Creating graphical user interfaces in Python often involves the use of the Tkinter library. Tkinter makes it easy to design simple to complex interfaces for various applications. One of the most vital elements of any GUI is the button. Buttons provide users with a way to interact with the application and trigger specific actions.

Creating Buttons in Tkinter

In this code snippet:

We first import the Tkinter library as tk.

Create the main application window with root = tk.Tk().

Then, define a button using tk.Button(). The text parameter specifies the label displayed on the button, and the command parameter assigns a callback function that triggers when the button is clicked.

Finally, we use the pack() method to place the button on the application window and initiate the main loop with mainloop().
