其实还可以一行搞定：
{k: [j for i in v for j in i.keys()] for k, v in mylist.items()}
{k: [j for i in v for j in i.keys()] for k, v in mylist.items()}

```
mylist = {"key": [{'a': '1'}, {'b': '2'}]}
all = {}
for k, v in mylist.items():
all[k] = []
for j in v:
all[k] += j.keys()
```
mylist = {"key": [{'a': '1'}, {'b': '2'}]}
all = {}
for k, v in mylist.items():
all[k] = []
for j in v:
all[k] += j.keys()
```
