How to check which Button was clicked in Tkinter ?

Are you using various buttons in your app, and you are being confused about which button is being pressed? Don't know how to get rid of this solution!! Don't worry, just go through the article. In this article, we will explain in detail the procedure to know which button was pressed in Tkinter.

Steps to Check which Button was clicked in Tkinter

Step 1: First, import the library Tkinter.

from tkinter import *

Step 2: Now, create a GUI app using Tkinter.

app = Tk()

Step 3: Then, create a function with one parameter, i.e., of the text you want to show when a button is clicked

def which_button(button_press):
   print (button_press)

Step 4: Further, create and display the first button by calling the which_button function you declared in step 3.

# Creating and displaying of button b1
b1 = Button(app, text="Apple", command=lambda: which_button("Apple"))
b1.grid(padx=10, pady=10)

Step 5: Moreover, create and display the second button by calling the which_button function you declared in step 3.

# Creating and displaying of button b2
b2 = Button(app, text="Banana", command=lambda: which_button("Banana"))
b2.grid(padx=10, pady=10)

Step 6: Finally, create an infinite loop for displaying the app on the screen.

app.mainloop()

Example: 

In this example, if the text 'It is an apple' is printed on the screen, we get to know 'Apple' button is pressed, else when 'It is a banana' is printed on the screen, we get to know 'Banana' button is pressed.

# Import the library tkinter
from tkinter import *
# Create a GUI app
app = Tk()
# Create a function with one parameter to indicate which button was clicked
def which_button(button_text):
    # Printing the text when a button is clicked
    print(f"Button clicked: {button_text}")
# Creating and displaying of button b1
b1 = Button(app, text="Apple", command=lambda: which_button("Apple"))
b1.grid(padx=10, pady=10)
# Creating and displaying of button b2
b2 = Button(app, text="Banana", command=lambda: which_button("Banana"))
b2.grid(padx=10, pady=10)
# Make the infinite loop for displaying the app
app.mainloop()

Output:
