I would like to connect my layout.html file with a CSS file so that every other page extending my layout.html has access to this CSS file.

That is the code:

layout.html

I want to finish my To-Do app. However, I still can't edit an item properly. My idea was to update the database by picking the particular item and overwrite its information with .save(). Could someone figure out the correct update() function to make it work?

Here is my code:

urls.py

I try to save the tasks in my ToDo app with AsyncStorage so that they can be retrieved after an app restart.

So far I have managed to save the tasks. However, an empty array is always saved in the first run. If I want to create a new task, it only saves it the second time I click the button. Logical if the whole thing runs asynchronously. I just can't figure out where my fault is. I would be very happy to receive help and tips.

Here you can see the empty array when creating the first task: Reactotron Empty Array

And here you can see the first value get's saved after i created the second task: Reactotron AsyncStorage after second click

First Part:

I'm learning Vue and set myself the task to create a to do list. To make it prettier, I wanted to style my checkboxes and used this link as a basis.

It works mostly fine: I can click on undone tasks to make them done and the other way round. However, if I click on a done task, the next done task (if there is any) gets the styling of an undone task (while correctly staying in the done department). It looks like this:

I can't figure out why this is happening. Can you? Thanks for any help!

Here is my code:

What do I want to do?

I build an App in which you can view different lectures. You are suppose to chose a lecture out of a Navigation View then click on Start Lecture and contine reading.

How is the App build up?

Page 0: MainMenuView - NavigationView that shows 5 Items (Lectures)

I just started learning web scraping with Python 3, and I am trying to apply it in a small project which consists of extracting data from job listings. I did look for answers and found some questions which touched a somewhat similar subject, but none of them seemed to have the exact same use case - at least that is my understanding. 

I extracted company URLs from the search results of a website and appended the company URLs in a list named sitelis. Then, I looped through sitelis to extract the json data from each of the company URLs. However, I have a problem to retrieve the json data from some of the company URLs (see traceback: json.decoder.JSONDecodeError: Invalid \escape) - while the large majority URLs work just fine. Any idea what could cause this? I am a bit lost since 90% of the URLs work fine, and for those few which do not parse correctly I cannot find any differences which would explain it.

Thanks a lot for your help!

Here is an example of such an error:

This is the traceback:

i have to do a order system for a fastfood restaurant (its just a school project). I have finished the tool already.

But the teacher told us to use getch instead of scanf.

But i dont understand, how to implent it.. Can i just replace my scanf in the code with getch? I dont need the Echo from Scanf and dont need confirmation with the ENTER-Key.

The task was:

Create a CMD-Tool in the Programming Language C. NO GUI! The Solution must include the commands „malloc“, „realloc“, „getch“, and free. The CMD Tool is a order process for a imaginary fast food restaurant. The menu looks like this:

A „Big Burger“ 4,90€

B „Little Burger“ 1,90€

C „Wrap“ 4,90€

D „Salat“ 2,90€

E „Frites“ 1,90€

F „Softdrink“ 1,90€

G „Watter“ 1,20€

H „Ketchup“ 0,30€

The cashier can type in the order with the keyboard.. If someone order Meal A and Meal C. He types the Letter a or A and C or c. Lower and Uppercase letters doesnt matter.

Every Order should be displayed in a single line.

After the Order is complete, the tools should show a summary of the order. All the meals that was ordered and a summary of the price. The order should be completed by pressing the letter X.

With the letter Z you can undone the order.

My Tool with Scanf:

I have the following german text with some literature references:

... Im Rahmen der psychologischen Anwendungsfächer hat sie in den letzten Jahren einen rasanten Zuwachs zu verzeichnen, sowohl hinsichtlich ihrer Forschungsindikatoren (Publikationen, Drittmitteleinwerbungen, Berufungen auf Professuren) als auch ihrer praktischen Bedeutung, insbesondere im Diskurs der Empirischen Bildungsforschung und – nicht zuletzt – der Anzahl ihrer Lehrbücher und Nachschlagewerke (Hasselhorn & Gold, 2017; Klauer & Leutner, 2012; Renkl, 2008; Rost, Sparfeldt & Buch, 2018; Seidel & Krapp, 2014; Schnotz, 2011; Wild & Möller, 2015 etc.). Warum und mit welchem Ziel also, so kann man berechtigt fragen, noch ein Lehrbuch der Pädagogischen Psychologie? Mit der Umstellung der Psychologieausbildung an den deutschen Universitäten vom Diplom- auf ein Bachelor-Master-System (BSc/MSc) ist auch für die Pädagogische Psychologie eine neue Situation entstanden. Das Rahmenmodell zur Ausgestaltung des BSc/MSc-Angebots der Deutschen Gesellschaft für Psychologie (DGPs, 20051) fasst die Pädagogische Psychologie unter die „etablierten Anwendungsfächer der Psychologie“ und sieht deren Einführung im Studienmodell schon für das 3. und 4. Fachsemester im Bachelor-Studiengang vor... Folgt man der Argumentation von Vertretern behavioristischer Lehrzieldefinitionen, dann besteht ein Lehrziel in der Bewältigung einer Menge von Aufgaben, die ihrerseits wiederum einen Gegenstandsbereich vollständig oder repräsentativ abbilden (Klauer, 1987).

The goal is to match the bold substrings while omitting the italic ones. The rule should be something like "match anything in parentheses that has at least a digit in it".

I tried it with rules like \(.*?\d+.*?\) but that matches over the first two parentheses blocks, from (Publikationen to etc.).

I'm new to web development. I'm trying to create a website with some basic tools. I'm facing a syntax problem while trying to write HTML and PHP at them same file. I want to create a dynamic select list based on my database. Here is my code:
