Quiz listbox items displaying in one line

I am trying to show the options for quiz questions in a listbox. The value will later be retrieved with a button. They show as one line instead of different listed items. I think it has something to do with the list and how it is formatted, but I am not sure how to fix this. How can I fix this?
from tkinter import *
from random import randint
import random
from string import ascii_lowercase
QuizFrame = Tk()
NUM_QUESTIONS_PER_QUIZ = 4
QUESTIONS = {
"What day of the week is it?": [
"Monday",
"Tuesday",
"Wednesday",
"Thursday"
],
"What is the first state?": [
"Delaware",
"Maryland",
"Texas",
"Maine"
],
}
num_questions = min(NUM_QUESTIONS_PER_QUIZ, len(QUESTIONS))
questions = random.sample(list(QUESTIONS.items()), k=num_questions)
Question_Label = Label(QuizFrame, text="", font=("Helvetica", 20))
Question_Label.grid(row=3, column=1)
for num, (question, alternatives) in enumerate(questions, start=1):
Question_Label.config(text=question)
correct_answer = alternatives[0]
labeled_alternatives = dict(
zip(ascii_lowercase, random.sample(alternatives, k=len(alternatives)))
)
my_listbox=Listbox(QuizFrame)
my_listbox.grid(row=6, column=1)
my_list=[labeled_alternatives]
for item in my_list:
my_listbox.insert(END,item)
QuizFrame.mainloop()

my_list only contains one item, labeled_alternative, so when you iterate it in the for loop, the entire dictionary gets inserted. Instead, you want to iterate labeled_alternatives.items() to get the keys and values for each item in your dictionary. Change the for loop to
for k, v in labeled_alternatives.items():
my_listbox.insert(END, k + ": " + v)

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.

Extract a database field via 2 combined comboboxes. Problem in the function for extracting

By selecting two comboboxes (combined with bind), I would like to extract the ID of a field from Table1 and insert it into Table2. I have no problems extracting a field based on a combobox, but I have problems extracting a field based on 2 comboboxes, because they are combined with each other. The problem is only def id_rounds() function.
I have two comboboxes: one in which I select the name of the "Tournament" and another in which I select the number of Rounds (from 1 to 38 different rounds for each tournament). To choose which tournament the tournament ID must match, I use the combobox combo_Tournaments and function def combo_tournaments; while to choose the number of the Round I use the combobox combo_Rounds and the combo_rounds function. By selecting the Tournament and / or Round, the relevant ID is also automatically entered (as well as the actual data). So each combobox puts in 2 things each, for a total of 4.
Here is the database:
CREATE TABLE "All_Tournament" (
"ID_Tournament" INTEGER,
"Tournament" TEXT,
PRIMARY KEY("Tournament" AUTOINCREMENT)
);
CREATE TABLE "All_Round" (
"ID_Round" INTEGER,
"Number_Round" INTEGER,
"ID_Tournament" INTEGER,
PRIMARY KEY("ID_Round" AUTOINCREMENT),
);
PROBLEM: Currently as I wrote the code of the function def id_rounds(), the ID of the selected Round is saved, but without exact correspondence to the chosen Tournament in the Tournament combobox. The problem is that each Tournament is each made up of 38 different Rounds, therefore in the All_Round table the numbers from 1 to 38 are repeated several times, each corresponding to the Tournament ID. For example Serie A from 1 to 38 Round; Serie B from 1 to 38 rounds; Premier League from 1 to 38 rounds. So I would like to enter the ID of the single Round corresponding to the Tournament (in relation to the tournament), because each tournament has 1 to 38 rounds, so there are many different "1 to 38 rounds" for each tournament.
#Combobox Tournament
lbl_Tournament = Label(root, text="Tournament", font=("Calibri", 11), bg="#E95420", fg="white")
lbl_Tournament.place(x=6, y=60)
combo_Tournaments = ttk.Combobox(root, font=("Calibri", 11), width=30, textvariable=campionato, state="readonly")
combo_Tournaments.place(x=180, y=60)
combo_Tournaments.set("Select")
combo_Tournaments['values'] = combo_tournaments()
combo_Tournaments.bind('<<ComboboxSelected>>', combo_teams)
lbl_Rounds = Label(root, text="Rounds", font=("Calibri", 11), bg="#E95420", fg="white")
lbl_Rounds.place(x=600, y=60)
combo_Rounds = ttk.Combobox(root, font=("Calibri", 11), width=30, textvariable=rounds, state="readonly")
combo_Rounds.place(x=680, y=60)
combo_Rounds.set("Select")
combo_Rounds['values'] = combo_campionati()
combo_Tournaments.bind('<<ComboboxSelected>>', combo_rounds, add=True)
def combo_tournaments():
tournaments = combo_tournaments.get()
cursor.execute('SELECT Tournament FROM All_Tournament')
result=[row[0] for row in cursor]
return result
def id_tournaments():
tournaments = combo_tournaments.get()
cursor.execute('SELECT ID_Tournament FROM All_Tournament WHERE Tournament=?',(tournaments,))
result=[row[0] for row in cursor]
return result[0]
def combo_rounds(event=None):
rounds = combo_rounds.get()
cursor.execute('SELECT Number_Round From All_Round WHERE ID_Tournament')
result=[row[0] for row in cursor]
combo_Rounds['value'] = result
return result
#THE PROBLEM IS HERE
def id_rounds():
rounds = combo_rounds.get()
cursor.execute('SELECT ID_Round FROM All_Round WHERE Number_Round=? AND Tournament=?',(rounds, tournaments))
result=[row[0] for row in cursor]
return result[0]
def combo_teams(event=None):
tournaments = combo_tournaments.get()
cursor.execute('SELECT s.Name_Teams FROM All_Teams s, All_Tournament c WHERE s.ID_Tournament=c.ID_Tournament AND c.Tournament = ?', (tournaments,))
result=[row[0] for row in cursor]
combo_Teams_1['values'] = result
combo_Teams_2['values'] = result
return result
WHAT DO I WANT TO GET? So I would like to obtain for example that: if from the Tournament combobox I select Serie A and then Round 1, in the Results table the ID of Round 1 should be entered but corresponding to Serie A. Or, another example, if from the Tournament combobox I select Serie B and then Round 1, the ID of Round 1 should be entered in the Results table but corresponding to Serie B.
QUESTION: How can I fix the function def id_rounds and which inserts the number of the Round in correspondence (in relation) to the tournament? Currently I only enter the ID of the selected Round in the combobox without matching the championship chosen in the tournament combobox.

