Trying to save values from tkInter scale

This is my first post so please have patience
I've got a school assignment to create an art supplies application and I've drawn a blank why my tkinter scale values are not saving to a file.
The customer details and submit button code works as expected (saves to a file = info.txt)
The Order tab page doesn't work as expected = does not append info.txt with specific quantities of art supplies ordered
Here's my code

I've also tried to get the customer details submit button to save to the file and then close down the customer details tab or ar least move the focus to the 'View all products' tab (so that the user can then concentrate on their order).
Help!

It looks like your problem is one of variable names. You are clobbering the scale object with the result of a call to get(), but then you write to what I assume was the variable you intended to assign. That variable is never initialized and is therefore None, so nothing is written to the file.
e.g.
Paint = Paint.get()
...
Paint = Paint.ljust(150)
...
fileObject.write(... + paint + ...)
should be
paint = Paint.get()
...
paint = Paint.ljust(150)
...
fileObject.write(... + paint)

How to deselect a radio button tkinter

I have looked at several online tutorials, none of them seem to work properly, I need to have the radio button deselected once the clear button is clicked. The .deselect() method does nothing. Clearing the text and entry boxes is working properly. Please assist.

You are trying to deselect the StringVar. You need to set it to something that isn't an option, in other words a value that none of the Radiobuttons use in the value argument:
self.SrcDstport.set(None)

Using StringVar data as a list

I've been following this website for a while. It is really helpful. So, thanks for all the useful tips.
I've been searching for this answer for the past two weeks without any success, so now I'm compelled to ask out of total frustration with my current obstacle.
How do you use StringVar as a list?
Basically, I was coding the following program for my wife. The code is pretty messy as it is my first program I've tried to code.
The idea was that I would take 3 variables; password, secret number and website and then do some work on them using if statements and lists to create a unique password.
First problem was that I couldn't restrict the character length of the entry widgets but in the end i solved that but i still want to limit the characters that can be input.
for instance in the website entry box, i want to allow only letters.
If I could convert StringVar to a list, I could do some work with messy if statements to allow only certain characters in each index but everythime i try it says that stringvars cant be used as a list.
I need them as a list to limit the type of characters that can be entered and also so that i can do work on the variables to get the final output.

# add functionality, fix validation

To restrict the type/number of characters that can be typed into an entry widget, you can use the entry validatecommand. Here is an example to allow only letters and another one to restrict the entry to 4 digits:
from tkinter import Tk, Entry, Label
def only_letters(action, char):
if action == "1":
# a character is inserted (deletion is 0) allow the insertion
# only if the inserted character char is a letter
return char.isalpha()
else:
# allow deletion
return True
def only_numbers_max_4(action, new_text):
if action == "1":
return new_text.isdigit() and len(new_text) <= 4
else:
return True
root = Tk()
# register validate commands
validate_letter = root.register(only_letters)
validate_nb = root.register(only_numbers_max_4)
Label(root, text="Only letters: ").grid(row=0, column=0)
e1 = Entry(root, validate="key", validatecommand=(validate_letter, '%d', '%S'))
# %d is the action code and %S the inserted/deleted character
e1.grid(row=0, column=1)
Label(root, text="Only numbers, at most 4: ").grid(row=1, column=0)
e2 = Entry(root, validate="key", validatecommand=(validate_nb, '%d', '%P'))
# %P is the new content of the entry after the modification
e2.grid(row=1, column=1)
root.mainloop()

Calling lists when lists when lists are empty in TKinter

I wish to print from a list where the user enters an input and then has that input printed from a list. This however doesn't work without a blank string in the list as it says that the list is too short for the data to be shown in a label. I want for this to have the input printed immediately after pressing the continue button not after pressing the next button.

python gui calculator, how should i force operands to work on number variables between them?

I got this GUI calculator working with two numbers and now I want to add a third number. I got it working with addition, then multiplication.. then adding a lot of numbers and subtracting/dividing after the adds or multiplying. Now if I try to get it to be a little bit more complicated I'm getting confused, because I may have set it up wrong.
The logic is something like this:
6 * 6 - 1 (calculators on windows don't do order of operations)
But in my script,
6 is first stored as evar.
Then the multiply function is called by the * button.
The multiply function appends evar to a list called FirstNumber.
The second 6 is now stored in evar.
The divide function is called by the / button.
The logic in divide is to set evar to FirstNumber.
Now the second 6 is set in firstNumber.
However, since firstNumber is a list, the sum of the two values are 12. However, I want it to be 36.
If I now subtract 1 on the calculator,I want it to be 35, but logically it's going to be 11.
The list doesn't know what operands are pressed between numbers, can someone steer me toward a way to do this?
