Question

I’m trying to upload lots of files using python’s ftplib.
What kind of exception should I catch to be sure the problem is a connection error (so I can re-connect)?

---

Edit:
I tried all_errors in this scenario:

• Connected to FTP server by ftplib and paused application (via debugger) before file upload
• Closed connection via server
• Resumed Application

With this code:

        try:        
            self.f.cwd(dest)
            return self.f.storbinary(('STOR '+n).encode('utf-8'), open(f,'rb'))
        except ftplib.all_errors as e:
            print e

exception caught but all_errors was empty:

e   EOFError:   
    args    tuple: ()   
    message str:

You can look it up in the documentation: http://docs.python.org/2/library/ftplib.html#ftplib.error_reply
