Python Tkinter Entry Widget
The Entry widget in Tkinter is a powerful tool for accepting single-line text input from users. It plays a crucial role in building interactive Python applications, especially those requiring user data entry. For multi-line text input, Tkinter’s Text widget should be used instead.

w = Entry(parent, options)
Key Options in Tkinter Entry Widget
Here are some essential options for configuring the Entry widget:
| Option | Description |
|---|---|
bg | Sets the background color of the widget. |
bd | Defines the border width in pixels. |
cursor | Changes the mouse pointer type when hovering. |

highlightcolor | Specifies the highlight color when the widget gains focus. |
highlightthickness | Sets the thickness of the highlight border. |
insertbackground | Specifies the color of the insertion cursor’s background. |
insertborderwidth | Sets the width of the 3D border around the insertion cursor. |
insertontime | Defines how long the cursor remains visible in each blink cycle. |
justify | Aligns the text (left, right, or center). |
relief | Defines the widget’s border style (default is FLAT). |
selectbackground | Sets the background color for selected text. |
show | Masks the text for password input (e.g., *). |
textvariable | Links the Entry widget to a Tkinter StringVar object. |
width | Specifies the widget’s width. |
xscrollcommand | Links the Entry widget to a horizontal scrollbar. |
Example: Basic Tkinter Entry Widget
from tkinter import *
top = Tk()
top.geometry("400x250")
Label(top, text="Name").place(x=30, y=50)
Label(top, text="Email").place(x=30, y=90)
Label(top, text="Password").place(x=30, y=130)
Button(top, text="Submit", activebackground="pink", activeforeground="blue").place(x=30, y=170)
Entry(top).place(x=80, y=50)
Entry(top).place(x=80, y=90)
Entry(top).place(x=95, y=130)
top.mainloop()
Output: The interface will display Name, Email, and Password entry fields with a Submit button.
Tkinter Entry Widget Methods
Tkinter provides useful methods for handling data inside the Entry widget:
| Method | Description |
|---|---|
delete(first, last=None) | Deletes the specified range of characters. |
get() | Retrieves the text written in the widget. |
icursor(index) | Changes the insertion cursor position. |
insert(index, s) | Inserts text at the specified position. |
select_clear() | Clears the current selection. |
select_range(start, end) | Selects text between the given indices. |
xview(index) | Links the Entry widget to a horizontal scrollbar. |
Example: Simple Calculator Using Tkinter Entry Widget
import tkinter as tk
from functools import partial
def call_result(label_result, n1, n2):
try:
result = int(n1.get()) + int(n2.get())
label_result.config(text="Result = %d" % result)
except ValueError:
label_result.config(text="Invalid Input")
root = tk.Tk()
root.geometry('400x200')
root.title('Calculator')
number1 = tk.StringVar()
number2 = tk.StringVar()
tk.Label(root, text="A").grid(row=1, column=0)
tk.Label(root, text="B").grid(row=2, column=0)
labelResult = tk.Label(root)
labelResult.grid(row=7, column=2)
tk.Entry(root, textvariable=number1).grid(row=1, column=2)
tk.Entry(root, textvariable=number2).grid(row=2, column=2)
tk.Button(root, text="Calculate", command=partial(call_result, labelResult, number1, number2)).grid(row=3, column=0)
root.mainloop()
Output: This example creates a simple calculator that adds two numbers entered by the user.
