我试图将列表转换为元组，将自定义列表转换为字典。我试图划分包所有者、提交者和消费者

Question

我正在尝试将列表转换为元组，将自定义列表转换为字典。我试图划分包所有者、提交者和消费者。请检查以下预期输出。

lst = [('name1', 'email1','id1','new1',11,'1','po'),
       ('name2', 'email2','id2','new2',12,'2','sub'),
       ('name3', 'email3','id3','new3',13,'3','sub'),
       ('name4', 'email4','id4','new4',14,'4','po'),
       ('name5', 'email5','id5','new5',15,'5','cons')]

我试过使用下面的代码但无法获得预期的输出

def lst_of_dict()
    res = [{"name":each[0], "email":each[1], "psid":each[2} for each in lst]

return jsonify({"add_sub":res})

我正在尝试低于输出

{
"add_sub":{
"sub":[{"id":"id2","name":"name2","email":"email2"},{"id":"id3","name":"name3","email":"email3"}],
"po":[{"id":"id1","name":"name1","email":"email1"},{"id":"id4","name":"name4","email":"email4"}],
"consumer":[{"id":"id5","name":"name5","email":"email5"}]},}

我是新手 python 请建议我更改逻辑

Answer 1

collections.defaultdict 救援：

from collections import defaultdict

lst = [('name1', 'email1', 'psid1', 'new1', 11, '1', 'pack owner'),
       ('name2', 'email2', 'psid2', 'new2', 12, '2', 'submitter'),
       ('name3', 'email3', 'psid3', 'new3', 13, '3', 'submitter'),
       ('name4', 'email4', 'psid4', 'new4', 14, '4', 'pack owner'),
       ('name5', 'email5', 'psid5', 'new5', 15, '5', 'consumer')]

by_role = defaultdict(list)

for name, email, psid, new, id1, id2, role_name in lst:
    by_role[role_name].append({"name": name, "email": email, "psid": psid})

print({"add_sub": dict(by_role)})

打印出来

{'add_sub': 
  {'pack owner': [{'name': 'name1', 'email': 'email1', 'psid': 'psid1'}, {'name': 'name4', 'email': 'email4', 'psid': 'psid4'}],
   'submitter': [{'name': 'name2', 'email': 'email2', 'psid': 'psid2'}, {'name': 'name3', 'email': 'email3', 'psid': 'psid3'}],
   'consumer': [{'name': 'name5', 'email': 'email5', 'psid': 'psid5'}]
  }
}

Answer 2

试试这个，

res = {"add_sub":{}}
for name, mail, psid, *_, role_name in lst:
    res['add_sub'].setdefault(role_name, []).append({"name":name, "email":mail, "psid":psid})

输出：

{'add_sub': 
  {'consumer': [{'email': 'email5', 'name': 'name5', 'psid': 'psid5'}],
  'pack owner': [{'email': 'email1', 'name': 'name1', 'psid': 'psid1'},
                 {'email': 'email4', 'name': 'name4', 'psid': 'psid4'}],
  'submitter': [{'email': 'email2', 'name': 'name2', 'psid': 'psid2'},
                {'email': 'email3', 'name': 'name3', 'psid': 'psid3'}]}}
