I've been scanning Python in a Nutshell, but this seems to be either
undoable or so subtle that I don't know how to do it.
I want to subclass a base class that is returned from a Standard Library
function (particularly, subclass file which is returned from open). I
would add some extra functionality and keep the base functions, too.
But I am stuck.
E.g.
class myfile(file):
def myreadline():
#code here to return something read from file
Then do something like (I know this isn't right, I'm just trying to
convey the idea of what I would like)
mf=myfile()
mf=open("Afile","r")
s=mf.myreadline() # Use my added function
mf.close() # Use the original file function
Possible in some way? Thanks in advance for any clues.
