You mean you want to read the contents of a file uploaded to the Zope ODB, 
so it's in Zope itself? Or do you mean to read a file from the filesystem 
on the server Zope runs on?

The first can be done through the self object, either by referencing it 
directly (self.objectName) or, if the id of the object contains illegal 
Python characters (like the dot in Book1.txt), you could use getattr(self, 
'objectName'). self.__getitem__('objectName') also works.

File objects can be read by accessing their .data attribute. So, you can 
access the data on the Book1.txt File object with:

   data = getattr(self, 'Book1.txt').data

or

   data = self.__getitem__('Book1.txt').data

If you want to access files on your local filesystem, you should indeed 
pass in a full path:

     file = open(fullPathToFile, 'r')
     data = file.read()
     file.close
