Create GUI with Python Using Tkinter – Step-by-Step Guide!
Want to build a graphical user interface (GUI) with Python? In this video, we’ll show you how to create a GUI using Tkinter, Python’s built-in library for creating simple and effective GUI applications. Follow along with our step-by-step guide and examples to get started with Tkinter!
Learn:
Install Tkinter
sudo apt install python3-tk
Example 1: Just a Window
Create a file called window.py:
import tkinter as tk
Create a window
window = tk.Tk()
window.title("My Window")
Keep the window open
window.mainloop()
Run with:
python3 window.py
Example 2: Window + Label
Create label.py:
import tkinter as tk
window = tk.Tk()
window.title("Hello App")
Add text to the window
label = tk.Label(window, text="Hello Ubuntu!")
label.pack()
window.mainloop()
Example 3: Add a Button
Create button.py:
import tkinter as tk
window = tk.Tk()
window.title("Button App")
Add text
label = tk.Label(window, text="Click the button!")
label.pack()
Add button
button = tk.Button(window, text="Click Me!")
button.pack()
window.mainloop()
Example 4: Button That Does Something
Create working_button.py:
import tkinter as tk
def say_hello():
label.config(text="Hello Ubuntu User!")
window = tk.Tk()
window.title("Working Button")
label = tk.Label(window, text="Waiting...")
label.pack()
Button that calls say_hello function
button = tk.Button(window, text="Press Me", command=say_hello)
button.pack()
window.mainloop()
Example 5: Text Input
Create input.py:
import tkinter as tk
def show_name():
name = entry.get()
label.config(text=f"Hello {name}!")
window = tk.Tk()
window.title("Name App")
label = tk.Label(window, text="Enter your name:")
label.pack()
Text input box
entry = tk.Entry(window)
entry.pack()
button = tk.Button(window, text="Submit", command=show_name)
button.pack()
window.mainloop()
What Each Part Does:
import tkinter as tk: Loads the GUI toolkit.
tk.Tk(): Creates the main window.
.title(): Sets the window title.
Label: Shows text.
Button: Makes a clickable button.
Entry: Text input box.
.pack(): Puts the widget in the window.
.mainloop(): Keeps the window open.
