问题 I have a csv file with data as below XPATH,ColumName,CSV_File_Name,ParentKey /integration-outbound:IntegrationEntity/integrationEntityDetails/supplier/forms/form[]/id,id,integrationEntityDetailsForms.csv, /integration-outbound:IntegrationEntity/integrationEntityHeader/attachments/attachment[]/id,aid,integrationEntityDetailsForms.csv, /integration-outbound:IntegrationEntity/integrationEntityDetails/supplier/forms/form[]/records/record[]/Internalid,Internalid,integrationEntityDetailsForms.csv,

问题 I am using a dictionary wrapper class, and I want to iterate through it using key-value pairs as seen below private void LoadVariables(LogDictionary dic) { foreach (var entry in dic) { _context.Variables[entry.Key] = entry.Value; } } but a NotImplementedException is thrown because I did not implement the GetEnumerator() method. Here is my wrapper class: public class LogDictionary: IDictionary<String, object> { DynamicTableEntity _dte; public LogDictionary(DynamicTableEntity dte) { _dte = dte;

问题 Is there a way to share a huge dictionary to multiprocessing Subprocesses on windows without duplicating the whole memory? I only need it read-only within the sub-processes, if that helps. My programm roughly looks like this: def workerFunc(args): id, data_mp, some_more_args = args # Do some logic # Parse some files on the disk # and access some random keys from data_mp which are only known after parsing those files on disk ... some_keys = [some_random_ids...] # Do something with do_something

问题 I have a list of objects with this definition: type MyObject struct { ID int `json:"id"` Level int `json:"level"` CityID int `json:"city_id"` } I want to categorize them based on CityID in order to get a list of lists where each inner list's items have the same CityID . For example, if I have the following list: [ MyObject {ID: 1, Level: 12, CityID: 7}, MyObject {ID: 2, Level: 15, CityID: 2}, MyObject {ID: 3, Level: 55, CityID: 4}, MyObject {ID: 4, Level: 88, CityID: 7}, MyObject {ID: 5,

问题 I'm trying to find a way to look into a Map array value to see if it exists if it does return the Map key as a variable. this has stumped me for a bit now as I don't do much javascript. const map = new Map([ ["KEY1", ["dummy1","dummy2","dummy3"]], ["KEY2", ["dummy4","dummy5","dummy6","dummy7"]], ["KEY3", ["dummy8","dummy9"]], ]); so say I have dummy4 as a var I want to look in map and see it there in the array of values with key2 and return the key into a new variable of sting "KEY2" 回答1: I'm

问题 I have list of dictionaries. I need to sort it. If there is no nested dictionaries in those ones, it goes well. But i need to sort nested dictionaries. lis = [{"name": "Nandini", "age": {"name": "Nandini", "age": 20}}, {"name": "Manjeet", "age": 21}, {"name": "Nikhil", "age": 19}] # using sorted and lambda to print list sorted # by age print("The list printed sorting by age: ") print(sorted(lis, key=lambda i: i['age'])) So, i have the error: Traceback (most recent call last): File "D:\json

问题 In other words given the list of dictionaries how could I efficiently end up with a list of interfaces which have multiple mac addresses tied to them? In the example below we would output Te1/1/1 since there are three mac addresses tied to this interface, it's possible the result could contain multiple interfaces. Blank values for interface key should not be counted. The input list could be long, so I'm wondering what is the fastest way to approach this problem? { "mac_address_table": [ {

问题 I'm trying to use Ansible to loop through a nested dict and add a new key:value. I'm able to add a value using combine to the top-level dict but unsure how to update the value dict. I see that loop can be used to iterate through the dict but how can update be done at the same time? My Dict {'host-a': {'os': 'Linux', 'port': '22', 'status': 'Running'}, 'host-b': {'os': 'Linux', 'port': '22', 'status': 'Running'}, 'host-c': {'os': 'Linux', 'port': '22', 'status': 'Running'}} I'm able to append
