Kivy multiple toggle buttons all read in a single function - function

Question

Trying to have multiple toggle buttons on a single screen be "saved" when a button is pressed. I am trying to take the values from the .kv into the python code to save. Was trying to use the gender1: gender1 --- gender1.self to try and objectproperty in the python code, but would have to do that for every button, if that is even a solution?
.kv
<UserProfile>:
name: "profile"
gender1: gender1.__self__
BoxLayout:
BoxLayout:
orientation: 'vertical'
Label:
text: 'Gender'
ToggleButton:
id: gender1
text: 'Male'
group: 'sex'
state: 'down'
ToggleButton:
id: gender2
text: 'Female'
group: 'sex'
ToggleButton:
id: gender3
text: 'Mixed'
group: 'sex'
BoxLayout:
orientation: 'vertical'
Label:
text: 'Hand'
ToggleButton:
id: hand1
text: 'Right'
group: 'hand'
state: 'down'
ToggleButton:
id: hand2
text: 'Left'
group: 'hand'
BoxLayout:
orientation: 'vertical'
Label:
text: 'Position'
ToggleButton:
id: position1
text: 'Forward'
state: 'down'
ToggleButton:
id:position2
text: 'Defense'
ToggleButton:
id:position3
text: 'Goalie'
Button:
text: 'Submit'
on_press: root.checkstate()
.py
class UserProfile(Screen):
def checkstate(self, **kwargs):
buttonids = []
for a in self.ids:
buttonids.append(a)
print(buttonids)
for id in buttonids:
print(self.{id}.state)
# a = self.ids
# for b in a:
# c = self.b.state
# print(c)
Was trying to show a couple ways I attempted...
In addition, if someone could possibly provide a decent tutorial or link to a good local storage example I'd appreciate that as well...
