我正在尝试为我在学校做的一个 IT 项目组合一个 python 程序，它正在我的脑海里！我对python很陌生，所以我在这里真的很挣扎。

无论如何，我正在创建的程序应该将数字转换为单词（英语和毛利语）。例如，如果用户单击“1”，则屏幕上的图像在选择英语时变为“一”，而在选择毛利语时变为“tahi”。我有两个列表，每种语言一个（我只使用数字 1-10），当用户单击下拉列表中的一种语言时，我需要更改通过我的 number_converter 函数传递的列表。

我一直在尝试通过在 number_converter 函数中使用一个变量来执行此操作，该变量被两个列表名称中的任何一个替换。抱歉，如果这一切都非常混乱，我自己很难理解！无论如何，这是我的代码，也许你可以弄清楚：

# Number Converter Version 1.04

import tkinter, sys

class newpulldownlist:
# Creates a pull-down list of options through mypulldown = newpulldownlist(parent,     [array of options], command)
# mypulldown.value() returns the selected item
# mypulldown.chngevlue("to this") forces a selection change
# mypulldown.options (without brackets) returns an array of the option choices
# By default, fist item in the list is pre-selected.
def __init__ (self, parent, valuearray, cmd):

    self.options = valuearray

    self.listvariable = tkinter.StringVar()
    self.listvariable.set(valuearray[0])
    self.guilist = tkinter.OptionMenu(parent, self.listvariable, *valuearray, command = cmd)
    self.guilist.configure(width = "0")
    self.guilist.pack()

def value(self):
    return self.listvariable.get()

def changevalue(self, tothis):
    self.listvariable.set(tothis)

class newbutton:
# Create a new button as mybutton = newbutton(parent, x, y, startingtext, command)
def __init__ (self, parent, x, y, label, cmd):
    self.width = x
    self.height = y
    self.label = label

    self.guibut = tkinter.Button(parent, width = x, height = y, text = label, command = cmd)
    self.guibut.pack(side = "left")

def number_select(n):                       # Image changing function, calls images from the 'number' array.
global language
print("You pressed", n, ".")            # One function is used to streamline the code and avoid having a function for each number.
picture.delete('all')
newpic = picture.create_image(602, 2, image = language[n], anchor = "n")

def select(self):
options = lang_list.value()
print(lang_list.value())

# Window.

appwindow = tkinter.Tk()    # Makes window
appwindow.title("Number Converter")

rightside = tkinter.Frame(appwindow)
rightside.pack(side = tkinter.RIGHT)

topside = tkinter.Frame(appwindow)
topside.pack(side = tkinter.TOP)

bottomside = tkinter.Frame(appwindow)
bottomside.pack(side = tkinter.BOTTOM)

picture = tkinter.Canvas(topside, width = 1200, height = 70, bg = "white")
picture.pack()

如果我理解正确，我认为我的方法是使用字典。你会做类似的事情numbers = {'maori': maori, 'english': english}，然后调用language = numbers['maori']返回列表maori。因此，您的语言下拉菜单可以只更改'english'和之间的字符串变量'maori'，您将其传递给字典以选择适当的语言。

编辑：这里有更多关于字典的信息。
