GUI/Using Tkinter

I'm using python 3.7, and I did from Tkinter import *, and when I wrote my code an pressed "Run", a screen popped up and shut down within half a second. This happens every time I press "Run". Can somebody please help me?

I'm completely new to Python, but ran into the same problem. From other souces I managed to add the following to get tkinter window to stay open: 

# Bit of code to keep tkinter window open in Pycharm
root = Tk()
root.mainloop()

Don't ask me how it works though. If someone can explain, or improve on this, I'd be grateful.

You will always require require the use of ".mainloop()" in any creation of a window within Tkinter, there's not really an alternative I know of. It is a function that cycles the window until it is interrupted with a command such as quit. The mainloop function always needs to be declared at the end of whatever is within the given window you have created or else it'll cut off anything that you tell the Python console to run within the window.

The variable you create "root" is what you will reference anything to, such as Labels, Entry windows etc as that is what is called the "master". The master tells the widget (such as a Label) which window to go to, it's like a GPS location, but only for Tkinter widgets. Frames come into play with the "master" but that's much more advanced, but keep it in mind as it's something to explore later on within Tkinter. 

Anyway, here are two examples to give you a bit of clarity of what I have explained, if you run them in your Python IDE of choice you'll be able to see the use of Mainloop, also I added a few bonus features to the window for you being completely new to Python, hope this clears some stuff up for you! :)

This is how it should look because Mainloop is at the end of everything declared for the window-

import tkinter
from tkinter import *
##Import of Tkinter module

window = Tk()
##Creates the window from the imported Tkinter module
window.geometry("600x400")
##Creates the size of the window
window.title("Test :)")
##Adds a title to the Windows GUI for the window

window.mainloop()
##Loops the window to prevent the window from just "flashing once"

This is how it shouldn't look, as Mainloop is placed in the middle of everything being declared for the window-

import tkinter
from tkinter import *
##Import of Tkinter module

window = Tk()
##Creates the window from the imported Tkinter module
window.mainloop()
##Loops the window to prevent the window from just "flashing once"
window.geometry("600x400")
##Creates the size of the window
window.title("Test :)")
##Adds a title to the Windows GUI for the window

Thank you so very much for that. Great explanation.

No problem! Also always remember to add the two brackets to the end of Mainloop like so- "root.mainloop()" as Mainloop is a function, not a command or else your program won't run but the Python IDE won't detect it as a fault in the console.

Try the simple one on windows

import _tkinter
from Tkinter import *
root = Tk()
w = Label(root, text="Hello World")
w.pack()

root.mainloop()

In Debian it work

sudo apt install python3-tk

Pycharm can not import tkinter library in windows Python3.7,is like pycharm can not find the library.

Hi, could you please provide an example? Please feel free to create a ticket in our bug tracker directly: https://youtrack.jetbrains.com/issues/PY

This is nuts. I can't find a way to get tkinter to work on pycharm on linux. I also can't get tkinter to work with Eric. I'm going to have to abandon creating a linux distribution of my program.

Make sure you check the right import for your version of Python.  In 2.7 it's Tkinter and 3.x it's tkinter.

i followed what Iamsnaks wrote above and typed in the entire set of commands word for word. Now the issue i have is that it says that tkinter is not a module. I followed the rule of typing in lower case as I am using windows. My python version is 3.7. 

Not sure why this is not working. Any help greatly appreciated. 

Incidentally I stumbled on a glinted script. First I tried it on Ubuntu 22 then it failed so I tried the terminal in pycharm without on importing it worked perfectly. Then I just was determined to work on Ubuntu so after googling I found that with brew installation it works. I tried with pip but it kept showing errors tkinter not a module error.
