General handlers implementation.

Implement operation with collection of objects (handler-objects) same as a single object.

Quik start.

Program source:

   def _debug():
       import sys
       h1=sys.stdout
       h2=sys.stderr
       ho=Handler()
       ho.handler_add(h1,h2)
       ho.write('Test handlerE{\}n')

In this programm you add two handler-objects (stdout and stderr) in Handler ho. Then you call function from this handler-objects. Detail of function calling:

In first you get new Handler object with attributes write used as handler-object ho.write.
You do function call for each handler-object ('Test handler\n').
