# Is Connected

> Check whether the current sandbox session is actively connected via WebSocket using the Python SDK.

The `is_connected()` method provides a quick way to verify whether your current sandbox instance is actively connected to Fermion’s backend infrastructure.

This can be useful for checking the session state before running commands, writing files, or performing other operations that require an active connection.

***

### `is_connected() -> bool`

**Description:**\
Checks if the WebSocket connection to the sandbox is currently active.

***

**Parameters:**\
*None*

***

**Returns:**\
`bool` : `True` if the sandbox is connected, `False` otherwise.

***

### **Example**

```python theme={null}
import asyncio
from fermion_sandbox import Sandbox

async def main():
    sandbox = Sandbox(api_key="your-api-key")

    # Check initial connection state
    print(sandbox.is_connected())  # False

    # Create a new sandbox
    await sandbox.create(should_backup_filesystem=False)
    print(sandbox.is_connected())  # True

    # Disconnect from the sandbox
    await sandbox.disconnect()
    print(sandbox.is_connected())  # False

asyncio.run(main())
```
