How to Retrieve the Value of an Entry Widget in Python Tkinter?

Estimated read time 2 min read

To retrieve the value of an Entry widget in Python Tkinter, you can use the get() method. Here’s an example:

import tkinter as tk

def get_entry_value():
    value = entry.get()
    print(f"The value is: {value}")

# Create a Tkinter window
window = tk.Tk()

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

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

# Start the Tkinter event loop
window.mainloop()

In the above code:

  1. First, you import the tkinter module as tk for convenience.
  2. Define a function called get_entry_value() that retrieves the value of the Entry widget using the get() method. In the example, it simply prints the value to the console.
  3. Create a Tkinter window using the Tk() constructor.
  4. Create an Entry widget using the Entry() constructor and pack it to add it to the window.
  5. Create a button using the Button() constructor. Set the text parameter to the desired label for the button and the command parameter to the function get_entry_value to bind the button click event to the function.
  6. Pack the button to add it to the window.
  7. Finally, start the Tkinter event loop using the mainloop() method of the window. This allows the window to be displayed and handles user interactions.

When you run the code and enter a value into the Entry widget, clicking the “Get Value” button will invoke the get_entry_value() function and print the retrieved value to the console.

You can modify the get_entry_value() function to perform any desired processing or use the retrieved value in your application logic.
