有人知道如何通过标签增加分数吗?

Question

基本上我已经创建了一个简单的数学游戏，并使其显示问题是否正确或错误，但我无法获得分数更新，也有人知道我如何才能让问题刷新到另一个问题，我尝试了app.update ?:

            self.a1button = Tkinter.Button(self, background="blue",foreground="white", text = (random_row.A1), command = self.QUESTION1)
            self.a1button.grid(row = 9, column = 1, sticky = 'W')
            self.label5 = Tkinter.Label(self, text = "Score:")
            self.label5.grid(row = 14, column = 1, columnspan = 5, sticky = 'S')
            self.label7 = Tkinter.Label(self, text = 0 )
            self.label7.grid(row = 14, column = 6, columnspan = 1, sticky = 'E')
def QUESTION1(self):
    if self.a1button['text'] == self.label6['text']:
        tkMessageBox.showinfo("CORRECT", "WELL DONE")
        label7 = +100
        app.refresh
    else:
        tkMessageBox.showinfo("INCORRECT", "YOU FULLY GOT IT WRONG :/")
        label7 = -100
        app.refresh

Answer 1

您需要首先从标签中读取当前得分，添加或减去100分，然后再次设置标签:

score = int(self.label7.get())
score += 100
self.label7.set(str(score))
app.refresh()

注意，您还需要调用 refresh方法，而不仅仅是引用它。

使用-=进行减法
