Python - How to assign numbers from Entry Widgets to list and sum them?
I have created some entry widgets for user to input points for different teams. I would like to know, how is it possible assign them to particular list and sum those points to print the result...
My code below showed what have I tried, but it doesn't work and I receive an error:
ValueError: invalid literal for int() with base 10: ''
Also, if I will remove sum functions, numbers does not appear in lists. Can anyone explain me how to solve this problem? My code:
from tkinter import *
import tkinter.ttk as ttk
class CollegeApp(Tk):
def __init__(self):
Tk.__init__(self)
container = ttk.Frame(self)
container.pack(side="top", fill="both", expand=True)
self.frames = {}
for F in (StartPage, counterPage):
frame = F(container, self)
self.frames[F] = frame
frame.grid(row=0, column=0, sticky="nsew")
self.show_frame(StartPage)
self.lift()
def show_frame(self, cont):
frame = self.frames[cont]
frame.tkraise()
class StartPage(ttk.Frame):
def __init__(self, parent, controller):
self.controller = controller
ttk.Frame.__init__(self, parent)
self.startMenu()
def startMenu(self):

font=('Arial', 25))
heading.grid(row=0, column=0, columnspan=2, padx=240, pady=40)
start_Btn = Button(self, text="START", font="Arial 16", width=8, height=2,

AS Your code is written, it do this: When it runs, it tries to get the values on the Entry objects, but there is nothing, so thats the error, you trying to convert to int a ''. The correct thing to do is this:
from tkinter import *
import tkinter.ttk as ttk
# global var
class CollegeApp(Tk):
def __init__(self):
Tk.__init__(self)
container = ttk.Frame(self)
container.pack(side="top", fill="both", expand=True)
self.frames = {}

frame = F(container, self)
self.frames[F] = frame
frame.grid(row=0, column=0, sticky="nsew")
self.show_frame(StartPage)

def show_frame(self, cont):

backBtn = Button(self, text="BACK", font="Arial 16", height=2, width=6,

# new function added: get_values()

pointsTeam3 = []
pointsTeam4 = []
app = CollegeApp()
app.geometry("800x500")
app.resizable(False, False)
app.title('Points Counter')
app.mainloop()
There are some things to change, you can see them with comments, you are using a list, so, for use the sum() function you need to .append() the value on the list, and every time that you call the function reset the list with pointsTeam1 = []
Use the self. to keep track of the attribute and get the value on the new function
get_values()
And for last thing, I made a function to check if the value inserted is a numeric value and convert it to int else return 0, you can raise an Error or show some message
I hope I was helpful
