```

I have the two lists with dicts above, how can I append the first to the second such that:

```
[{'ContainerID': '9bcb46615a',
  'MemUsage': 2.85546875,
  'MaxMem': 1.9522056579589844,
  'Size': 0.0},
 {'ContainerID': '9aadddf8e0',
  'MemUsage': 17.203125,
  'MaxMem': 1.9522056579589844,
  'Size': 19.391637}]

```
