[Tkinter] need help using a returned value to import module

[buran]

Here is something I did from your code. Of course you can go OOP and refactor it using classes. Also you may need to adjust the GPIO part (what you said will do anyway)


vending_gui.py

from tkinter import *
import vending

def make_label(title, row):
    lbl = Label(root,text=title, bg="black", fg="#FFEFDB",font="Times 32", width=14)
    lbl.grid(row=row, column=1)
    return lbl

def make_widget(title, items, row):
    lbl = make_label(title, row)
    buttons = []
    row += 1
    for col, drink in enumerate(items):
        radio_button = Radiobutton(root, selectcolor="grey", text=drink, variable=spiritvar, value=drink, 
                               bd=1, bg="#FFEFDB", relief="solid", font="Times 32", width=14)
        radio_button.config(indicatoron=0)
        column =  col%3
        radio_button.grid(row=row, column=column)
        buttons.append(radio_button)
        if column == 2:
            row += 1
    return (row, {'label':lbl, 'buttons':buttons})
    
def drink():
    vending.make_drink(spirit=spiritvar.get(), shots=shotsvar.get(), mixer=mixervar.get())

if __name__ == '__main__':
    root = Tk()
    root.geometry("1024x600+0+0")
    root.configure(bg = "black")
     
    spiritvar = StringVar()
    shotsvar = StringVar()
    mixervar = StringVar()
    widgets = []
    row = 0    
    for option, available_selections in vending.vending_options.items():
        row, widget = make_widget(title=option, items=available_selections, row=row)
        widgets.append(widget)
    b1 = Button(root, text="Make", bd=1, bg="white", relief="solid",
                font="Times 32", width=14, command=drink)
    b1.grid(row=row,column=1)
    root.mainloop()
