Introduction

Transferring files with bluetooth or via USB is practical, but I have been often wondering how practical it would be to transfer using FTP. FTP is supported pretty much everywhere. I recently played with PyS60 - A Python implementation for S60. It's compatible with 3rd and 5th edition devices and thus with the N97. To my surprise it worked like a charm. It should work equally well for all S60 3rd and 5th edition devices.

After a quick search where I didn't find a singleton implementation for new-style classes in Python. For classic classes there's the excellent Borg pattern. So here's singleton for new-style classes:

class Singleton(object):

      __instance = None

      @classmethod
      def getInstance(cl):
          """
          Get the global engine instance or create one if none exists yet.
          """
          if cl.__instance is None:
              cl.__instance = cl()

          return cl.__instance
