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
