Import the math package. Now you can access the constant pi with math.pi. Calculate the circumference of the circle and store it in C. Calculate the area of the circle and store it in A. As our application program grows larger in size with a lot of modules, we place similar modules in one package and different modules in different packages. This makes a project program easy to manage and conceptually clear. Similar, as a directory can contain sub-directories and files, a Python package can have sub-packages and modules.
