I'm trying to randomize items(cards that contain english words) from an flashCards array, so that each card can randomly appear when the user reload the page. I have used Math.floor(Math.random()) function but it doesn't work. How can I get randomly cards from an array of cards?

The goal of my code is to simulate a very primitive bank by reading banking actions from a text file. I successfully made the program using lists to store the information, but then figured I could redo it using nested dictionaries to remove the need for iteration through the lists.

I'm facing a problem since last week with my tsv that I would like to modify and transform into a pandas dataframe.

My file looks like this :

I am trying to run an application I found on github, this one: https://github.com/CSIRT-MU/AIDA-Framework

I am running it in a Ubuntu 18.04.1 virtual machine. At some point in its data processing pipeline it uses spark and it seems to get stuck at this point. I can see from the web UI that some data that I send there is received as a batch. However, it seems to never finish processing the first batch (even though it has 0 records in it). Unfortunately I am not experienced with spark and don't know what exactly is failing. When searching for a fix I came across suggestions that there might not be enough cores for all executors. I tried to increase the cores to 3, but this did not help.

I have provided all the screens from the web UI, I hope that they show the issue clear enough. Does anyone know what I am doing wrong here?

The outputs of the queued and incomplete batch processing jobs are

The goal is filter out a search result so that the result shows a certain value and filtering out other undesirable values. I'm thinking of a combination between IN and NOT IN? Basically, in the provided example here, the goal is to retrieve the courses that Lennart has taught but not Alan or Kjell.

How does one select a certain column whose got values of same value in another column? In this case, the aim is to select the names of the people who teach in the same class. So how does one select the names of the peple who teach in the same class?

I'd like to know how to find the names (namn) of the people who have taught on a course (kkod) but have never been course coordinator (kansv). Is it a minus operation (not exists operation)? The result should look like:

Basically I want to select the rums that appear more than once but with its teachers (namn) having different telephone values (tel) ( thatd be rooms altair, kompis, and mulitplan). How do I select the rows so that it becomes;

I have this student db with four columns: first_name, middle_name, last_name, school, birth_year. I have successfully read the content of the db using SELECT statement, but here's where I got stuck at:

How do I print the query result with the format like this: first_name middle_name(if available) last_name was born in birth_year? So for every row in the query the intended result should do this: Aida Blue was born in 1985.

For now if I run print(all_rows) the code will print the query result like this: [{'first_name':'Aida', 'middle_name': None, 'last_name': 'Blue', 'school': 'Washington', 'birth_year': 1981}, {...}, ....]

Below is my code attempt at such problem:
