QUESTION
I have to write a python program for the following problem
Write a complete and syntactically correct Python program to solve the following problem: Write a program for the local coffee shop owner who wants to be able to control his inventory. The program must be written in accordance with the following specs:
- Write the following data to an external file, name the file coffeeInventory.txt Description Pounds Blonde Roast 15 Medium Roast 21 Flavored Roast 10 Dark Roast 12 Costa Rica Tarrazu 18
- You do not need to write the table, just the data
- Read in the records you just wrote to coffeeInventory.txt and display them on the screen and sum the total pounds of coffee
- Append these records to the file Guatemala Antigua 22 House Blend 25 Decaf House Blend 16
- Modify the file by allowing the owner to remove data from the file: a. Ask the owner to enter a description to remove b. If the description exists, remove the coffee name and the quantityc. If the description is not found, display the message: That item was not found in the file.
- Modify the file by allowing the owner to delete data from the file: a. Ask the owner to enter a description to delete b. If the description exists, delete the coffee name and the quantity c. Replace the name and quantity of the coffee removed in step b by asking the user to enter a new coffee name and quantity d. If the description is not found, display the message: That item was not found in the file.
this is what I have so far

QUESTION
I have written code which allows a user to click on a div to open a dropdown menu of radio buttons. I am trying to get the arrows to rotate 180* once the dropdown menus open, and to rotate back 180* when dropdown menu closes. I wrote a couple lines of code inside the current code block. I believe to be close to solving it. Any tips are greatly appreciated. Thank you! Will upload html, css, and js.

drinks = ["espresso", "chai", "decaf", "drip"]
caffeine = [64, 40, 0, 120]
zipped_drinks = zip(drinks, caffeine)
#Uncomment below
#print('list here:', list(zipped_drinks))
drinks_to_caffeine = {key:value for key, value in zipped_drinks}
print('dictionary here:', drinks_to_caffeine)
ANSWER
Answered 2021-Jun-01 at 12:58Coming from documentation for zip
Make an iterator that aggregates elements from each of the iterables. Returns an iterator of tuples, where the i-th tuple contains the i-th element from each of the argument sequences or iterables.
Yes that is completely normal because zip returns an iterator and iterators are evaluated only once, so when you uncomment your print statement, the iterator is evaluated at that time, and later when you try to form dictionary out of the zip object, the iterator has nothing at all, all the values are already yielded by that time.
The code snippet from documentation:

QUESTION
Assignment Instructions:
Develop a simple shopping cart application that uses session objects to store the information. You will have to create an ASP.NET project that contains two web forms. The first web form, ShoppingCart.aspx, allows the user to select items using a set of checkboxes. This page shows also the number of items in the cart.
The second web form, Display.aspx, displays the number of selected items in a table and allows the user to go back to the first web form and continue shopping.
- I am using a CheckBoxList to list my products, and I built a table with IDs in the cells to receive the data the user checks off.
- (I considered the idea of using CheckBox vs. CheckBoxList, but this would not be the appropriate solution and doesn't easily allow counting total items selected)
- I have tried using cookies and session state variables, but I can't figure out how to associate them to the table.
- I can transfer test data from labels and textboxes, anything with an ID, but not my CheckBoxList items.
How do I reference which checkboxes are selected on page 1, that will update the desired table cells on page 2, after clicking the 'checkout' button without unique IDs on the list items?
Example: If... 1lb Dark Roast is selected on page 1 ... (identified as 'p001' for product 1 on next page)
...ANSWER
Answered 2021-Feb-22 at 01:48Ok, so the problem we have here is of course matching up the “thing” you selected on one page, and then figuring this out on the next web page.
To be fair, the problem here is that no doubt you have to "make up" the data here. And that REALLY hurts this whole process, since you having to type in the data two times (once on this page, and then on the target page). Worse, you have to match up by "text". One little space, period etc. and your whole system will fall down.
I going to suggest we NOT worry and NOT have to match up the values. We can in one shot get rid of a HUGE problem, and ALSO reduce the markup, the code and all your life hassles (well, ok, just the coding part - can't fix everything!!!).
So, I going to suggest that in place of the check box "list", we create a table and use that for BOTH pages. This will then not only keep us out of rooms with padded walls, but we can deal with a "row" of something that you select, and just not give one hoot as to the spelling or even what we place in that row. And by doing this, you could with almost no code changes change the "list" from our table to a database - and the whole she-bang would work!!
So, lets use (create) a table, and not only is this easy, but I think far more clean to setup our data.
So, we will have this at the start of the page (a table and some total values for the WHOLE page class.
QUESTION
I've been trying to use something to ping my heroku app to keep it awake. I first tried using https://kaffeine.herokuapp.com/ but quickly found it to be unreliable and my app would still periodically shut down. Now I'm using https://cron-job.org/ and it is wonderful. I tried cancelling kaffeine from running, but it doesn't seem to be working. I go to the website and click "remove your app?" I see that the url gets #decaf put at the end, but when I put my website in the box and click the button it just says "App already added". Does anyone have any idea how to stop it from pinging my website?
...ANSWER
Answered 2020-Jul-30 at 05:21if you click "remove your app" so that the #decaf is in the URL and then refresh the page a new window pops up where you can remove your app.
