You can reduce the config code if you pass the suffix without week part to parse and add "week" and "nextweek" inside the parse function to the provided URL, e.g.

```python
{
   'Stadtmitte': 'spk_Stadtmitte_print.php?ansicht=',
   ...
}

def parse_url(url, today):
    ...
    parse_week(url + 'week', canteen)
    parse_week(url + 'nextweek', canteen)
    ...
```
