How to Create Your First Python GUI Application

Creating your first Python GUI application is a great way to get started with GUI programming. Here is a simple example of How to Create Your First Python GUI Application using the Tkinter library:

Start by importing the Tkinter module:

import tkinter as tk

1	import tkinter as tk

Next, create a new Tkinter application by instantiating the Tk() class:

app = tk.Tk()

1	app = tk.Tk()

Set the title of the application window by calling the title() method on the application object:

app.title("My First GUI App")

1	app.title("My First GUI App")

Create a label widget by instantiating the Label() class and passing in the parent widget (the application window) and the text to display:

label = tk.Label(app, text="Hello, World!")

1	label = tk.Label(app, text="Hello, World!")

Use the grid() method to specify the position of the label widget within the application window:

label.grid(column=0, row=0)

1	label.grid(column=0, row=0)

Start the main event loop of the application by calling the mainloop() method on the application object:

app.mainloop()

1	app.mainloop()

Your complete code should look like this:

import tkinter as tk

app = tk.Tk()
app.title("My First GUI App")
label = tk.Label(app, text="Hello, World!")
label.grid(column=0, row=0)
app.mainloop()

import tkinter as tk

app = tk.Tk()

app.title("My First GUI App")

label = tk.Label(app, text="Hello, World!")

label.grid(column=0, row=0)

app.mainloop()

When you run this code, a window will appear with a simple label that says “Hello, World!”. This is a basic example of how to create a GUI application using Tkinter. You can experiment with different widgets and layouts to create more complex and functional applications.
