Learn Python

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 show up 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, no server round trip

• input() works: type answers while your program is running

• turtle graphics and matplotlib charts render right in the output window

• Download the runtime once (about 11 MB) and use the Python IDE offline, without internet

• Python 3 IDE with syntax highlighting, line numbers and multi-file projects

• 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 toward 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
