To display the values in an entry widget in tkinter, you can set the value of the entry widget using the insert method. You can pass the string value that you want to display in the entry widget as an argument to the insert method. For example, if you have an entry widget named entry_widget and you want to display the value "Hello, World!" in it, you can do so by calling entry_widget.insert(0, "Hello, World!"). This will display the specified value in the entry widget at index 0.

How to clear the values in entry in tkinter?
To clear the values in an entry widget in tkinter, you can use the delete method to remove the existing text from the entry.
Here's an example code snippet that demonstrates how to clear the value in an entry widget:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 |
import tkinter as tk def clear_entry(): entry.delete(0, tk.END) root = tk.Tk() entry = tk.Entry(root) entry.pack() button = tk.Button(root, text="Clear", command=clear_entry) button.pack() root.mainloop() |
In this code, a function clear_entry is defined which uses the delete method to remove the text in the entry widget. The delete method takes two arguments, the start index (0 in this case) and the end index (tk.END which indicates the end of the text in the entry widget).
When the "Clear" button is clicked, the clear_entry function is called which clears the value in the entry widget.
