How to store a lot of data from a treeview in a list, Python

I have the following problem with this part of my code I explain
What this function does is get the data from the DB and then fill the Treeview
def obtenerDatos():
cursor = conexion.cursor()
cursor.execute("SELECT empresas.empresa, picos.pico, tamano_precio.tamano FROM cilindros, empresas, picos, tamano_precio WHERE empresa_id = empresas.id AND pico_id = picos.id AND tamano_id = tamano_precio.id AND jefesf_id =? ORDER BY cilindros.tamano_id ASC", (validarCi,))
datosConsulta = cursor.fetchall()
return datosConsulta
cursor.close()
cursor.execute("SELECT * FROM jefesf WHERE ci =?", (validarCi,))
Then I use an if to check if there are people with that data registered in the DB
if cursor.fetchall():
ventana3 = Toplevel()
datosConsulta = obtenerDatos()
contador = 0
datosJefes = ttk.Treeview(ventana3, columns=("colum1", "colum2"))
datosJefes.column("#0", width=80)
datosJefes.column("colum1", width=80, anchor=CENTER)
datosJefes.column("colum2", width=80, anchor=CENTER)
datosJefes.heading("#0", text="Empresa")
datosJefes.heading("colum1", text="Pico")
datosJefes.heading("colum2", text="Tamaño")
Here I begin to fill the Treview with the data
for listado in datosConsulta:
datosJefes.insert("", "end", text=listado[0], values=(listado[1], listado[2]))
datosJefes.pack()
This is where I have the problem, what I want to do is to be able to select records from the treview and that those records are saved in a multilist and print them to me by console, but I don't know how
def SeleccinarRegistro():
global listaCilin
global dato1
global dato2
listaCilin = []
dato = datosJefes.item(datosJefes.selection())
datos = list(dato.values())
dato1 = datos[0]
dato2 = datos[2][0]
dato3 = datos[2][1]
I tried with a While loop but it generates an infinite loop, and my idea was every time I press the button the loop runs and saves the elements in the list
while SeleccinarRegistro:
listaCilin.append([dato1, dato2, dato3, validarCi])
print("Empresa: ", dato1)
print("Pico: ", dato2)
print("Tamano: ", dato3)
print(listaCilin)
Button(ventana3, text="Seleccionar", command=SeleccinarRegistro).pack()

Sum values ​from a treeview column

Good,
I'm trying to sum the values ​​of a column, while inputting it. Since I put a code in the entry and check if it exists and put it in columns in treeview, and I would like to add only the "price" values, but I can't do it, I get the data from the price column, but I can't get if This 5.99 I have entered another 5.99 add up and give me a total, as I add a price.
What I can be doing wrong? or what I have wrong
Any additional information would be appreciated.
def Cesta(self):

Everything else is going well for me, but the part in which I want to add the results of the price column does not
What am I doing wrong, to be able to add the values ​​of the prices column every time I insert a new product?

I have already managed to solve the error, the new price is already added to the old one, thanks for making me reflect on it.
for self.x2 in self.r_codigo:
print (self.x2["nombre"], self.x2["talla"], self.x2["precio"]+"€")

self.total = 0
for self.item in self.tree.get_children():
self.celda = float(self.tree.set(self.item,"col2"))
self.total+=self.celda

Set value on ttk.Checkbutton from a ttk.ComboBox

Hi i trying to set data on checkbutton from a combobox list, and then save this on json file. I have this codes from the program and save function.
def create_odontograma():
#Odontograma
global selected_patologias
global selected_p
selected_patologias = tk.StringVar()
patologias = ttk.Combobox(odontograma_frame, textvariable=selected_patologias)
patologias.grid(row=10,column=37)
patologias["values"] = ["Caries", "Endodoncia", "Exodoncia", "Corona", "Puente"]
global e18d
global e18o
global e18m
global e18v
global e18p
e18d = tk.StringVar()
e18o = tk.StringVar()
e18m = tk.StringVar()
e18v = tk.StringVar()
e18p = tk.StringVar()
elemento18L = ttk.Label(odontograma_frame, text="18")
elemento18L.grid(column=7, row=1)
elemento18D = ttk.Checkbutton(odontograma_frame, width=0 ,offvalue='Sano', onvalue=f'{selected_patologias.get()}', variable=e18d)
elemento18D.grid(column=6, row=3)
elemento18O = ttk.Checkbutton(odontograma_frame, width=0,offvalue=f'Sano', onvalue=f'{e18o}')
elemento18O.grid(column=7, row=3, padx= 1)
elemento18M = ttk.Checkbutton(odontograma_frame, width=0,offvalue=f'Sano', onvalue=f'{e18m}')

elemento18P = ttk.Checkbutton(odontograma_frame, width=0,offvalue=f'Sano', onvalue=f'{e18p}')
elemento18P.grid(column=7, row=4)
And here is the save function for json file

print (selected_patologias.get())

# Create the directory

with open(f'grupopacientes/{nombre.get()}.json','w') as document:
json.dump(pacientes, document, indent=3)
messagebox.showinfo("Informacion","Se ha añadido el paciente correctamente")
I would like to get data from selected_patologias.get() and put in OnValue on checkbutton atributes, then get this "onvalue" and carry to json.

Combobox in tkinter not giving correct .get() value

This so weird, like i am trying to use if statement and the selection in combobox to do some specific command and when combobox value is selected to 'full_name' (part of elif) they return an messagebox, that is supposed to be showed only when the first if statement is executed but according to the conditions its supposed to return the elif part but it returns the if part. Is there a mistake in my code? If the Q is unclear please try referring the code or lemme knw :) Thanks in advance.

The problem is this line:
if a == 'id' or 'emirate_id' or...
This statement always return True. It is evaluating whether a=="id" or emirate_id is True, and a non-empty string always returns True.
You can be explicit and use:
if a == 'id' or a == 'emirate_id' or ...
Or better yet, use keyword in:
if a in ("id", "emirate_id",...)

Kivy reload Buttons(via function)on app startup

Hi i'm pretty new with python and kivy , im trying to do a simple "to do" app.. My code looks horrible, i know, and im sorry for that..
I have a table in sqlite3 with some information stored in it. I would like to call a function that query this table on app start up. I can't figure out how to make it work.. Here is my code
Python:

some pieces of code are unused don't worry about it.
Function i need to call is reloadSession that query table and then with the information retrieved create n buttons...
As you can see, in the SmsButton class(in KV) call that function(ON_PRESS), i need to do the same thing but automatically on app start up... How can i do that??
Sorry for my bad english and coding.. Im new, im trying a lot of stuff, i would appreciate your help.
Thank you.
Yvan.
EDIT: removed unused code
EDIT : #bj0
thanks for the tips.. i've tryied to use build function in alla the way i know. but it doesnt work ...i get this error
("'Test' object has no attribute 'links_grid'",)
the code im using now is this..
class Test(App):
def build(self):
try:
con = sqlite3.connect('localdb.db')
cur = con.cursor()
cur.execute("select * from localtb")
data = cur.fetchall()
con.close()
for x in data:
reload_Element = str(x[0])
if x[1] == 0:
print "in if: ", x[1]
link_button = LinkButton(text = reload_Element,background_color = [83,0,0,1])
else:
print "in else: ", x[1]
link_button = LinkButton(text = reload_Element,background_color = [0,83,0,1])
self.links_grid.add_widget(link_button)
except Exception as inst:
print inst.args
print "non va"
obviously Test class has no links_grid attribute.. but how can i solve this problem ?
Thanks again
