I just read several tutorials on iteratee, i find that iteratee is

> yield EOF

> def print_chunks(print_empty, generator):
> for chunk in generator:
> if chunk==EOF:
> print 'EOF'
> return
> if len(chunk)==0 and not print_empty:
> continue
> print chunk
>
> print_chunks(True, enum_file(2, "data"))
