我有一個組合框，我在其中選擇性別男性或女性。然后我有另一個組合框，現在顯示所有人的名字（不區分性別）。
我想從第一個組合框中選擇男性，并在第二個組合框中自動顯示（不帶按鈕）男性名稱。女性名字也是如此。謝謝

selected = gender.get()
# get the names for selected gender
all_name['value'] = [x['Name'] for x in [John, Linda, Martin] if x['Gender'] == selected]
all_name.set('') # clear current selection
gender.bind('<<ComboboxSelected>>', on_gender_selected)
