如何使用参数在tkinter中填充OptionMenu？

Question

目前我使用tkinter制作了一个下拉菜单的基本模板，其中包含三个参数1,2,3。

from tkinter import *

master = Tk()

variable = StringVar()
variable.set("one") # default value

w = OptionMenu(master, variable, "one", "two", "three")
w.pack()

mainloop()

为了更清晰，请参见上图。

现在我有30个键值对的字典，如何将它们填充为OptionMenu中的选项。 词典：

"Belgium (Dutch)": "nl_be",
                 "Hungary": "hu_hu",
                 "Chile": "es_cl",
                 "Belgium (French)": "fr_be",
                 "Mexico": "es_mx",
                 "Hong Kong": "hk",
                 "Turkey": "tr_tr",
                 "Ireland": "en_ie",
                 "Ghana": "en_gh",
                 "Argentina": "es_ar",
                 "Slovakia": "sk_sk",

我只想将词典的键作为optionmenu中的选项。 而不是在OptionMenu（）中传递字典的每个键是他们的任何智能技术。

您可以使用*将列表解压缩为多个参数

OptionMenu(master, variable, *data.keys())

完整

data = {
"Belgium (Dutch)": "nl_be",
 "Hungary": "hu_hu",
 "Chile": "es_cl",
 "Belgium (French)": "fr_be",
 "Mexico": "es_mx",
 "Hong Kong": "hk",
 "Turkey": "tr_tr",
 "Ireland": "en_ie",
 "Ghana": "en_gh",
 "Argentina": "es_ar",
 "Slovakia": "sk_sk",
}

from tkinter import *

master = Tk()

variable = StringVar()
variable.set("one") # default value

w = OptionMenu(master, variable, *data.keys())
w.pack()

mainloop()
