OptionMenu ウィジェットで選択した機能を呼び出す動的ボタンを作成する方法を知りたいです。

最後から 2 番目の行 [-2] で、「command=daily_return」を「command=var」に置き換えましたが、機能しません。

助言がありますか？一番

場合によっては、最も簡単な解決策が Good Enough です。

def do_something():
    # define a mapping from the choice value to a function name
    func_map = {
        "daily_choices": daily_choices,
        "value_at_risk": value_at_risk,
        "cumulative_return": cumulative_return,
    }
    # using the map, get the function
    function = func_map[var.get()]

    # call the function
    function()

...        
Button(..., command=do_something)
