In order to structure the layout of the widgets in an application, we generally use the tkinter grid system. A grid system comprises rows and columns in which widgets are aligned. If we want to configure any widgets, then we can use the grid row and columns properties.Consider, if a widget is aligned such that there is extra space left, then we can add the weight property which enables the column to grow. A non-zero weight enables the column width to grow in the screen size if there is any extra space left. However, if the weight is zero, then ...

If we want to make the label text underlined, then we can use the underline property in the font attribute.Example#Import the required library from tkinter import* #Create an instance of tkinter frame win= Tk() #Define geometry of the window win.geometry("750x250") #Create a Label widget label= Label(win, text= "Hey, ...
