drawn on a dedicated Graphics tab • Multi-file projects — add a helper.py tab and "import helper" just works • 15 starter templates: Hello World, variables & math, if/elif/else, for and while loops, functions, lists, dictionaries, strings, FizzBuzz, turtle graphics, random & math, statistics, CSV data, and more • Format, Abort, auto-saved code, and a run-time cap for infinite-loop protection UNIT 1 IS FREE FOREVER Unit 1 — Getting Started with Python is unlocked at install, and the free-form Playground is free forever too. Try the editor, solve real autograded challenges, and decide if the rest is worth $9.99. UNLOCK FULL INTRO TO PYTHON — $9.99 ONE-TIME A single in-app purchase unlocks all 10 Intro to Python units (75 autograded challenges): Unit 2. Variables & Data Types Unit 3. Operators & Expressions Unit 4. Strings Unit 5. Booleans & Conditionals Unit 6. Loops & Iteration Unit 7. Functions Unit 8. Lists Unit 9. Dictionaries Unit 10. Files, Tuples & a Final Project Pay once, keep forever. Restores on any device signed in to the same Apple ID. No subscription. Future content updates included. PYTHON FEATURES SUPPORTED Core Python 3: numbers, strings and f-strings, if/elif/else, for and while loops with break and continue, functions with default parameters, recursion, lists and list comprehensions, dictionaries and dict comprehensions, slicing, enumerate(), and interactive input(). Bundled modules include turtle, random, math, statistics, csv, and io. OUT OF SCOPE (not in the on-device runtime) No pip installs, no C-extension packages (NumPy, pandas), and no network access. Writes to real files aren't supported — build text in memory with io.StringIO instead. This is a learning IDE, not a deployment environment. PRIVACY Everything runs on your device. The app does not require an account, does not collect personal information, does not include analytics or advertising, and does not track you across apps. Your code stays on your device. See csplusplus.com/privacy for details. WHO IT'S FOR • Students learning Python without a desktop setup • Intro to Python classes that want practice on iPads and iPhones • Teachers who want a tablet-friendly tool for in-class practice • Self-learners working through Python on the go For lessons, Parsons problems, quizzes, flashcards, and the full browser Python IDE, visit csplusplus.com.
