# Code Execution Fallback ## When to Use Use this pattern when `execute_code_sandbox` fails repeatedly (typically 2+ attempts) due to environment limitations, timeouts, dependency issues, or sandbox restrictions. ## The Pattern Instead of executing code directly in the sandbox, write the Python script to a file and execute it via shell: 1. **Write the script** using `write_file` 2. **Execute via shell** using `run_shell` with `python3 script.py` 3. **Clean up** (optional) remove the temporary file ## Step-by-Step Instructions ### Step 1: Write the Python Script ``` Use write_file to save your Python code: - Path: Choose a descriptive name (e.g., "process_data.py", "analyze.py") - Content: Your complete Python script with all imports and logic ``` ### Step 2: Execute via Shell ``` Use run_shell to execute: - Command: "python3 <script_name>.py" - Timeout: Set appropriately for your task (default 30s, increase if needed) ``` ### Step 3: Handle Output ``` - Capture stdout/stderr from run_shell - Parse results as needed - Optionally delete the script file after execution ``` ## Example ```python # Instead of this (which may fail): execute_code_sandbox(code="import pandas as pd; df = pd.read_csv('data.csv')...") # Do this: write_file(path="analyze.py", content=""" import pandas as pd import json df = pd.read_csv('data.csv') result = df.groupby('category').sum() print(json.dumps(result.to_dict())) """) run_shell(command="python3 analyze.py", timeout=60) ``` ## Tips for Success 1. **Include all imports** in the script file - the shell environment may differ from the sandbox 2. **Use absolute paths** or ensure working directory is correct 3. **Add error handling** to your script for better debugging 4. **Increase timeout** for long-running operations (default is 30s) 5. **Print structured output** (JSON) if you need to parse results 6. **Clean up temporary files** after successful execution to avoid clutter ## When This Helps - Sandbox has missing dependencies - Code execution times out in sandbox but would work in shell - File I/O operations are restricted in sandbox - Need to run external commands or system utilities - Complex multi-file projects that need proper file structure
