Python Compiler

Python Compiler runs real Python on your Android phone and tablet. Not a remote service pretending to be one: a full CPython interpreter is built into the app, so your code runs on the device, offline, with the standard library available.

WRITE
- Syntax highlighting tuned for Python, not a generic text field
- Errors marked as you type, by the same interpreter that runs your code
- Auto-indent, bracket matching and auto-closing pairs
- A keyboard row for the symbols Python needs, which you can edit
- Snippets for the patterns you retype, including your own

RUN
- A real interpreter on your device: works on a plane, on the subway, anywhere
- The standard library: json, sqlite3, hashlib, re, datetime, math, zlib and the rest
- Console output and tracebacks side by side with your code
- Pick other Python versions when you want to compare behaviour across releases

UNDERSTAND
- Symbols: every class and function in the file, at a glance
- Abstract Syntax Tree: the parse tree your code actually produced
- Concrete Syntax Tree: every field and token, comments included

BRING CODE IN, TAKE IT OUT
- Open .py files from your device or any cloud drive
- Read code out of a screenshot or photo with on-device text recognition
- Share as a .py file, or export a syntax-highlighted image of your code

PREMIUM
Free accounts get daily runs. Premium removes the limit and unlocks formatting, OCR, the syntax trees, file import and export, extra fonts, custom snippets and keyboard keys, and image export without a watermark. Monthly, yearly, or a one-time lifetime unlock. The lifetime option exists because Python runs on your device and costs us nothing to serve.

PRIVACY
Your code stays on your device. It is only sent anywhere if you deliberately switch the runtime to a cloud version, which is never the default.
