Tkinter: Attributeerror: Nonetype Object Has No Attribute ≪Attribute Name≫

Tkinter: AttributeError: NoneType object has no attribute attribute name

The grid, pack and place functions of the Entry object and of all other widgets returns None. In python when you do a().b(), the result of the expression is whatever b() returns, therefore Entry(...).grid(...) will return None.

You should split that on to two lines like this:

entryBox = Entry(root, width=60)
entryBox.grid(row=2, column=1, sticky=W)

That way you get your Entry reference stored in entryBox and it's laid out like you expect. This has a bonus side effect of making your layout easier to understand and maintain if you collect all of your grid and/or pack statements in blocks.

how to fix AttributeError: 'NoneType' object has no attribute 'get' for tkinter entry

it's entry.grid(...) return None

I think you want

    from tkinter import *

    root = Tk()

    a = Entry(root)
    a.grid(row = 0, column = 0)

    b = Button(root,text = 'CLICK', command= lambda: test()).grid(row = 2, column = 2)

    def test():
        print(a.get())


    root.mainloop()

NoneType object has no attribute to get (Tkinter)

If you are making an entry, be sure that it is not formatted like this:

r = Entry(root, width=15, bg="white").grid(row=0, column=1)

It should be like this to remove an AttributeError:

r = Entry(root, width=15, bg="white")
r.grid(row=0, column=1)

NoneType' object has no attribute 'get' while using Tkinter

I think you should call the grid method in a separate line,.
In your setup, CIK_Entry refers to the return value of .grid() method, which is None.

You want it to point to the tk.Entry return value.

CIK_Entry = Entry(window)
CIK_Entry.grid(row=1, column=1)

i am getting an AttributeError: 'NoneType' object has no attribute 'get' for my simple GUI program in python

The python shell makes it easy to experiment. Assuming the error is with enter I just pasted the first part of your code into the shell.

>>> import tkinter as tk
>>> from tkinter import *
>>> 
>>> root = tk.Tk()
>>> 
>>> enter = tk.Entry(root, width = 35, borderwidth = 5).grid(row = 0, column = 0, columnspan = 3, padx =10 , pady = 10)
>>> repr(enter)
'None'

Yep, its None. And that's typical. Object methods often don't return their own object. Its convenient for method chaining, but most objects are not designed for that. Just do what examples and tutorials show and put it on a separate line.

import tkinter as tk
from tkinter import *

root = tk.Tk()

enter = tk.Entry(root, width = 35, borderwidth = 5)
enter.grid(row = 0, column = 0, columnspan = 3, padx =10 , pady = 10)

def ButtonClick(number):

    print(number)
    current = enter.get()
    print(current)
    # enter.delete(0,END)
    # enter.insert(0, current + number)


button1 = tk.Button(root, text="1", bg="yellow",padx = 40, pady= 20, command=lambda: ButtonClick(1)).grid(row = 1, column = 0)
root.mainloop()

python tkinter error AttributeError: 'NoneType' object has no attribute 'insert'

You want to store the Text object in window, but you actually store the return value of pack, which is None. Splitting the line like this should fix the error:

window = Text(self, font=("Helvetica", 14))
window.pack()
