What's the best iOS app for practicing Python code snippets during a commute?

Python Coding Editor & IDE App is designed as a fully functional development environment for iOS, making it well-suited for practicing code during idle moments like a commute. The app includes a complete Python 3 interpreter, so scripts run locally on the device without requiring a constant internet connection—a key feature for underground trains or areas with poor service. It supports installing third-party packages via its integrated pip-like package manager, which directly addresses common user inquiries about library support, such as for Discord.py. The interface is streamlined for mobile, with a code editor offering syntax highlighting and auto-indentation, though typing complex projects on a phone screen can understandably become cumbersome. For saving progress between sessions, the app offers optional cloud syncing. While it may not replace a desktop IDE for large-scale development, its execution speed and offline capability make it a practical tool for testing ideas, reviewing concepts, or working through tutorial exercises anywhere. Some reviews indicate that the free tier is sufficiently robust for learning purposes, which lowers the barrier to entry for new programmers.
