About this app

Learn Python programming on your phone with a complete python course for beginners and a real Python 3 compiler and IDE that runs your code on the device. Write code in a built-in editor and run it instantly: input() works, and turtle drawings and matplotlib charts appear in the output. Made for complete beginners, students and developers preparing for a technical interview.

PYTHON COMPILER, IDE AND CODE EDITOR ON YOUR PHONE
• A real CPython interpreter runs your code on the device, with no round trip to a server
• input() works: type answers while your programme is running
• turtle graphics and matplotlib charts render directly in the output window
• Download the runtime once (about 11 MB) and use the Python IDE offline, without an internet connection
• Python 3 IDE with syntax highlighting, line numbers and multi-file projects

76 COURSES, 320 LESSONS
Levels A1 to C1: a Python course from complete beginner to advanced:
• Basics: variables, types, input, strings, lists, tuples, dictionaries and sets
• Control flow and loops, functions and arguments, modules, packages, pip and virtual environments
• Object-oriented programming: classes, inheritance, polymorphism, dataclasses and enums
• Error handling with try/except, logging, debugging, testing with pytest, type hints and mypy
• Files and pathlib, JSON and CSV, regular expressions, datetime, collections and itertools
• Advanced: comprehensions, generators, decorators, context managers, async/await, threading and pattern matching

• Data: SQLite, SQLAlchemy, NumPy, pandas, matplotlib and Plotly
• Web development with Flask, Django and FastAPI
• A first look at data science and machine learning with scikit-learn

PRACTICE THAT STICKS
• 60 coding missions: 20 easy, 20 medium and 20 hard
• 20 guided projects, one step at a time: query a SQLite database, parse logs with regex, write your own decorator
• Bug Hunt: find the bug in a short snippet, weighted towards the topics you miss
• Quizzes with explanations and a cheat sheet with 72 code examples
• Flashcards with spaced repetition so new terms stay with you

COMPETE AND KEEP GOING
• Weekly Code Duel: solve the week's problem and race the recorded run of a real learner
• World Coding Challenge: 3 global coding rounds every day
• Weekly League, XP, streaks and progress tracking

INTERVIEW PREP
• Interview questions with model answers
• AI Mock Interview: type your answers, get follow-up questions and a scored report at the end
