Maybe someone would give me a hint what direction have I go in, couz I"ve stucked on my problem. I will be very grateful. So, the thing is I am working on my Kivy project. The task is to evoke a line with 2 buttons, one of them have to rename another in the line. Actually it works, but only with 1 row. If we have set of lines, 5 for instance, whatever line you would choose, only first button in first line will be renamed, not specified one. I am trying to explore indexing of button set and lists of buttons but unsuccessfully
py code is here:
class Radiators(Screen):
btn_lst = []
btn_cn_lst = []
i = 0
cn = 0
def add_button_radiator_setting(self):
self.i += 1
self.btn_rad = Button(text="room")
self.btn_lst.append(self.btn_rad)
self.ids.button_grid_radiators.add_widget(self.btn_rad)
self.cn = self.cn + 1
self.btn_context = Button(text="...")
self.btn_cn_lst.append(self.btn_context)
self.btn_cn_lst[self.cn-1].bind(on_press = self.rename_btn)
self.ids.button_context_menu.add_widget(self.btn_context)
def reject_button_radiator_setting(self):
self.ids.button_grid_radiators.remove_widget(self.btn_lst[self.i-1])
self.i -= 1
self.btn_lst.pop(-1)
self.ids.button_context_menu.remove_widget(self.btn_cn_lst[self.cn-1])
self.cn -= 1
self.btn_cn_lst.pop(-1)
def rename_btn(self, ind):
self.ids.button_grid_radiators.children[self.cn-1].text = str(input("enter: "))
class radiatorsApp(App):
pass
radiatorsApp().run()
kivy code is here:

Button:

Button:

Button:
text: "+"
on_press: root.add_button_radiator_setting()
The on_press method gets the Button that was pressed as an argument. You can use that to find the other Button:
def rename_btn(self, pressed_button):
index = self.btn_cn_lst.index(pressed_button) # get index in list of Buttons
butt = self.btn_lst[index] # get the Button from the other list at the same index
butt.text = str(input("enter: ")) # change the text of the Button
