python - 我可以将所有这些输入作为 for 循环吗？（长袍）

Question

我想制作一个 9x9 表，用户可以在其中插入值。正如您在代码中看到的那样，我使用了大量的语句来实现这个目的。我必须分别进行每个输入。我希望是否有一种方法可以让我使用 for 循环或其他方法来使这些语句消失。我不知道是否有可能做到这一点。请帮帮我。

另外，谁能告诉如何在应用程序的中心保留一个按钮？我不得不为此功能使用填充。还有其他方法吗？我试过style=Pack(alignment=CENTER)但没有成功。

Yep, a simple for loop and list or dictionary could help you out. Maybe something like this to replace the input prompts?

self.t = []

for i in range(11, 100):
    if i % 10:
        if not str(i).endswith("3") and not str(i).endswith("6"):
            self.t.append(toga.NumberInput(min_value=0, max_value=9,
                                           default=0, style=Pack(width=50)))
        else:
             self.t.append(toga.NumberInput(min_value=0, max_value=9,
                                           default=0, style=Pack(width=50, padding=(0, 5, 0, 0))))

Then you could make the rows using:

self.row1 = toga.Box(
            children=[self.t[0]],
                        self.t[1],
                        self.t[2],
                        self.t[3],
                        self.t[4],
                        self.t[5],
                        self.t[6],
                        self.t[7],
                        self.t[8], ],
            style = Pack(flex=1, alignment=CENTER)
            )

I'm sure this can be improved but does this work with your code?
