存储在转换为字典的变量中的列表

Question

我正在使用以下命令对windows终结点执行WMI查询，该查询将返回列表中的结果。我现在想把那张单子改成字典关键：值so我可以搜索以“Name”作为名称的所有密钥，它将返回：“ASPNET”“Guest”“Admin”。在

import wmi_client_wrapper as wmi

wmic = wmi.WmiClientWrapper(
username="corp.testdomain.com/Administrator",
password="fakepassword",
host="192.168.1.100",
)

output = wmic.query("Select * from Win32_UserAccount Where LocalAccount = True")


{'Status': 'OK', 'Domain': 'localhost', 'Description': 'Account used for running the ASP.NET worker process (aspnet_wp.exe                      )', 'InstallDate': None, 'Caption': 'localhost\\ASPNET', 'Disabled': False, 'PasswordChangeable': False, 'Lockout': False,                       'AccountType': '512', 'SID': '45474748484848-1002', 'LocalAccount': True, 'FullName': 'ASP.NET Ma                      chine Account', 'SIDType': '1', 'PasswordRequired': False, 'PasswordExpires': False, 'Name': 'ASPNET'}

Answer 1

你能做到的

>>> dict1 = {'Status': 'OK', 'Domain': 'localhost', 'Description': 'Account used for running the ASP.NET worker process (aspnet_wp.exe                      )', 'InstallDate': None, 'Caption': 'localhost\\ASPNET', 'Disabled': False, 'PasswordChangeable': False, 'Lockout': False,                       'AccountType': '512', 'SID': '45474748484848-1002', 'LocalAccount': True, 'FullName': 'ASP.NET Ma                      chine Account', 'SIDType': '1', 'PasswordRequired': False, 'PasswordExpires': False, 'Name': 'ASPNET'}
>>> print dict1['Name']
ASPNET

Answer 2

如果output的结构是：

[{'Status': 'OK', 'Domain': 'localhost', 'Description': 'Account used for running the ASP.NET worker process (aspnet_wp.exe                      )', ...,  'Name': 'ASPNET'},
 {'Status': 'Degraded', 'Domain': 'localhost', 'Description': 'Built-in account for guest access to the computer/domain', ..., 'Name': 'Guest'},
 {'Status': 'OK', 'Domain': 'localhost', 'Description': 'Built-in account for administering the computer/domain',  ..., 'Name': 'Admin'}]

我会将它迭代到一个列表字典中，由字典中的键进行键控：

^{pr2}$

这也可以通过两个列表理解和dict内置函数在一行中完成：

new_dict = dict([(key, [old_dict[key] for old_dict in output])
                 for key in output[0]])

如果你有字典理解能力，你可以使用其中一种：

new_dict = {key: [old_dict[key] for old_dict in output]
            for key in output[0]}

其中的每一个都将给出一个字典，其键控方式与output中的每个结果字典都相同。output中字典中的所有值都存在于其原始字典中的键的列表中。它们是按它们在output中出现的顺序排列的。在

 'Domain': ['localhost', 'localhost', 'localhost'],
 'Description': ['Account used for running the ASP.NET worker process (aspnet_wp.exe)', 
                 'Built-in account for guest access to the computer/domain',
                 'Built-in account for administering the computer/domain'],
