Float is required (in Tkinter) - python

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.
When trying to calculate the hypotenuse of a triangle with Vel_in_y as the opposing side.
import tkinter
import math
window= tkinter.Tk()
frame = tkinter.Frame(window)
frame.pack()
Velocidad_in =tkinter.IntVar()
Angulo_desp = tkinter.IntVar()
Altura_max = tkinter.IntVar()
Alcan = tkinter.IntVar()
Temp = tkinter.IntVar()
Vel_in_y= tkinter.IntVar()
Vel_in_x= tkinter.IntVar()
var = [Velocidad_in,Angulo_desp ,Altura_max,Alcan,Temp,Vel_in_y,Vel_in_x]
opciones_de_Vel = ['Velocidad Inicial en X','Velocidad Inicial en Y','Modulo de Velocidad']
def Velocidad_Inicial(root):
for (tipo,var) in ((' La Velocidad Inicial en X',Vel_in_x),(' La Velocidad Inicial en Y',Vel_in_y),(' El Modulo de Velocidad',Velocidad_in)):
label = tkinter.Label(frame,text= 'Inserte '+ tipo)
label.pack()
entry= tkinter.Entry(frame,textvariable = var)
entry.pack()
def Angulo_Despegue(root):
label = tkinter.Label(frame,text='Inserte el Angulo de despegue')
label.pack()
entry= tkinter.Entry(frame,textvariable = Angulo_desp)
entry.pack()
def Altura_Maxima(root):
label = tkinter.Label(frame,text='Inserte la Altura Maxima')
label.pack()
entry= tkinter.Entry(frame,textvariable = Altura_max)
entry.pack()
def Alcance(root):
label = tkinter.Label(frame,text='Inserte el Alcance')
label.pack()
entry= tkinter.Entry(frame,textvariable = Alcan)
entry.pack()
def Tiempo(root):
label = tkinter.Label(frame,text='Inserte el Tiempo')
label.pack()
entry= tkinter.Entry(frame,textvariable = Temp)
entry.pack()
def calcular_modulo(root):
modulo = Vel_in_y* math.sin(Angulo_desp)
label = tkinter.Label(frame,textvariable=modulo)
label.pack()
if modulo == 0:
modulo = math.sqrt(Vel_in_x**2+ Vel_in_y**2)
label = tkinter.Label(frame,textvariable=modulo)
label.pack()
button = tkinter.Button(frame,text='respuesta' ,command = lambda: calcular_modulo(window))
button.pack()
menubar = tkinter.Menu(window)
option_menu =tkinter.Menu(menubar)
option_menu.add_command(label= 'Velocidad Inicial',command=lambda:Velocidad_Inicial(window))
option_menu.add_command(label= 'Angulo de Despegue',command=lambda:Angulo_Despegue(window))
option_menu.add_command(label= 'Altura Maxima',command=lambda:Altura_Maxima(window))
option_menu.add_command(label= 'Alcance',command=lambda:Alcance(window))
option_menu.add_command(label= 'Tiempo', command=lambda:Tiempo(window))
menubar.add_cascade(label= 'Tipo de Variable',menu=option_menu)
window.config(menu=menubar)
window.mainloop()
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()

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)

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()

Problems when positioning buttons with tkinter

I'm having trouble creating buttons in tkinter, I've tried doing it in different ways, but I haven't reached the solution.
It turns out that one of the requirements that they have made me when making this calculator is to create three text boxes and eleven buttons, so when I create the positioning of the boxes and I want to place the buttons they do nothing, if I try to tell them to position in column 3, row 4 is not positioned.
Image of the code output
This is the code, if you see something wrong that I have not been able to see and that is the cause of such an error, I would appreciate it
from tkinter import *
#instancia de calculadora
calculadora = Tk()
#Nombre de la ventana grafica
calculadora.title("Practica calculadora con tkinter")
#tamano de la ventana
calculadora.geometry("600x750")
#color personalizado de la ventana
calculadora.configure(bg="black")
firtDisplay = Entry(calculadora, state="readonly", width=25).place(x=0, y=5)
secondDisplay = Entry(calculadora, state="readonly", width=25).place(x=300, y=5)
thirdDisplay = Entry(calculadora, state="readonly", width=25).place(x=149, y=40)
#Botones
Button(calculadora, text="7", width=15).grid(row=5, column=3)
Button(calculadora, text="8", width=15)
Button(calculadora, text="9", width=15)

Please help would be very good, thank you ...
I think you must first of all use only one type of geometry management, and then keep it simplest, I've made some changes to show how to use grid manager with some loop.
from tkinter import *

r = 0
c = 0
for i in range(0,4):
if i < 3:
Entry(calculadora, state="readonly", width=15).grid(row=r, column=c)
else:
Checkbutton(calculadora, width=15, text="/").grid(row=r, column=c)
c +=1
array = (("7","8","9","x"),("4","5","6","-"),("1","2","3","+"))
r = 1
c = 0
for items in array:
for i in items:
index = items.index(i)
if index < 3:
Button(calculadora, text=i, width=15).grid(row=r, column=c)
else:
Checkbutton(calculadora, width=15, text=i).grid(row=r, column=c)
c +=1
r +=1
c = 0
calculadora.mainloop()
You souldn't mix .pack(), .grid(), and .place() in the same master window.

How to constantly update a variable (using a spinbox with tkinter)?

