Differences between pack() and configure() in Tkinter Widgets

We use various geometry managers to place widgets on a Tkinter window. A geometry manager tells the application how to organize and arrange widgets within the window. Using a geometry manager, you can configure the size and coordinates of widgets within the application window.

In Tkinter, the pack() method is one of three geometry managers. The others are grid() and place(). The pack() geometry manager is typically used to provide a way to fill and arrange widgets.

To explicitly configure the properties and attributes of a widget after it has been defined, use the configure() method. The configure() method is also used to configure widget properties, including sizing and arrangement attributes.

Example

In the following example, we create a Label widget and a Button widget. The pack() and configure() methods can be used to efficiently configure the properties and attributes of both widgets.

#Import required libraries
from tkinter import *

# Create a Tkinter frame or window instance
win = Tk()

# Set the window size
win.geometry("700x350")

# Define a function
def close_win():
   win.destroy()

# Create a label
my_label = Label(win, text="Hello everyone!", font=('Arial 14 bold'))
my_label.pack(pady= 30)

# Create a button
button = Button(win, text="Close")
button.pack()

# Configure label properties
my_label.configure(bg="black", fg="white")
button.configure(font= ('Monospace 14 bold'), command=close_win)

win.mainloop()

Output

Running the above code will display a window with Button and Label widgets. You can configure the properties of these widgets by manipulating the values in the configure() method.
