字典列表怎样合并字典中不同的值

[ns2250225]

有个字典列表是这样：
l = [
{"name": "mqx", "url": "www.google.com"},
{"name": "mqx", "url": "www.baidu.com"},
{"name": "other", "url": "www.baidu.com"},
]
希望的输出是：
output = [
{"name": "mqx", "url": ["www.google.com", "www.baidu.com"]},
{"name": "other", "url": "www.baidu.com"},
]

请问有什么好的方法吗，希望大神不令赐教

遍历后放入字 list 而不是字符串

[fml87]

```
from collections import defaultdict
d = defaultdict(list)
for i in l:
d[i['name']].append(i['url'])
output = [{"name": i[0], "url": i[1]} for i in d.items()]
```

@fml87 感谢大神！

pandas groupby

如果仅仅是输出，就没必要用 pandas
不过如果像这种二维变三维，还有后续计算，可以试试 pandas

[codingcrush]

from itertools import groupby
print([{k: [item["url"] for item in v]} for k, v in groupby(l, key=lambda item: item["name"])])
