带有 tkinter 的 GUI

Question

Getting started with GUI with Tkinter but it's not running

from tkinter import *

root = Tk()
thelabel = Label(root, "hello")
thelabel.pack()
root.mainloop()

I'm getting the following error:

Traceback (most recent call last):
  File "guidemo1.py", line 4, in <module>
    thelabel = Label(root, "hello")
  File "C:\Users\Admin\AppData\Local\Programs\Python\Python37-32\lib\tkinter\__init__.py", line 2766, 

in __init__
    Widget.__init__(self, master, 'label', cnf, kw)
  File "C:\Users\Admin\AppData\Local\Programs\Python\Python37-32\lib\tkinter\__init__.py", line 2295, in __init__
    classes = [(k, v) for k, v in cnf.items() if isinstance(k, type)]

AttributeError: 'str' object has no attribute 'items'

Answer 1

The documentation for Label says that the second argument is a list not a string. You could skip this second positional argument and use the keyword argument text :

thelabel = Label(root, text = "hello")

Answer 2

Instead of

thelabel = Label(root, "hello")

You should have used the "text" argument for Labels

theLabel = Label(root, text="hello")

Answer 3

the Label is not done correctly, the code must be:

import tkinter

root = tk.Tk()
thelabel = tkinter.Label(root, text="hello")
thelabel.pack()
root.mainloop()

also, you can use from tkinter import* as well, i just do it like this, if you do so, also change the label to Label(root, text="hello") and root to just Tk()
