## Sessions

```python
class Sessions()
```
Sessions allow you to run code at specific times of the day. It is a collection of Session objects.
Sessions are sorted by start time. The sessions object is an asynchronous context manager.

|**current_session**|**Session**|The current session.|None|

### Methods:
|Name|Description|
|---|---|
|**add**|Add a Session object to the sessions list.|
|**remove**|Remove a Session object from the sessions list.|
|**find**|Find a session that contains a datetime.time object.|
|**find_next**|Find the next session that contains a datetime.time object.|
|**check**|Check if the current session has started and if not, wait until it starts.|

#### \_\_init\_\_
```python
def __init__(*sessions)
```
Create a Sessions object.
#### Arguments:
|Name| Type               | Description                 | Default           |
