QUESTION
I am trying to create a GUI in Python for a class assignment called 'Chocolate Vending Machine'. Students are required to use Python's Tkinter. We list a couple of chocolate brands such as Snickers, Twix and Mars and put a price tag on each of them. The user goes through these steps:
- Input a float value of how much money he has (can be any value)
- He selects how many of each chocolate he wants
- That value is printed to the console under: "Total Cost"
- The original balance (how much money he originally had) minus Total Cost prints the new balance
Please refer to the code below. How can I abstract the following lines of code so that it still works, but limits the number of lines? Note that I am not pasting the whole code of the application as it is just too many lines of code. So here's a snippet to narrow things down:

QUESTION
Right here, I am trying to create a GUI calculator in Python for a class assignment called 'Chocolate Vending Machine'. Basically, students are assigned to create a GUI using Python's Tkinter. We list a couple of chocolate brands such as Snickers, Twix and Mars and put a price tag on each of them. The user goes through these steps:
- Input a float value of how much money he has (can be any value)
- He selects how many of each chocolate he wants
- That value is printed to the console under: "Total Cost"
- The original balance (how much money he originally had) minus Total Cost prints the new balance
Please refer to the code below, and perhaps copy and paste it into your Python application:
Let me try to explain what the problem is. If you look from line 42 to 55, you will see my function "Total()", which, in theory, adds up all of the quantities and prices of chocolate that the user would like. The code that says: "Total.set(CostOfMeal)" should print out the total cost on the right hand middle box next to "Total Cost".
But it doesn't. When I try to press the "Total" button, it doesn't work. instead, Python gives me this message:
Exception in Tkinter callback Traceback (most recent call last): File "/Library/Frameworks/Python.framework/Versions/3.5/lib/python3.5/tkinter/init.py", line 1550, in call return self.func(*args) File "/Users/s190528/PycharmProjects/CSP/GUI Testing 2.py", line 55, in Total Total.set(CostOfMeal) AttributeError: 'function' object has no attribute 'set'
Could somebody possibly help me with this, or better yet, provide code that would add up all the values and print it? Thanks.

Answered 2018-Feb-27 at 13:54You've defined Total
as a function (def Total():
) and then appear to be trying to use it as some object that has a set
method. That's why you're getting the AttributeError.
