from tkinter import *

mywindow = Tk() #Change the name for every window you make
mywindow.title("New Project") #This will be the window title
mywindow.geometry("780x640") #This will be the window size (str)
mywindow.minsize(540, 420) #This will be set a limit for the window's minimum size (int)
mywindow.configure(bg="blue") #This will be the background color

mywindow.mainloop() #You must add this at the end to show the window

#Creating Tkinter Window In Python:

from tkinter import *

new_window = Tk() #Create a window ; spaces should be denoted with underscores ; every window should have a different name
new_window.title("My Python Project") #Name of screen ; name should be the one which you already declared (new_window)
new_window.geometry("200x150") #Resizes the default window size
new_window.configure(bg = "red") #Gives color to the background

new_window.mainloop() #Shows the window on the screen

from tkinter import *

root = Tk()
root.title("Hello World")
message_label = Label(root, text="Hello World")
message_label.pack()

root.mainloop()

import tkinter
master = tkinter.Tk()
master.mainloop()

Installing Tkinter in Windows
Tkinter comes with the Python installer. We just need to install Python from www.python.org, and it comes along with the Python. We don't need to install it separately. Click on the checkbox of tcl/tk and IDE.
