亲爱的StackOverflow社区，
我正在为我的足球赛季处理计划建立一个Tkinter GUI。具体来说，我有一个包含游戏输入功能的可视化表示的类。此类包含OptionMenu小部件，分别提示用户选择团队及其分数。
这里的问题是我在提交游戏后无法解决如何重置OptionMenu的问题。在我详细说明之前，让我提供代码;
class Game_View():
'''
This class contains the visual representation of the game input feature.
'''
def __init__(self, frame, parent, season, selected_hometeam, selected_awayteam, selected_homegoal, selected_awaygoal):
self.frame=frame
self.parent=parent
self.season=season
self.insert_game_prompt()
self.insert_input_fixture_button()
self.selected_hometeam=selected_hometeam
self.selected_homegoal=selected_homegoal
self.selected_awayteam=selected_awayteam
self.selected_awaygoal=selected_awaygoal
def insert_game_prompt(self):
'''
This method creates the drop-down menus that allow the user to provide information about a fixture.
In specific, the user inputs the home team, the away team, and their scored goals.
'''
self.goal_list=[]
i=0
while i<11:
self.goal_list.append(i)
i+=1
#The record for scored goals in the a Premier League match ever is 9;
# (Man Utd v. Ipswich town, 9 - 0, 4th of March 1995.)
# Hence, this program allows the user to exceed this record by 1, as the
# upper limit of possible scored goals is 10.
window_title_1=Label(self.frame, text="Home Team:", bg='grey')
window_title_1.pack()
self.selected_hometeam=StringVar()
self.selected_hometeam.set('Provide Team')
hometeam_prompt=OptionMenu(self.frame, self.selected_hometeam, *self.season.team_names, command=self.assign_hometeam)
hometeam_prompt.config(bg='grey')
hometeam_prompt.pack()
self.selected_homegoal=StringVar()
self.selected_homegoal.set('Provide Score')
homegoal_prompt=OptionMenu(self.frame, self.selected_homegoal, *self.goal_list, command=self.assign_homegoal)
homegoal_prompt.config(bg='grey')
homegoal_prompt.pack()
window_title_2=Label(self.frame, text="\nAway Team:", bg='grey')
window_title_2.pack()
self.selected_awayteam=StringVar()
self.selected_awayteam.set('Provide Team')
awayteam_prompt=OptionMenu(self.frame, self.selected_awayteam, *self.season.team_names, command=self.assign_awayteam)
awayteam_prompt.config(bg='grey')
awayteam_prompt.pack()
self.selected_awaygoal=StringVar()
self.selected_awaygoal.set('Provide Score')
awaygoal_prompt=OptionMenu(self.frame, self.selected_awaygoal, *self.goal_list, command=self.assign_awaygoal)
awaygoal_prompt.config(bg='grey')
awaygoal_prompt.pack()
def assign_hometeam(self, team):
'''
This method updates the class attribute with the home team selected by the user.
'''
self.selected_hometeam=team
def assign_awayteam(self, team):
'''
This method updates the class attribute with the away team selected by the user.
'''
self.selected_awayteam=team
def assign_homegoal(self, goal):
'''
This method updates the class attribute with the goals scored by the home team.
'''
self.selected_homegoal=goal
def assign_awaygoal(self, goal):
'''
This method updates the class attribute with the goals scored by the away team.
'''
self.selected_awaygoal=goal
def insert_input_fixture_button(self):
'''
This method inserts a button that the user presses when he/she wants to input a match entry.
'''
input_fixture_button=Button(self.frame, height=1, width=10, text='Input fixture', highlightbackground='grey')
input_fixture_button.bind('<Button-1>', self.submit_fixture)
input_fixture_button.pack()
def submit_fixture(self, a):
'''
When the Insert input button is pressed, this method sends the information provided by the user to the match handling logic
in the Season class. Secondly, it prompts a new rendering of the table. Thirdly, it resets the input fixture button.
'''
self.season.submit_match_data(self.selected_hometeam, self.selected_awayteam, self.selected_homegoal, self.selected_awaygoal)
self.parent.render_season_view()
如您所见，单击Input Fixture按钮会触发submit_fixture方法，该方法在调用其他类中的匹配逻辑时使用当前选定的OptionMenu选项（因此，其类属性）。目前，单击“输入夹具”按钮后，OptionMenu选项仍然存在，但我希望它们分别重置为“提供团队（分数）”。
我试过在submit_fixture方法中调用最后一个“re-render”方法;
（1）通过.destroy（）/ .forget（）
销毁OptionMenus（2）重置类属性（selected_home（away）_team（goal））
（3）调用self.insert_game_prompt（）重新创建OptionMenus
但是，无论我如何配置此重新渲染方法，单击“输入夹具”按钮后选项仍然存在。首先;是否有更简单的方法来重置选项而不是销毁/创建它们？当然，我没有运气搜索论坛。其次，你对我的错误有所了解吗？
最佳， JG
