I am still new to python, I am trying to create an inventory management program for my work. I am stuck in the part where the user has to return some items back to stock after it was sent but returned by the customer. Basically I generate a list with the order name and beside each label there is a check box. The user has to tick the box beside the item that was returned. The problem is I cannot seem to retrieve the values of each box.
This is my code:
def send(var,d):
x=[]
for i in range(0,len(var)):
x.append(var[i].get())
print(x)
def create_list(d,p,s,q,w):
import tkinter as tk
master4 = tk.Tk()
var={}
var2=[]
tk.Label(master4, text='Description').grid(row=0,column=0)
tk.Label(master4, text='Part number').grid(row=0,column=1)
tk.Label(master4, text='Serial number').grid(row=0,column=2)
tk.Label(master4, text='Well').grid(row=0,column=3)
for i in range(0,len(p)):
tk.Label(master4, text=str(d[i])).grid(row=i+1,column=0)
tk.Label(master4, text=str(p[i])).grid(row=i+1,column=1)
tk.Label(master4, text=str(s[i])).grid(row=i+1,column=2)
tk.Label(master4, text=w).grid(row=i+1,column=3)
var[i]=tk.IntVar()
tk.Checkbutton(master4, text="", variable=var[i]).grid(row=i+1,
column=4)
tk.Button(master4, text='Next',
command=lambda:returns.send(var,0)).grid(row=i+2,column=2)
It is part of a class called returns. The result is always a list of zeroes no matter which boxes I tick. The curious thing is that I wrote this exact code in a separate stand alone module and it worked like a charm.
Here's the one that worked:
def sends(v):
x=[]
for i in range(0,len(v)):
x.append(v[i].get())
print(x)
import tkinter as tk
master = tk.Tk()
var={}
tk.Label(master, text='Description').grid(row=0,column=0)
tk.Label(master, text='Part number').grid(row=0,column=1)
tk.Label(master, text='Serial number').grid(row=0,column=2)
tk.Label(master, text='Well').grid(row=0,column=3)
for i in range(0,3):
tk.Label(master, text='Ali').grid(row=i+1,column=0)
tk.Label(master, text='Ali').grid(row=i+1,column=1)
tk.Label(master, text='ALI').grid(row=i+1,column=2)
tk.Label(master, text='Well').grid(row=i+1,column=3)
var[i]=tk.IntVar()
tk.Checkbutton(master, text="", variable=var[i]).grid(row=i+1,
column=4)
tk.Button(master, text='Next',
command=lambda:sends(var)).grid(row=i+2,column=2)
tk.Button(master, text='Cancel',
command=master.destroy).grid(row=i+2,
column=1)
master.mainloop()
Why is one working the the other not? Does it have to do with the fact that the first one is part of a class and not just a function? I would appreciate any help.
