[Tutor] how useful is __del__()

[Carsten Bohnens]

hey,
I wrote a small class that does some ftp work for me:
#myftpclass.py
class myftp:
   def __init__(self, ...):
      ...
   def connect_and_login(self):
      ...
   def do_foo(self):
      ...
   def do_bar(self):
      ...
   #here comes the interesting part for me
   def goodbye(self):
      self.currenthost.quit()
      print 'Disconnected.'
my actual scripts then look like that:
#movesomedata.py
from myftpclass import myftp
ftp = myftp(--host, username, etc...--)
ftp.connect_and_login()
ftp.do_foo()
ftp.do_bar()
ftp.do_foo()
ftp.goodbye()
I am wondering if there is a way to get the disconnect without calling 
the funcion goodbye or doing ftp.currenthost.quit() by youself and if 
that could be done by defining a __del__() funcion in myftpclass. like, 
the end of the script is reached, or an exception is raised somewhere, 
disconnect.
or should I do something like this instead:

#movesomedata2.py
from myftpclass import myftp
try:
   ftp = myftp([host, username, etc...])
   ftp.connect_and_login()
   ftp.do_foo()
   ftp.do_bar()
   ftp.do_foo()
finally:
   ftp.goodbye()
thanks for all answers
