tk window doesn' t pop up-CodePudding

Hi I'm new to python and Tkinter. When I execute the code, nothing is happening an there isn't error. After less than one second,the code finish to process.

from tkinter import *
w1 = Tk()
w1.mainloop'

CodePudding user response：

First of all, you used

from tkinter import *

so tkinter.Tk isn't a thing, since tkinter isn't in the namespace, instead you must just do Tk

Also, tkinter.Tk is a class, and for it to work, needs to be instantiated. w1.mainLoop is a function, and needs to be called. Therefore, a working code should be

from tkinter import *
w1 = Tk()
w1.mainloop()

CodePudding user response：

I believe you already fixed your typo w1.mainloop' to w1.mainloop(). I want to recommend using import tkinter as tk, so you don't overwrite you namespace.

Then your code could look like this:

import tkinter as tk

w1 = tk.Tk()
w1.mainloop()
