python - 将Python字典键对转换为字符串

Question

我是Python新手，我有一个Python字典，如下所示

{"details":[{"name":"akhil","account":"ABCD"},{"name":"rahul","account":"GCOD"},{"name":"rakesh","account":"ABCD"}]}

需要将此字典转换为Python字符串，如下所示。还有一点，这本词典是动态的，所以它应该有点通用。

ABCD -
akhil
rakesh
GCOD -
rahul

提前致谢，如有任何帮助，我们将不胜感激。

Answer 1

使用简单的迭代。

data = {"details":[{"name":"akhil","account":"ABCD"},{"name":"rahul","account":"GCOD"},{"name":"rakesh","account":"ABCD"}]}

result = {}
#Group name by account!. 
for i in data["details"]:
    result.setdefault(i["account"], []).append(i["name"])

for k, v in result.items():
    print("{} -\n{}".format(k, "\n".join(v)))

输出:

ABCD -
akhil
rakesh
GCOD -
rahul