I have in my program two spinboxes, created with tkinter. I want the variables chosen by the user to be added to a list, so I can use those values later in the program. The problem I'm currently having is that the values are stored just once in the list, and I don't manage to update them, despite all of the things I tried. To be clear, I just want two values in the list, so when the user select another number, it will replace the proper value stored in the list.
Here is the code I wrote :
from tkinter import *
windowTk = Tk()
pwMain = PanedWindow(windowTk, orient=VERTICAL)
pwTop = PanedWindow(pwMain, orient=HORIZONTAL)
def configTables() :
sLine = Spinbox(pwTop, from_=0, to=15)
pwTop.add( Label(pwTop, text = "Combien y a-t-il de lignes de table ?") )
pwTop.add( sLine )
sColumn = Spinbox(pwTop, from_=0, to=15)
pwTop.add( Label(pwTop, text = "Combien y a-t-il de colonnes de tables ?") )
pwTop.add( sColumn )
pwTop.pack()
pwMain.pack()
global coordTables
coordTables = []
coordTables.append( int(sLine.get()) )
coordTables.append( int(sColumn.get()) )
return coordTables
print( configTables() )
windowTk.mainloop()
I hope my request is understandable, so you can help me.
Thank you

UPDATE : I tried the following code, and it works, but nothing appears in the window (tkinter's window remains white).
from tkinter import *
windowTk = Tk()
pwMain = PanedWindow(windowTk, orient=VERTICAL)
pwTop = PanedWindow(pwMain, orient=HORIZONTAL)
lines = IntVar(windowTk, value=0)
columns = IntVar(windowTk, value=0)
def configTables() :
sLine = Spinbox(pwTop, from_=0, to=15, textvariable=lines)
pwTop.add( Label(pwTop, text = "Combien y a-t-il de lignes de tables ?") )
pwTop.add( sLine )
sColumn = Spinbox(pwTop, from_=0, to=15, textvariable=columns)
pwTop.add( Label(pwTop, text = "Combien y a-t-il de colonnes de tables ?") )
pwTop.add( sColumn )
pwTop.pack()
pwMain.pack()
numberLines = lines.get()
numberColumns = columns.get()
print( numberLines, numberColumns )
windowTk.mainloop()
I know it will print just once the values and that's what I want it to do.
Can you help me ? I think it's very simple, but I don't find where's the problem.
You can use IntVar to connect the spin boxes to Python variables. I have extended your program with an example. It adds a button to print the current value of the spin boxes:
from tkinter import *
windowTk = Tk()
pwMain = PanedWindow(windowTk, orient=VERTICAL)
pwTop = PanedWindow(pwMain, orient=HORIZONTAL)
lignes = IntVar(windowTk, value=0)
colonnes = IntVar(windowTk, value=0)
def print_vars():
print(lignes.get(), colonnes.get())
def configTables() :
sLine = Spinbox(pwTop, from_=0, to=15, textvariable=lignes)
pwTop.add( Label(pwTop, text = "Combien y a-t-il de lignes de table ?") )
pwTop.add( sLine )
sColumn = Spinbox(pwTop, from_=0, to=15, textvariable=colonnes)
pwTop.add( Label(pwTop, text = "Combien y a-t-il de colonnes de tables ?") )
pwTop.add( sColumn )
pwTop.pack()
b = Button(pwMain, text='print', command=print_vars)
b.pack(side=BOTTOM)
pwMain.pack()
global coordTables
coordTables = []
coordTables.append( int(sLine.get()) )
coordTables.append( int(sColumn.get()) )
return coordTables
print( configTables() )
windowTk.mainloop()
Note, I have not removed things which are no longer necessary, like coordTables variable and the return statement.
this is what you would want to do, I believe.
I suggest you an object oriented approach.
Tkinter has IntVar() and other variables very powerfull.
import tkinter as tk
class App(tk.Frame):
def __init__(self,):
super().__init__()
self.master.title("Hello World")
self.lines = tk.IntVar()
self.columns = tk.IntVar()
self.coordTables = []
self.init_ui()
def init_ui(self):
self.pack(fill=tk.BOTH, expand=1,)
f = tk.Frame()
tk.Label(f, text = "Combien y a-t-il de lignes de tables ?").pack()
tk.Spinbox(f, from_=0, to=15, textvariable= self.lines).pack()
tk.Label(f, text = "Combien y a-t-il de colonnes de tables ?").pack()
tk.Spinbox(f, from_=0, to=15, textvariable= self.columns).pack()
w = tk.Frame()
tk.Button(w, text="Print", command=self.on_callback).pack()
tk.Button(w, text="Reset", command=self.on_reset).pack()
tk.Button(w, text="Close", command=self.on_close).pack()
f.pack(side=tk.LEFT, fill=tk.BOTH, expand=0)
w.pack(side=tk.RIGHT, fill=tk.BOTH, expand=0)
def on_callback(self,):
args = (self.lines.get(),self.columns.get())
self.coordTables.append(args)
print ("Numers of coords: {0}".format(len(self.coordTables)))
for e,i in self.coordTables:
print(e,i)
def on_reset(self):
self.lines.set(0)
self.columns.set(0)
self.coordTables = []
def on_close(self):
self.master.destroy()
if name == 'main':
app = App()

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:

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

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.

tkinter labels dont show

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()
