Delete a row in Kivy's BoxLayout

With Kivy, I want a layout that is different when the window size is portrait or landscape (a grid of buttons, and for exemple the buttons on a row are shown in a column).
I tried first to hide some widgets, but that doesn't work well (even at a size of 0, some text appears, and this doesn't work with spacing)
So I wanted to delete a row directly, it worked, but...
The space for the raw remains with, like this
I tried to delete the second row, but there is now a gap.
Here is the code for that example
test3.kv file
<MDBoxLayout>:
spacing:5
<MyLayout>:
MDBoxLayout:
orientation: "vertical"
size: root.width, root.height

Is this something missing in my code, or should I try another method to change dynamically the layout?

How do i add a signature/paint method to a screen in my app in either kv lang or normal kivy?

how do i add buttons to my paintScreen class without the on_touch_down/move interfering and making it so that i draw within a BoxLayout canvas and separate the buttons in a different box so that it wont draw over the buttons? This is the current problem i am having. Also if that problem is fixed then would i be able to save that drawing as an img if i use export_to_png

how to use GridLayout in TabeedPanel using kivy in python

I am trying to make a GUI in python using kivy and TabeedPanel . some problems are coming for putting on exact location of label, TextInput , button. I'm unable to put multiple label, TextInput altogether. That's why I commented in the code. I tried GridLayout also, but Unable to arrange exactly.
Can you help me? Thanks in advance.
from kivy.app import App
from kivy.uix.tabbedpanel import TabbedPanel, TabbedPanelItem
from kivy.lang import Builder
from kivy.uix.checkbox import CheckBox
from kivy.uix.button import Button
from kivy.app import App
from kivy.uix.textinput import TextInput
import json
Builder.load_string("""
<Test>:
do_default_tab: False
TabbedPanelItem:
text: 'page1'
BoxLayout:

Following your example, you can use BoxLayouts but you need to nest them correctly:
from kivy.app import App
from kivy.uix.tabbedpanel import TabbedPanel
from kivy.lang import Builder
Builder.load_string("""

orientation: 'vertical'
size_hint_x: 1
Label:
text: 'label'
Label:
text: 'label'
Label:

BoxLayout:
spacing: 50
orientation: 'vertical'
Label:

""")
class Test(TabbedPanel):
pass
class MyApp(App):
def build(self):
test = Test()
return test
if __name__ == '__main__':
MyApp().run()
Output:

Here's an example using GridLayout that I made a reference to in your other question. FYI, there are many ways you could go about this. I personally like using gridlayout with forms because it's easy to put then ScrollViews if need be.
Read up on the kv language here to help keep things DRY and other things. If a widget is defined in kv, then you don't need to import them at the top of your file.
Example:
from kivy.app import App
from kivy.uix.tabbedpanel import TabbedPanel
from kivy.lang import Builder
Builder.load_string("""
<MyLabel#Label>:
size_hint: (None, None)

size: (600, 100)
<MyButton#Button>:
size_hint: (None, None)
size: (400, 100)
<MyCheckBox#AnchorLayout>:
# I'm nesting the checkbox here b/c it is hard to see if the background is not lightened.
size_hint: (None, None)
size: (100, 100)

How should I set a global variable in kivy Python?

My application is simple, the ScreenTwo is showing a form 'Parametreur' with various options to be entered.
What I'm trying to do is to set a 'save' button at the end of this form that will register into a list called 'resultat' all the options furfilled so far leaving '0' in the empty inputs.
The global variable 'resultat' would look like this ['blabla','15/06/2018','31/12/1999','6'].

Where and How should I set my global variable 'resultat' (which is a list)?
I've solved my problem but I still don't understand how does it work. Setting a variable is Kivy doesn't need to set it in the Python code. But how do Kivy and Python know about its type? Right now, it works as a list without me defining it such as (I intended it to be a list anyway).
How could I set a variable as tuple for example?
