nickel | Better configuration for less

I am trying to build a Tkinter GUI for my code that returns the least amount of coins needed given an amount. I used a lambda function for my code because I know you can't pass arguments with Tkinter.

I apologize in advance for the long code guys. I spent hours on it and couldn't find out what to do to fix it. I appreciate any help or advice you can give me.

Here is the error Im getting and then there is my code:

Im a student and this is my first experience with Python so I'm having a little trouble. The electronic workbook I'm using, Zybooks is doing a horrible job of explaining (or lack thereof) how to go about doing what it's asking. The entire lesson does not once talk about how to write this specific type of code.

It asks...

Write a statement that assigns total_coins with the sum of nickel_count and dime_count. Sample output for 100 nickels and 200 dimes is:

I have a site that lets people answer coding problems. I want to save the questions that I ask them in a mongodb database, and the answers they send in as well. In testing the routes I have set up in my express application, I cannot figure out how to send this formatted text in the request to successfully save it to the database. I would like to keep this format as I use a few npm packages on my react front end to parse this data to make code snippets.

Here is my mongoose model:

I would like to work with the European Transparancy Register with Python, however, I had some troubles so far. Below you will find a very simplified version of the XML (which normally contains 1.6 million lines).

I would like to retrieve all the companies that have ticked the category Digital economy and society in their interests.

However, I am having great difficulty using the findall() of ElementTree with this very particular XML structure. You can find below an excerpt of my code with the first results I was able to obtain. The filter returns nothing.

Just a newbie learning Rust here.

When you have multiple loops like in this example. Is there an easy/idiomatic rust way to combine them all into a single loop? or perhaps just a smarter way to do this?

I have a text, where I need to remove the product IDs where the expected result must be as show below. How do I remove it using the js replace function

I am in a beginner scripting class where we need to write some code that makes change based on integer input. It also needs to print the correct plurality for each coin type. I am having some trouble getting my code to work, as it stops at the first operation it performs and I'm not sure how to get it to continue. I'm guessing it has something to do with how I've laid out all these elif statements and I'm not sure what the proper thing to do is to get the code to continue if it still has a remainder for the change:

Hello I have had some trouble with my projecting I'm trying to make someting where you can search a value and it returns an the row that value was in. I've only been able to do it with the atomic number because they're ordered. I was planning to use classes but I don't think I'll actually need it (that's what import element is for)

Here's my code:

I am currently learning programming in Swift from a course I bought on Udemy.

One of the things I am doing now is to build a quiz app. As a final challenge on the quiz app, I am converting the app to be a multiple choice quiz instead of just true or false.

Note: At this stage I have just learned about the MVC design pattern, and the challenge requires to keep it in this way.

So I have mapped out what I need to do, but I am running into a problem where I get the error "Type 'Question' has no member 'Subscript'.

I tried to search for this on Stackoverflow, but I haven't been able to figure out why this affects my code.

So this is my QuizBrain.
