sorry for my poor English. I' am new in python. I have the code below that seem not working. I cannot figure out why :

I am trying to write a Python code to basically do a sumproduct function based on the item selected and the quantity of that item selected.

My code is below. I am having trouble referencing the combobox values. The calculate function is where I'm going wrong. How do I reference the comboboxes I have inputted onto the 'NewWindow'? I add comboboxes to the page based on the number of items selected and the all have the same values,etc.

For example if I select 2 'pizzas' and 1 'CocaCola' then the code should print 33. ((2*$15)+(1*$3))

This is my error:

File "C:\Users\aaaaa\Documents\pizzamenu.py", line 41, in calculate cost = fooditems[x] KeyError: 0

>

I am trying to print the values of the checkboxes I select. Can someone help point me in the right direction? I am getting an error on this line - print(my_items[item])

This is the error:

TypeError: list indices must be integers or slices, not IntVar

I would like to have my character add items to their inventory from a dictionary, however when I add them it only gives me the 'value' return, not the 'key' as well. I would like to use both for different parts of the game "You are holding 'key', it does 'value' damage" for example.

I think I understand this is adding the dictionaries 'value' because my inventory type is a 'list', but having trouble finding a simple way to add the dictionary items.

Thanks in advance for the help!

I have a huge dictionary called Menu. Here's a snippet of it:

My questions is what is the best method I could use to decode a JSON that has many different keys? Right now, I am creating a var for every single one. This seems inefficient/hard coding, and I have about 8 different menus like this to decode.

Here is my JSON: (long, I know)

Just some background information so you don't get confused. I am trying to build a restaurant website with dropdown menus. It is NOT DONE so there might be some more errors. Anyway, only one link is done if you run this code. If I click the link it is supposed to return the array onto the console. Here is my code, please tell me if there is something wrong!

Given a template that looks like this:

What I am trying to do is repeat a line item and the user will be able to change the quantity of each item on the line. for example

• Soda ............ - 1 +
• Breadsticks .. - 0 +
• etc... ............. - 3 +

so far I have been able to change value and log that the change is happening, but the value that is displayed does not change.

below is what I have so far
