If code does not run
- Check the line number and message shown with the error.
- If the code never stops, check whether normal execution reached its time limit.
pip installand third-party packages are not supported. Confirm that the code only needs the bundled Python standard library.- Save the card, relaunch the app, and repeat the same steps.
If a breakpoint is skipped
Tap a line number in the editor and confirm that a red dot appears before starting Debug. Blank lines and comment-only lines are not executable, so execution cannot pause on those lines.
About code completion
Completion suggests local Python keywords, built-in functions, and symbols already present in the source. It does not use AI or send code to an external service.
Change the app language
Open Settings, then App Language. English is the default. You can switch the entire interface among English, Japanese, Spanish, French, German, Brazilian Portuguese, Simplified Chinese, Traditional Chinese, Korean, and Italian. Your card names and source code are never translated.
Reset sample data
Choose Reset to Samples in Settings to replace saved cards with the original samples. Copy any source you want to keep somewhere else before confirming the reset.
Contact
If the issue remains, include the device model, iOS or iPadOS version, app version, selected app language, reproduction steps, and error text. Never send source containing passwords, secret keys, or access tokens.
