I used string.find but it does not work properly for the words.
Let suppose I want to find a number 324 in the  text

'45  324 45324'

there is only one occurrence  of 324 word but string.find()   finds 2
occurrences  ( in 45324 too)

 '45  324 45324'.split().count('324')
1

Marco,
Thank you for your help.
It works perfectly but I forgot to say that I also need to find the
possition of each word's occurrence.Is it possible that

 li = '45  324 45324'.split()
 li.index('324')
1
 

play with count and index and take a look at the  help of both

ciao
marco

Re: Initializing an attribute that needs the object

Hi. I want to have different handlers to do perform logic. The problem 
is the Handler requires an instance of the factory since it will use its 
own methods in conjunction with methods of the factory.

Once I have got a Factory instance I can give it a new handler (see 
below). It would be more flexible if I could provide a handle in 
constructor - but how to do this when it requires the object itself. 
Would I use a super for this sort of thing? Many thanks

when __init__ is called the object already exists.

class Factory:

   def __init__(self):
   self.some_handler = Handler(self)

f = Factory()
f.some_handler = AnotherHandler(f)

try this, should works:

class Factory:

def __init__(self):
self._some_handler = AnotherHandler(self)

maybe a class hierarchy is good for you

ciao
m.
