Example: radius = 5 area = 3.14 * radius * radius Comments: Add brief comments to explain complex sections or clarify intentions. Example: height = 5 width=5 # area calculation of rectangle area = height* width Whitespace Usage: Proper spacing enhances readability and clarity in code. Example: a=7 b=3 If a>b: print(“a is greater number”)
