The imports we've seen so far are called absolute, that is, they define the whole path of the module that we want to import, or from which we want to import an object. There is another way of importing objects into Python, which is called a relative import. It's helpful in situations where we want to rearrange the structure of large packages without having to edit sub-packages, or when we want to make a module inside a package able to import itself. Relative imports are done by adding as many leading dots in front of the module as the number of folders we need to backtrack, in order to find what we're searching for. Simply put, it is something such as this:

from .mymodule import myfunc 

For a complete explanation of relative imports, refer to PEP 328 (https://www.python.org/dev/peps/pep-0328/). In later chapters, we'll create projects using different libraries and we'll use several different types of imports, including relative ones, so make sure you take a bit of time to read up about it in the official Python documentation.
