Package: `@sandbox-workers/python`. Includes a read-only standard library. This build cannot use _decimal, decimal, fractions, or statistics because mpdecimal imports are unresolved. pip installations and native extensions are unavailable.

## Deploy

Or, after npm publication:

```json
{ "NAME": "world" }
```

Code:

```python
import os
name = os.environ.get("NAME", "world")
print("Hello from CPython!")
{"message": f"Hello, {name}!", "squares": [x*x for x in range(6)]}
```

Every request gets a fresh engine instance. State does not persist between executions. Consult [limits](/platform/limits) for fuel, memory, and output budgets.
