## Evaluation Prompt

````text

# Task
Using https://docs.cdp.coinbase.com, complete the following task:

Using the Coinbase Payments Python SDK, build me a script that:

1. Install the official Coinbase Payments Python SDK (pip install)
2. Creates a new *****net wallet using the SDK
3. Funds it from the *****net faucet (if available) using the SDK
4. Prints the wallet address and balance as JSON

You MUST use the official Coinbase Payments Python SDK — do not make raw HTTP/REST calls. Use *****net/sandbox mode for all operations. 

## Execution
After creating the script, run it to verify it works:
```bash
cd /home/daytona/app && python <your_script>.py
```

The script should print output to stdout. If there are errors, debug and fix them until it runs successfully.
