How to Get the Value of an Entry Widget in Tkinter?

Tkinter, a standard GUI (Graphical User Interface) toolkit for Python, offers various widgets to create interactive applications. Among these widgets, the Entry widget allows users to input text or numerical data. Often, developers need to retrieve the value entered by the user in an Entry widget for further processing or validation. In this article, we'll explore how to accomplish this task in Tkinter.

Get the Value of an Entry Widget in Tkinter

Below are some of the ways by which we can get the value of an entry widget in Tkinter:

Approach 1: Using a Button Click Event

In this approach, we'll create an Entry widget and a button. When the button is clicked, the value entered in the Entry widget will be retrieved and displayed.

import tkinter as tk

def get_entry_value():
    value = entry.get()
    print("Entry value:", value)

# Create the Tkinter window
window = tk.Tk()
window.title("Entry Widget Value Retrieval")

# Create an Entry widget
entry = tk.Entry(window)
entry.pack()

# Create a button to trigger value retrieval
button = tk.Button(window, text="Get Entry Value", command=get_entry_value)
button.pack()

# Start the Tkinter event loop
window.mainloop()

Output:

Approach 2: Using the bind Method with Return Key Press

In this approach, instead of using a button click event, we'll retrieve the value when the user presses the return key after entering text into the Entry widget.

import tkinter as tk

def get_entry_value(event):
    value = entry.get()
    print("Entry value:", value)

# Create the Tkinter window
window = tk.Tk()
window.title("Entry Widget Value Retrieval")

# Create an Entry widget
entry = tk.Entry(window)
entry.pack()

# Bind the return key press event to get_entry_value function
entry.bind("<Return>", get_entry_value)

# Start the Tkinter event loop
window.mainloop()

Output:

Conclusion

Retrieving the value of an Entry widget in Tkinter is a fundamental task when developing GUI applications. By following the steps outlined in this article, you can easily retrieve the user-entered data and integrate it into your Tkinter applications for further processing or validation. Experiment with different event triggers and actions to tailor the functionality to your specific application needs.
