how to put the code in gui in python code example

Example 1: how to create a tkinter 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

Example 2: tkinter tutorial

# check this code first.
from tkinter import *

app = Tk()
# The title of the project
app.title("The title of the project")
# The size of the window
app.geometry("400x400")

# Defining a funtion
def c():
    # Label
    m = Label(app, text="Text")
    m.pack()


# Button
l = Button(app, text="The text of the Butoon", command=c)
# Packing the Button
l.pack()
app.mainloop()
# Quick Note : 
# When you put a command you should not use parentheses
# l = Button(app, text="The text of the Butoon", command=c)
# l = Button(app, text="The text of the Butoon", command=c())
