>>> session_1.kill()
```

```python
>>> session_1 not in server.sessions
True
```

Kill all sessions except the current one:

```python
>>> one_session_to_rule_them_all = server.new_session()
```

```python
>>> other_sessions = server.new_session(
...     ), server.new_session()
```

```python
>>> all([w in server.sessions for w in other_sessions])
True
```

```python
>>> one_session_to_rule_them_all.kill(all_except=True)
```

```python
>>> all([w not in server.sessions for w in other_sessions])

```

```python
