Python Packages

Following is from David Beazley's talk.

• Explicit relative imports make refactoring of packages easier

  spam/
      __init__.py
      foo.py
      bar.py
  

  # bar.py
  
  from spam import foo
  

  👆 works, but, if we want to rename the spam package, we'd have to go in the code and refactor the import above.

  Relative imports make this easier.

  from . import foo
  

  Use leading . to move up the hierarchy.
