# Python Playground Run Python code in an isolated playground directory for testing and experimentation. ## Instructions 1. First, ensure the playground directory exists. If the `playground` directory doesn't already exist, run `mkdir playground`. 1. Use the Write tool to create the Python file at `playground/test.py` 1. Run with: `uv run playground/test.py` to test cpython behavior or `cargo run -- playground/test.py` to test monty behavior IMPORTANT: Use separate tool calls for each step - do NOT chain commands with `&&`. This allows the pre-approved commands to work without prompting. ## Example workflow Step 1 - Create directory if it doesn't already exist (Bash, already allowed): ```bash mkdir playground ``` Step 2 - Write code (use Write tool, not cat): Write to `playground/test.py`: ```python def foo(): raise ValueError('test') foo() ``` Step 3 - Run script (Bash, already allowed): ```bash uv run playground/test.py ``` ## Guidelines - The `playground/` directory is gitignored - Use a different file name for each test you want to run, give the files recognizable names like `test_value_error.py` - Use `uv run ...` to run scripts (uses project Python) - Or, `cargo run -- ...` to run scripts using Monty - Use Write tool for creating files (avoids permission prompts) - Run mkdir and uv as separate commands (not chained) - do NOT delete files from playground after you've finished testing
