QPython3

QPython3: Run Python scripts directly on your Android device — no PC required.

QPython3 turns your smartphone or tablet into a fully functional Python development environment. Whether you are a student learning to code, a data analyst running quick scripts, or an automation enthusiast testing ideas on the go, this app eliminates the need for a desktop setup. Execute .py files, manage packages, and debug code entirely from your mobile interface.

Core Development Environment

• Built-in Python 3 interpreter — supports standard library modules including os, sys, math, and json.
• Interactive console — type commands line-by-line for immediate execution and result display.
• Script editor — syntax highlighting, line numbering, and undo/redo for .py file editing.
• File manager — browse, open, rename, and delete Python scripts stored locally or on external SD cards.

Package Management & Extensions

• Pip integration — install third-party libraries such as requests, numpy, matplotlib, and flask directly from the app.
• Pre-installed packages — pip, setuptools, and wheel come ready for immediate use.
• Offline-friendly mode — scripts run without active internet after initial package downloads.

Script Execution & Debugging

• Run button — one-tap execution of the current script with real-time output in the console.
• Error traceback display — exact line numbers and error types shown for quick debugging.
• Stop execution — force-terminate a running script if it enters an infinite loop or hangs.
• Background execution — scripts continue running even when you switch to another app (requires notification permission).

Integrated Development Tools

• Code completion — automatic suggestions for built-in functions, user-defined variables, and imported modules.
• Quick search — find strings or variable names across all open scripts.
• File encoding detection — automatically handles UTF-8, ASCII, and other common encodings.
• QR code scanning — import scripts from QR codes shared by other QPython users.

File & Project Management

• Project folders — organize related scripts into named directories for course assignments or personal utilities.
• Export/Import — share .py files via email, cloud storage, or direct Bluetooth transfer.
• Template library — start with pre-written code snippets for common tasks (HTTP requests, file I/O, regex matching).

Performance & Compatibility

• Runs on Android 4.0+ — works on devices as old as Ice Cream Sandwich.
• Low memory footprint — uses approximately 50 MB RAM during idle state, scaling up with script complexity.

• Multi-threaded execution — supports threading and concurrent.futures modules for parallel tasks.

• Execute Python 3 scripts on Android

• Install pip packages directly
• Interactive console with autocomplete
• Syntax-highlighted code editor
• Offline script execution supported
