Hi everyone I am new to angular. I am trying to create mat-cards for each object in an array however no cards appear.

Html:

I want to output some sentences when the user presses the wrong button and then exit using tkinter module (like says "idiot" or something) when they answer a question wrong and exit the process. However, command=lambda: only support only one action and the python interpreter will output an error when I add multiple lines. Is there any way to perform two or more actions for the windows made by tkinter?
This is part of the codes and I want the codes to output the self.correspondingBehavior part and then exit.

Assume that I have a molecule as below.

I'm trying to make a quiz with JavaScript and html. The user is asked to enter an answer of a question in a prompt field, the users answer and the right answer is sent to a function that compares them. If the answer subtracted with the right answer equals zero, the function will return a Point. If that isn't true the function won't return a point. If the answer from the user is anything other than 1-3 the function alerts of an invalid input. Everything here works however I want to add a feature that makes the code ask the same question again if the users answer is invalid, in other Words not 1-3. I've tried using while loops but can't get that to work. Any suggestions to how I could solve this and/or any other tips to make the code more structured.

I accidentaly named one of the fields "type" with django. Is there a way to rename it or can I still use the filter for that 'type' I understand that 'type' is a built-in function and it tries to use it and gives me errors.

I got the following code for a project:

I'm learning Angular and trying to grasp the concepts. I'm having difficulty doing something that should be simple.

I want to connect a Material Table to a service that downloads some data.

I created my service that downloads some simple data from a website. I created the Data Table using the command line. Now I must change the data source for my service.

Here is the generated file rank-table-datasource.ts:

I made a quiz using PHP arrays. It's nice because you don't have to edit HTML files all the time. You can just update your array and have a new quiz ready quickly. After a big struggle, I finally found a way to count points, it's almost done. I just want to highlight correct answers green and wrong answers red. And after submitting the form all questions and options should be printed but only correct should be green and wrong should be red. I am almost there, just don't know how to target elements of the array well. Could you help me? Please have a look. This is the array of questions:
