如果选择特定选项，如何从组合框中获取值或执行函数？我想传递值（例如＆＃34; zip＆＃34;）而不是列表中的索引，因为列表每次都会根据用户输入进行更改。
optentry = StringVar()
optdefault = ["txt", "exe", "py", "zip", "rar", "pdf"]
opts = optdefault
comboend = OptionMenu(frameend, optentry, "All", *opts)
buttontest = Button(frameend, text="Print", command=lambda: print(optentry))
