DiME | Resource disaggregation is a new design paradigm

Let's say I have three types of coins -- a penny (0.01), a nickel (0.05), and a dime (0.10) and I want to find the number of ways to make change of a certain amount. For example to change 27 cents:

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:

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?

Code

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:

I have an endpoint that verifies that email addresses are deliverable call it https://testService.com/verify. This endpoint comes with an api key, lets call it 'AbCd' if you concatenate both of those things and an email address in a query string and perform a get request, it gives tells you if the email address is deliverable. I am using this to validate a form and only submit if the email address is deliverable. The page where this is being used is an e-commerce landing page were no login is required so using google O-auth is not a possibility.

The problem becomes I cannot hardcode the api key "AbCd" in the front end because it is then insecure and theoretically someone could rip the api key and use the service on their own forms on our dime.

Conventional wisdom says I should execute this call on the back end and then forward the response to the app however if I make a call from the back end the front end still has to call the back end, you can find where it is making the call from the network tab and then use it in other apps.

You could secure the back end with a api key however this just brings you full circle to where we started. With an endpoint and an api key.

I'm having trouble figuring out where to place variables related to each coin and how to properly declare them.
IE: Pennies = 1, Quarters = 25.

I need to make minimum changes to the existing code, but need to figure out how to make it work.

I need your help to understand what I'm doing wrong in my for loop.

I'm trying to write a function that takes in a total amount of a bill and the total cash given to pay that bill. Return a new object that describes the total amount of change for the cashier to give back. Omit any types of change that I shouldn't give back, i.e. if I don't give back a twenty-dollar bill, I don't include it in the results.

I do get the object with results but not the way the split among dollar values expected.

I expect to get this result:
