tkinter labels dont show - python

So I got the assignment to make a small Bingo App (Windows btw) after I followed a few webinars on Tkinter GUI and some Googling.
I have made successfull little apps that worked correctly, but this time I try to make it with knowledge I think I have.
Anyway, in that Bingo app, I want 50 labels that represent 50 numbers of the Bingo card, 5 rows of 10 numbers.
I know how to align them, but they need to show up first.
Can you look at my code and assess what I do wrong?
Ignore the many Dutch comments :)

You need to learn about data structures, like list.
You had root.mainloop() early on in the code. That starts a loop. Nothing after that is executed until the window is closed, which means it has to be at the end.
Choose one geometry manager. You can't use both grid() and pack() in the same parent widget, much less on the same child widget.
You had some typos, like label7 = instead of label17 =, and label28.Label instead of label28 = Label. Most of these would never have happened if you had used a list.
Obviously, 50 labels won't fit in a single column in a window of that size. You've got some decisions ahead of you involving window size, label placement, possible scrollbar, and so on.
The resulting code taking into account all these points (except the last) is shown below.
from tkinter import *
root = Tk()
root.wm_title("Bingo Python")
root.wm_maxsize("800","600")
root.wm_minsize("800","600")
labels = [Label(root, text=i) for i in range(1, 51)]
for label in labels:
label.pack()
root.mainloop()

I import another page in tkinter but it is empty

as you can see when importing this window through the menu, it is empty:

Python: calling function inside if statement from another File

I have an error in my program: "Taula_G3110 ()
NameError: name 'Taula_G3110' is not defined"
My question is:
I want to call a function that is inside an IF loop.This function is in another file. I have tried everything with imports:
"from Kleben_Tabelle import Taula_G3110, Taula_G3111.
import Kleben_Tabelle ", but there is no way.
Does anyone have an idea what I'm doing wrong?
Code:
from tkinter import *
from PIL import Image, ImageTk
from tkinter import ttk
from tkinter import messagebox
#from Kleben_Tabelle import *
import serial
import time
import PIL.Image
import Kleben_Tabelle
root = Tk()
root.geometry("1000x600")
# root.resizable (False,False)
root.title("Combobox")
arduino = serial.Serial("COM7", 9600)
time.sleep(0.1) # reducir el uso de la CPU.Prueba con diferentes valores (0.01 a 0.1)
def cambiar():
mes = combo.get()
if mes == "G3110":
label_resultat.configure(text=txt)
Taula_G3110()
if mes == "G3111":
label_resultat.configure(text=txt2)
Taula_G3111()
if mes == "G3112":
messagebox.showinfo("Mes", "Marzo")
def apagarLED():
arduino.write(b'4')
time.sleep(1)
def cerrarInterfaz():
# cerrar comunicación Serial
global raiz
arduino.close()
# cerrar ventana
root.destroy()
image = Image.open ('Edifici_Knauer_blau.png')
photo_image = ImageTk.PhotoImage(image)
label = Label(root, image=photo_image)
label.pack()
frame_resultat = Frame(root, width=400, height=100, relief="flat", highlightbackground="blue", highlightthickness=1)
frame_resultat.place(x=250, y=200)
label_resultat = Label(root, text="", bg="yellow", borderwidth=0, relief="groove", width=20, height=2, justify='left',
highlightbackground="blue", highlightthickness=1)
label_resultat.place(x=80, y=200)
etiqueta = Label(root, text="Zelle: Kleben")
etiqueta.place(x=100, y=40)
combo = ttk.Combobox(root, state="readonly")
combo.place(x=100, y=70)

and this ist my other File with this Module-Function:(File: Kleben_Tabelle.py)
def Taula_G3110():
arduino.write(bytes(b'T'))

arbol.heading("Regal",text="Regal")
arbol.place(x=100,y=70)

In order to call a function in a module that you've imported, you need to reference the module and function like so:
import Kleben_Tabelle
...
def cambiar():
mes = combo.get()
if mes == "G3110":
label_resultat.configure(text=txt)
Kleben_Tabelle.Taula_G3110()

How to sum a Treeview's values in Tkinter

I'm developing a GUI where the idea is to add some values to a treeview (as a billing system) and then get the result or sum of all items' prices.
The button "Agregar" (Add in English) get the Entries' data and add them to the treevew; one of them if the amount of money to pay.
Now what I want, and haven't been able to get, is the sum of the values given in the treeview to be shown in the field or entry which is below the treeview when "Generar" (Generate in English) button is pressed.
Next, the code I got:

The code is not finished, that's why it has so much info. But next function is what give me the values I need to be sum:

for child in children:
i = tree.item(child, 'values')[2]#OBTIENE LOS VALORES DE LOS ITEMS
print i
By the way, this file is called by another (home.py) to interact with it.
If anyone could give me a hand this problem, you'll save a life. Thanks for your time, look on this, and anything you could answer. Sorry for my English if it is not good.

You have to convert string to float and then you can add to variable ie. total
def generar():
total = 0.0
for child in tree.get_children():
total += float(tree.item(child, 'values')[2])
print total
But you could add value even in agregar to get total with using button
# create global variables
total = 0.0
# or
total_var = DoubleVar()
def agregar():
# inform function to use external/global variable when you use `+=`
global total
v1 = cc.get()
v2 = None
v3 = cod.get()
v4 = desc.get()
v5 = valor.get()
total += v5
# or
total_var.set(total_var.get() + v5)
tree.insert('', 0, values=(v3,v4,v5))
Full working example
import Tkinter as tk
import ttk
# --- functions ---
def agregar(v3, v4, v5):
tree.insert('', 0, values=(v3,v4,v5))
def generar():
total = 0.0
for child in tree.get_children():
total += float(tree.item(child, 'values')[2])
print total
result['text'] = 'Total: {}'.format(total)
# --- main ---
root = tk.Tk()
tree = ttk.Treeview(root, height=4, show="headings", columns=('col1','col2','col3'))
tree.pack()
tree.heading('col1', text='Código')
tree.heading('col2', text='Concepto')
tree.heading('col3', text='Valor')
add = tk.Button(root, text='Generar', command=generar)
add.pack()
result = tk.Label(root, text='Total: 0')
result.pack()
agregar("1", "AAA", 1.11)
agregar("2", "BBB", 2.22)
agregar("3", "CCC", 3.33)
root.mainloop()

The reason you are getting PY_VAR240 is because your code is trying to display an object instead of a value.
There is already an answer here that hints at the issue as well: Python Tkinter Treeview - Iterating 'get_children' output
Also here is how I get the values from a row:
rowItem = treeSomeTree.item(itemID)
itemDictionary = rowItem['values']
someVariable = itemDictionary[0]
Note the item id variable represents row item identifier which may or may not be a number and must be unique. The treeview .insert defaults to None (iid=None) if not specified.
By specifying the iid as an integer value as you inert rows you will always know which row you have (or need to get) to summarize.

Float is required (in Tkinter)

I have a problem that i still cant solve, specifically involving tkinter.
Eventhough some parts of the code are written in spanish I hope its not a problem.

If you spot an error,Ill apreciate all feedback!
BTW when I run this code I get an error saying :
TypeError: a float is required

modulo = Vel_in_y* math.sin(Angulo_desp.get())
math.sin has no idea what to do with an IntVar ... you must get the value
the same applies everywhere else you are trying to access the value of the variables

I don't understand why you use IntVal instead int .
You need to convert IntVal type to int type by use the get function .
Here is your code , it was fixed :
def calcular_modulo(root):
modulo = Vel_in_y.get()* math.sin(Angulo_desp.get())
label = tkinter.Label(frame,textvariable=modulo)
label.pack()
if modulo == 0:
modulo = math.sqrt(Vel_in_x.get()**2+ Vel_in_y.get()**2)
label = tkinter.Label(frame,textvariable=modulo)
label.pack()

