Learn Python vs Paralango

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.
