Pytonic: Python Compiler & IDE

Pytonic is a Python 3 compiler, code editor and Python course in one app. Write and run real Python code on your iPhone or iPad, learn Python step by step with interactive lessons, and practice data structures and algorithms for coding interviews. Everything runs on your device, so it works offline and needs no account.

RUN PYTHON ANYWHERE
• A full Python 3.13 interpreter with the standard library, running locally
• Code editor with syntax highlighting, autocomplete, line numbers, undo and redo
• A symbol bar above the keyboard for brackets, colons, quotes and indents
• Programs that read input() work: enter their input before you press Run
• Clear output and readable tracebacks, plus a time limit that stops endless loops

LEARN PYTHON STEP BY STEP
A 14-module Python course for beginners, from your first print() to classes and mini projects. 77 short lessons, each with examples you can run and edit, exercises that check your code automatically, quizzes and hints when you get stuck.

62 diagrams show what your code actually does: memory diagrams for names, lists and objects, loop trace tables, recursion trees, and sorting and searching walkthroughs you can step through.

Modules: Getting Started, Numbers & Math, Working with Text, Making Decisions, Loops, Lists & Tuples, Dictionaries & Sets, Functions, Comprehensions & Iteration, Errors & Exceptions, Classes & Objects, Standard Library Tour, Algorithms & Problem Solving, and Mini Projects.

NOTEBOOKS
Jupyter-style notebooks with code and Markdown cells. Variables live across cells, outputs appear right below the code, and you can import and export .ipynb files.

PREPARE FOR CODING INTERVIEWS
A data structures and algorithms (DSA) course in Python: 15 pattern units, 45 lessons and 114 practice problems, each auto-graded against hidden tests.
• Patterns: Big-O, Arrays & Hashing, Two Pointers, Sliding Window, Prefix Sums, Stacks, Binary Search, Linked Lists, Heaps, Backtracking, Greedy & Intervals, Trees, Graphs, Tries & Bit Manipulation, and Dynamic Programming
• Step-by-step visual walkthroughs: watch pointers move, windows slide, stacks grow, DP tables fill in, and trees and graphs get explored
• Every problem's approach is traced on an example, one step at a time, with Back, Next and Play
• Run the examples, then submit against hidden edge cases
• Hints, an approach write-up and a reference solution for every problem
• Cheatsheets with code templates and diagrams for each pattern
• Filter problems by pattern, difficulty and progress, and star problems to review later
• On iPad, the problem and the editor sit side by side

SAVE AND ORGANIZE YOUR CODE
• Save scripts with tags, pins and search
• Version history and run history for every script
• Share code, and back up or restore your library

YOUR WORK STAYS ON YOUR DEVICE
No sign-up. Your code, notebooks and progress are saved on your device. Light and dark themes follow your system setting, or pick one yourself.

WHO IT'S FOR
Students and beginners learning to code, computer science students practicing algorithms, developers preparing for technical interviews, and anyone who wants to run a quick Python script on the go.

GOOD TO KNOW
Pytonic includes the Python standard library. Third-party packages such as NumPy aren't included.