Below is the modified code based on my understanding:
def combo_tournaments():
cursor.execute('SELECT Tournament FROM All_Tournament')
result=[row[0] for row in cursor]
return result
def combo_rounds(event=None):
# get all Number_Round for selected tournament
cursor.execute('''
SELECT Number_Round From All_Round r, All_Tournament t
WHERE r.ID_Tournament = t.ID_Tournament AND Tournament = ?''', (campionato.get(),))
result=[row[0] for row in cursor]
combo_Rounds['value'] = result # update combo_Rounds
rounds.set('Select') # reset Rounds selection
return result
def id_rounds(event=None):
# get the ID_Round based on selected tournament and Number_Round
cursor.execute('''
SELECT ID_Round FROM All_Round r, All_Tournament t
WHERE r.ID_Tournament = t.ID_Tournament AND Number_Round = ? AND Tournament = ?''',
(rounds.get(), campionato.get()))
result = cursor.fetchone()
if result:
print(result[0])
return result[0]
return None
...
campionato = StringVar()
rounds = StringVar()
#Combobox Tournament
lbl_Tournament = Label(root, text="Tournament", font=("Calibri", 11), bg="#E95420", fg="white")
lbl_Tournament.place(x=6, y=60)
combo_Tournaments = ttk.Combobox(root, font=("Calibri", 11), width=30, textvariable=campionato, state="readonly")
combo_Tournaments.place(x=180, y=60)
combo_Tournaments.set("Select")
combo_Tournaments['values'] = combo_tournaments()
combo_Tournaments.bind('<<ComboboxSelected>>', combo_rounds)
lbl_Rounds = Label(root, text="Rounds", font=("Calibri", 11), bg="#E95420", fg="white")
lbl_Rounds.place(x=600, y=60)
combo_Rounds = ttk.Combobox(root, font=("Calibri", 11), width=30, textvariable=rounds, state="readonly")
combo_Rounds.place(x=680, y=60)
combo_Rounds.set("Select")
combo_Rounds.bind('<<ComboboxSelected>>', id_rounds)
...
Note that I have used the campionato and rounds (StringVar) to get the selected tournament and Number_Round.

Summing values from treeview if row is empty Tkinter

I want to sum values from treeview column no matter if one of the rows is empty, also I want to delete that row when the Sum button is pressed. I wrote a code but I always get this error:
IndexError: string index out of range
This is the code:
from tkinter import*
from tkinter import ttk
myApp = Tk()
myApp.title(" Program ")
TotalEntry=Entry(myApp, width=18)
TotalEntry.grid(row=0,column=1, sticky="e", pady=5)
NewTree= ttk.Treeview(myApp, height=7)
NewTree['show'] = 'headings'
NewTree["columns"]=("1")
NewTree.column("1", width=80, anchor="center")
NewTree.heading("1", text="ID")
item = NewTree.insert("", "end", values=(2))
item = NewTree.insert("", "end", values=(""))
item = NewTree.insert("", "end", values=(6))
NewTree.grid(row=0,column=0)
def SumAllCosts():
for i in NewTree.get_children():
a = NewTree.item(i,"values")[0]
if len(a)==0:
NewTree.delete(i)
SumPreCosts=0.0
for child in NewTree.get_children():
PreCost=round(float(NewTree.item(child,"values")[0]),2)
SumPreCosts += PreCost
TotalEntry.delete(0,"end")
TotalEntry.insert(0,round(SumPreCosts,2))
Sum=Button(myApp,text=" Sum ",command=SumAllCosts)
Sum.grid(row=0,column=2, sticky="w",pady=5)
myApp.mainloop()

If you print type(NewTree.item(i, "values")) and repr(NewTree.item(i, "values")), you can see that this returns
<class 'tuple'> ('2',)
<class 'str'> ''
<class 'tuple'> ('6',)
As you can see, for the 2 and 6 entry, this returns a tuple so you can do NewTree.item(i, "values")[0] to get the first value. However, the empty item is returned as an empty string, so NewTree.item(i, "values")[0] gives the error you describe.
You can change that part of the code to check if NewTree.item(i, "values") is not empty:
for i in NewTree.get_children():
if not NewTree.item(i, "values"):
NewTree.delete(i)
