QUESTION
Community of Stackoverflow:
I'm trying to create a list of sublists with a loop based on a random sampling of values of another list; and each sublist has the restriction of not having a duplicate or a value that has already been added to a prior sublist.
Let's say (example) I have a main list:
...ANSWER
Answered 2022-Mar-19 at 00:09I realize you may be more interested in finding out why your particular approach isn't working. However, if I've understood your desired behavior, I may be able to offer an alternative solution. After posting my answer, I will take a look at your attempt.
random.sample
lets you sample k
number of items from a population
(collection, list, whatever.) If there are no repeated elements in the collection, then you're guaranteed to have no repeats in your random sample:

I have some problems with a project. I want to display some data, that I retreive from an API, in a dropdown menu. I used the .map() function and jsx to display everything, but nothing is working, the dropdown menu stay empty whereas a console.log(cities) show me that my array is filled.
...ANSWER
Answered 2022-Feb-04 at 21:15Your city array is always empty because you are not waiting for the API to send the response back. To achieve this you can use Promises

QUESTION
I have a Docker container (Linux container running on Windows with VLS 2) running a .NET Core 5.0 application, whose Dockerfile
and docker-compose.yml
were created by someone else. I spun it up with docker run
and passing a single environment variable and port mapping. It works just fine until it attempts to create a file, which it attempts to do with a statement like this: System.IO.File.WriteAllText($"/output_json/myfile.json", jsonString);
, and errors out. The error message says
ANSWER
Answered 2021-Aug-31 at 15:55The path /output_json
probably doesn't exist in the docker image. That could be because you're meant to map a directory on your host to that path. Then the container can put it's output there and you can grab it after the container is done.
To try it, you can make an empty directory and map that to the /output_json
path in your container by running the following 2 commands from a command line
QUESTION
Hoping someone can help me on this. I've created my own Keycloak Realm, and client. I am using Spring boot and KeycloakRestTemplate from org.keycloak.adapters.springsecurity.client.KeycloakRestTemplate; to make all my calls.
I've been successful in adding client-level roles to the user role mapping to any given user.
I prefix my URI with /admin/realms/ when using the Keycloak API docs. So far all my requests have worked (getting a list of users from my client, getting a list of users that have a particular client-level role, and even adding client-level roles to a user as described above)
My problem is I cannot delete client-level roles from a user. I've looked at the keycloak docs and it looks like I've followed everything correctly. I also made sure the user had applicable client roles available to be deleted. I really appreciate any comments or help given!!
https://www.keycloak.org/docs-api/14.0/rest-api/index.html
"Delete client-level roles from user role mapping DELETE /{realm}/users/{id}/role-mappings/clients/{client}"
...ANSWER
Answered 2021-Jun-22 at 23:38KeycloakRestTemplate
appears to inherit all of its methods directly from Spring’s RestTemplate
. According to the documentation for that class, the second argument to delete
isn’t a request body, as I think you’re intending. Rather, it’s a vararg of objects used to expand template variables in the URI.
There doesn’t appear to be a variant of the delete
method that allows you to supply a body, so you’ll probably need to use one of the variants of the execute
or exchange
methods that accepts an HTTP method and a request entity instead. In fact, the RestTemplate
API makes this quite difficult to do, because it’s generally assumed that DELETE
requests don’t have bodies.
QUESTION
I am trying to take a list of dictionaries, which is the return from a job's board API, and insert that data into a SQL table for one of my teammates to access. The issue that I am running into is that when I run my script to read through the dictionaries one at a time and insert them into the MySQLDb Table I get through some number of runs before I hit an error about not enough arguments for the format string. This doesn't make much sense to me, both due to my lack of experience but also, because I set up the number of arguments based on len(dict). Any ideas where I got off track?

This is the method written in python:
...ANSWER
Answered 2021-Feb-16 at 10:25Will combining the two halves take linear O(n) time just like in merge-sort or constant O(1) time? I tend to think that since it's only an addition constant O(1) time is more suitable.
You are correct.
So if we assume one call does 1 unit of work (ignoring the recursive calls), all we have to do is establish the number of calls. If we assume that n = 2k we end up with 1 + 2 + 4 + ... + 2k = 2n - 1 calls. Which is just O(n).

This is probably going to be a long question so apologies in advance.
Here's my situation, I'm hoping you guys can put me on the right track:
Senario: I have 2 main files, let's call them app-prod.py and app-dev.py. Both (programs?) files use Selenium to scrape websites, 1 is the main site (work) and the other is the dev site (local). app-prod.py needs some login code (username, password and auth code) and it has to tell Selenium to click on certain buttons that are only on the production site.
app-dev.py doesn't need the authentication or the instructions to navigate because the sites are not the same. The dev site is just some html tables that mimic the prod site but without all the login stuff.
