Error When Configuring Tkinter Widget: 'Nonetype' Object Has No Attribute

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()

Error when configuring tkinter widget: 'NoneType' object has no attribute

NoneType object has no attribute ... means that you have an object that is None, and you're trying to use an attribute of that object.

In your case you're doing q.get(...), so q must be None. Since q is the result of calling nse.get_quote(...), that function must have the possibility of returning None. You'll need to adjust your code to account for that possibility, such as checking the result before trying to use it:

q = nse.get_quote(stock)
if q is not None:
    print ...

The root of the problem is likely in how you're reading the file. stock will include the newline, so you should strip that off before calling nse.get_quote:

q = nse.get_quote(stock.strip())

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.

AttributeError: 'NoneType' object has no attribute 'config'

The issue seems to in this can be traced backed to this line

buLogin = ttk.Button(frame,text="Login").grid(row=2,column=1)

i think the .grid() is not returning anything. can you try like this

buLogin = ttk.Button(frame,text="Login")
buLogin.grid(row=2,column=1)

And ideally you should change all the usage of grid() like this.

This should work, I havn't tested this yet. please let us know the result.

Happy coding :)

Why is Tkinter widget stored as None? (AttributeError: 'NoneType' object ...)(TypeError: 'NoneType' object ...)

widget is stored as None because geometry manager methods grid, pack, place return None, and thus they should be called on a separate line than the line that creates an instance of the widget as in:

widget = ...
widget.grid(..)

or:

widget = ...
widget.pack(..)

or:

widget = ...
widget.place(..)

---

And for the 2nd code snippet in the question specifically:

widget = tkinter.Button(...).pack(...)

should be separated to two lines as:

widget = tkinter.Button(...)
widget.pack(...)

PYTHON Nonetype object has no attribute .get() tkinter

The .place() method does not return a reference to the object. It is not a "chaining method". It simply alters the place and returns None, as is described in the documentation.

You should call the .place() method after calling the constructor (and setting a reference to the Entry), like:

userINP = Entry(root, width=25, bg ="White")
userINP.place(x=120,y=100)
userINP.get(...)

Python - tkinter 'AttributeError: 'NoneType' object has no attribute 'xview''

The problem is that grid returns None, not self.

So, when you do this:

decimalView = ttk.Entry(mainframe, state = DISABLED, background = "gray99", width = 30, textvariable = decimal).grid(column = 2, row = 2, sticky = W)

… you're setting decimalView to None. Which is why the error message tells you that it can't find an xview attribute on None.

And this isn't some weird quirk of Tkinter; almost every method in Python that mutates an object in any way returns None (or, sometimes, some other useful value—but never self), from list.sort to file.write.

Just write it on two lines: construct the Entry and assign it to decimalView, and then grid it.

Besides the minor benefit of having working code, you'll also have more readable code, that doesn't scroll off the right side of the screen on StackOverflow or most text editors.

NoneType' object has no attribute 'config'

pButton = Button(root, text="Play", command="playButton").grid(row=1)

Here you are creating an object of type Button, but you are immediately calling the grid method over it, which returns None. Thus, pButton gets assigned None, and that's why the next row fails.

You should do instead:

pButton = Button(root, text="Play", command="playButton")
pButton.grid(row=1)
pButton.config(image=PlayUp)

i.e. first you create the button and assign it to pButton, then you do stuff over it.
