`policy` is a better variable name than `each`. Also, instead of creating `dict` using keyword args, could you create it using `{...}` syntax? Something like:
```python
policy = { 'args': {'at': self.autoscale_behaviors.get_time_in_utc(0)},
               'cooldown': 0, 'type': 'schedule', 'name': multi_at_style{0}.format(policy_index), 'change': policy_index}
at_style_policies.append(policy)
```
Please note the `at_style_policies`. I feel that name is more clear.
