Dynamic loading of python modules

Question

In python how do you dynamically add modules to a package while your program is running.

I want to be able to add modules to the package directory from an outside pr

Answer 1

To detect changes to a directory, on Linux, you can use pyinotify (here is a nice working example); on a Mac, fsevents (via the PyObjC package that comes with your Mac); on Windows, Directory Change Notifications via win32api (or the Python standard library ctypes module). AFAIK, nobody's wrapped up these various approaches into one portable package. (Of course, worst case, you can fall back to "lower tech" approaches such as periodic polling, as Tim Golden's article, perhaps with a touch of "alerts from an external process" via a signal, etc).

Once you do have the notification and the name of the new or modified module, the code you show in the question should work.
