Python对json排序分组

res_dl是一个json字符串，如下：

以ip为关键字进行分组排序：

#先对返回结果按IP排序，然后再使用groupby分组计算ip访问数量
sorted_res_dl = sorted(res_dl, key = lambda x:x["ip"])

ret = list()
for _, group in groupby(sorted_res_dl, lambda x: x.get('ip')):
    ret.append(list(group))
print(ret) #分组完成

for item in ret:
    print('%s，扫描 %d 次'% (item[0]['ip'],len(item)))
