[Tutor] importing modules and packages

[neubyr]

Is it possible to tell whether import statement is importing a module
or package?  I am going through some example code with some import
statements - like 'import os, sys, time', 'import packed'. I know os,
sys and time are (built-in) modules and 'packed' is a package here .
But can I determine whether it's a package or module using any
command/method or by following some naming convention?

- thanks,
