Labels not defined in tkinter app

module 'tkinter' has no attribute 'label'
tkinter title
name 'tkinter' is not defined
how to set height and width of label in tkinter
nameerror: name 'label' is not defined kivy

I'm trying to make a basic window with the text "t" inside using Tkinter, however when running the code the shell spits out "NameError: name 'Label' is not defined". I'm running Python 3.5.2.

I followed the tutorials but the problem is in the label = Label(root, text="test") line.

import tkinter

root = tkinter.Tk()
sheight = root.winfo_screenheight()
swidth = root.winfo_screenwidth()
root.minsize(width=swidth, height=sheight)
root.maxsize(width=swidth, height=sheight)

label = Label(root, text="test")
label1.pack()

root = mainloop()

Is the label function different in 3.5.2?


You never imported the Label class. Try tkinter.Label

Check the import statements for those tutorials

Maybe they imply from tkinter import *

GUI Programming with Python: Labels in Tkinter, A Label is a Tkinter Widget class, which is used to display text or an image. The label is a widget that the user just views but not interact with.

root.maxsize(width=swidth, height=sheight)

label = tkinter.Label(root, text="test")

root = tkinter.mainloop() # <- prob need to fix this as well.

Because you didn't do from tkinter import * you need to invoke the Label from the tkinter module.

Alternatively you can do:

from tkinter import *
...
label = Label(root, text="test")

Python label is not defined, tkinter NameErrorFrame is not defined file = Menu(menu) file.add_command(​label="Exit", command=self.client_exit) app = Window(root) root.mainloop() Because you didn't do from tkinter import * you need to invoke the Label from the tkinter module. Alternatively you can do: from tkinter import * label = Label(root, text="test")


stumbled across the same Problem. Most beginners guides seem to mess up here. I had to use a second line in the configuration:

!/usr/bin/python3

import tkinter from tkinter import *

...

tkinter NameErrorFrame is not defined, If you do not specify a size for the label widget, it will be made just large enough to fit the text.