Tkinter - setting string variables and getting entry values when looping

My goal is to be able to pass string variables to two different entries for user validation and return the user modified values. The code works fine if it is executed a single time; however, when looped, it only performs correctly during the first iteration of the loop. During subsequent iterations the string variables for the entries are blank.
I have experimented with update_idletasks() and time-sleep without luck. I am running Python 2.4 on Windows XP.
# -*- coding: cp1252 -*-
import Tkinter
def retrieve_text():
app_win.quit()
for item in range(3):
numero_dossier = item+1
version_dossier = item+2
app_win = Tkinter.Tk()
l = Tkinter.Label(app_win, text="Veuillez valider les informations suivantes et les corriger au besoin :")
l.grid(row=0, column=0, columnspan=2)
l.pack()
v1 = Tkinter.StringVar()
v1.set(numero_dossier)
l1 = Tkinter.Label(app_win, text="Numéro de dossier:", anchor='w', justify='left')
e1 = Tkinter.Entry(app_win, textvariable=v1)
l1.pack()
e1.pack()
v2 = Tkinter.StringVar()
v2.set(version_dossier)
l2 = Tkinter.Label(app_win, text="Version du dossier:", anchor='w', justify='left')
e2 = Tkinter.Entry(app_win, textvariable=v2)
l2.pack()
e2.pack()
app_button = Tkinter.Button(app_win,text="OK",command=retrieve_text)
app_button.pack()
app_win.mainloop()
app_win.withdraw()
numero_dossier = e1.get().strip()
version_dossier = e2.get().strip()
print numero_dossier, version_dossier

This is fundamentally broken:
for item in range(3):
...
app_win = Tkinter.Tk()
Tkinter is simply not designed to work this way. Your program should only ever create a single instance of the class Tk, and you should call mainloop exactly once.

There is no rationale in the question on why the widgets are being constructed multiple times, so I will take that as a mistake. Also, the name app_win for an Tkinter.Tk instance might be fooling you. Instantiating Tkinter.Tk starts a tcl interpreter, and then loads tk which as a "bonus" gives you a window.
The more sensible approach is creating the widgets only once, and then doing the multiple validations you are after. Here is your code adjusted for this:
import Tkinter
NUM_D = range(3)
VER_D = range(3)
CURR_D = 0
def retrieve_and_update_text():
global CURR_D
num_d = e1.get().strip()
ver_d = e2.get().strip()
print num_d, ver_d
CURR_D = (CURR_D + 1) % 3
v1.set(NUM_D[CURR_D] + 1)
v2.set(VER_D[CURR_D] + 2)
root = Tkinter.Tk()
l = Tkinter.Label(root, text=u"Label")
l.grid(row=0, column=0, columnspan=2)
v1 = Tkinter.StringVar()
l1 = Tkinter.Label(root, text=u"Num", anchor='w', justify='left')
e1 = Tkinter.Entry(root, textvariable=v1)
l1.grid(row=1)
e1.grid(row=1, column=1)
v2 = Tkinter.StringVar()
l2 = Tkinter.Label(root, text=u"Ver", anchor='w', justify='left')
e2 = Tkinter.Entry(root, textvariable=v2)
l2.grid(row=2)
e2.grid(row=2, column=1)
app_button = Tkinter.Button(root, text=u"OK", command=retrieve_and_update_text)
app_button.grid(row=3)
v1.set(NUM_D[CURR_D] + 1)
v2.set(VER_D[CURR_D] + 2)
root.mainloop()

Thanks to Bryan Oakley and mmgp, I was able to come up with the following code that does what I need, even though I am breaking the mainloop rule as it gets called during each iteration of the loop. All comments are welcome. Thanks again!
# -*- coding: cp1252 -*-
import Tkinter
root = Tkinter.Tk()
def retrieve_and_update_text():
#global CURR_D
dossier = e1.get().strip()
version = e2.get().strip().upper()
print dossier, version
root.quit()
for item in range(3):
dossier = item+1
version = item+2
l = Tkinter.Label(root, text=u"Veuillez valider les informations suivantes et les corriger au besoin :")
l.grid(row=0, column=0, columnspan=2)
v1 = Tkinter.StringVar()
l1 = Tkinter.Label(root, text=u"Dossier :", anchor='w', justify='left')
e1 = Tkinter.Entry(root, textvariable=v1)
l1.grid(row=1)
e1.grid(row=1, column=1)
v2 = Tkinter.StringVar()
l2 = Tkinter.Label(root, text=u"Version :", anchor='w', justify='left')

root.mainloop()
if item == range(3)[-1]: # if last item
root.withdraw()
