如何存储多个不同的Python Tkinter OptionMenu选项

Question

我创建了一个创建和打包一些下拉菜单的功能。我现在面临的唯一问题是如何将所有6个菜单中的选择存储到列表中？我能够通过func（）方法访问菜单选项，但我坚持如何存储所有这些？理想情况下，id喜欢将所有6个选项存储在列表中，这可能吗？

def func(value):
     x = value
     print(value)


def GetEntry(x):
    var = StringVar()    
    var.set('select one')    
    formatted = x.get().split()##gets the entry and forms a list
    getMeal = CsvLoadSearch(u, formatted)
    meal = OptionMenu(root, var, *getMeal, command = func ).pack()        

mealOneButton = Button(root, text = "query database", command = lambda : GetEntry(mealOneString)) 
mealTwoButton = Button(root, text = "query database", command = lambda : GetEntry(mealTwoString))
mealThreeButton = Button(root, text = "query database", command = lambda : GetEntry(mealThreeString))
mealFourButton = Button(root, text = "query database", command = lambda : GetEntry(mealFourString))
mealFiveButton = Button(root, text = "query database", command = lambda : GetEntry(mealFiveString))
mealSixButton = Button(root, text = "query database", command = lambda : GetEntry(mealSixString)) 

这是下面的节目：

from tkinter import *
from tkinter import ttk
import csv
import os

u = "C:\\Users\\luke daniels\\Documents\\fooddata.csv"

"""
   Loads csv and compares elements from foodList with current row.
   returns a list of rows that match elements in foodList.
"""
def CsvLoadSearch(u, foodList):
    results = []

    inputfile = open(u)            
    for row in csv.reader(inputfile):
        for food in foodList:
            if food in row[0]:
                results.append(row)
                ##print(row)
    return results

##gets selection from drop down
def func(value):
    x = value   

def GetEntry(x):
    var = StringVar()    
    var.set('select one')    
    formatted = x.get().split()##gets the entry and forms a list
    getMeal = CsvLoadSearch(u, formatted)
    meal = OptionMenu(root, var, *getMeal, command = func ).pack()
