Can I take the all these inputs as a for loop? (toga)

Question

I wanted to make a 9x9 table where the value can be inserted by the user. As you can see in the code that I have used an awful lot of statements for fulfilling this purpose. I had to make each input separately. I was hoping if there was a way for me to use for loop or something else to make these statements go away. I don't know if it is even possible to do this. Please help me out.

Also, can anyone tell how to keep a button in the center of the application? I had to use padding for this function. Is there any other way? I tried style=Pack(alignment=CENTER) but didn't work out.

        show the main window.

The output that I got using this is:

You could have a `for _ in range(99):` loop where you add the `toga.NumberInput` inputs into a list, then give slices of the list to `toga.Box`. This seems more suited for [codereview.se] though (at least the first part of the question), providing the code is complete and works. — Carcigenicate, Oct 27 '20 at 22:02

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?

Thank you so much. It really helped. Please comment if you can also help with the alignment for the button in the center. Anyways, thank you. — Aunny, Oct 28 '20 at 06:04
Sorry man, I can't help there as I can't see anything specifically about that in their documentation and toga isn't working on my system for some reason. I suggest posting another question specifically for that though — Rolv Apneseth, Oct 28 '20 at 15:38

Can I take the all these inputs as a for loop? (toga)
