[Solved]Creating a loop that searches a specific variable

[Doeny]

Hi, I was wondering if there is a way to search for e.g. three variables from a whole dict that meets certain requirements.

So let's say we have a...

Code: Select all

default switch = buttons("button_1", 0, 1, 0 ,4 , 5, 0} #in sequence: image, and other corresponding values

screen value_screen:
	vbox:
		text "[value_1]
		text "[value_2]
		text "[value_3]

Can I make it so the text (values 1-3) is listed as every button's value that is higher than/isn't equal 0?

Not sure I'm following. You also have typos in your code. What is this "buttons" class anyway? It's not a dict, that's for sure. You have to post the corresponding class if you need help.

The class itself isn't too complex. Just a placeholder for test purposes.

Code: Select all

init python:
    class buttons:
        def __init__(self, img, place1, place2, place3, place4, place5, place6):
            self.img = img
            self.place1= place1
            self.place2= place2
            self.place3= place3
            self.place4= place4
            self.place5= place5
            self.place6 = place6

What I'm trying to do is write a code that checks every 'place' variable in which value in higher than 0. And yes, I know you don't really need a class for what I've given, but at this point it's just a placeholder.

1) If you have a bunch of varaibles with name that differs only by the number on the end, you really want to use a list there.

Code: Select all

init python:
    class buttons:
        def __init__(self, img, place1, place2, place3, place4, place5, place6):
            self.img = img
            self.places = [place1, place2, place3, place4, place5, place6]

# Or even
        def __init__(self, img, *args):
            self.img = img
            assert len(args) == 6
            self.places = list(args)

After that you can simply iterate over the list and pick values you need. Or use built-ins:

Code: Select all

    def extract_non_zero(self):
        return filter(None, self.places) # This returns a list of non-zero numbers

Then you can do whatever you like with this list:

Code: Select all

screen value_screen:
    vbox:
        for item in switch.extract_non_zero():
            text str(item)

Code: Select all

init python:
    class buttons:
        def __init__(self, img, place1, place2, place3, place4, place5, place6):
            self.img = img
            self.places = [place1, place2, place3, place4, place5, place6]

    def extract_non_zero(self):
        return filter(None, self.places) # This returns a list of non-zero numbers
        
screen value_screen:
    vbox:
        for item in switch.extract_non_zero():
            text str(item)

For the first method it gives me an error saying that 'name switch" is not definied

I was relying on code you have shown, and switch was defined there...

My bad, I forgot it's name after changing it.

    vbox:
        for item in switch.extract_non_zero():
            text str(item)

It's something I realized just by now, but the extract_non_zero method doesn't update it's value as one of the buttons are changed. Maybe 'cause it's pre-defined or I overlooked something with my code. If I'm right with the first case, is there a way to fit it into updated values?

This depends on your code. Maybe you are changing external list which is not used by switch. Maybe you are changing it by something not restarting interaction. Maybe something else...
