Subject: [Python Wpg] paramiko tunneling?
Message-ID: <20090207220214.85rudwqi8048cc4c@webware.cc.umanitoba.ca>
Hi,
I am a newbie to SSH (paramiko) usage. I want to use paramiko to
tunnel a TCP/IP
connection over ssh, from a local machine to the same remote machine
I connect to via paramiko-ssh.
Forwarding?is trivial when using command-line ssh
(ssh -L <loca;port>:localhost:<remoteport> <remotehost>)
but I can't figure out how to do it using paramiko (forwarded-tcpip?) and
keep getting not very illuminating errormessages. More "normal" things like
remote commands work without a hitch. Any help would be appreciated.

We're only a week away with no topic. Thoughts?
I may be able to give a short presentation on writing Python 2.6 code
such that it works in Python 3.0, which would just be my rehash of
what's been published on this topic based on my Python tutorial
preparations.
Stuart.

I'll present on 2.6 to 3.0 suggestions, and if there's interest,
possibly also on ways to understand classes better by trying to create
them manually.
We'll also have time for this suggestion:
How about a discussion about this article by Guido about class
syntax and implementation in Python:
http://python-history.blogspot.com/2009/02/adding-support-for-user-defined-classes.html

A review of classes would be great. I seem stuck in the past when it
comes to programming. :-)

I'll read it before coming to the meeting tomorrow.

Subject: [Python Wpg] Swapping object attribute values
Message-ID: <1235654158.9135.13.camel@localhost>
I like the way you can swap the values of variables in Python by saying
something like:
a, b = b, a
but suppose I want a function that will swap arbitrary attributes on an
object. Could I code that using the tuple unpacking assignment style? I
ended up doing this:
def transpose(self, from_attr, to_attr):
"""Transpose the co-ordinates from one axis to another"""
to_val = getattr(self,to_attr)
setattr(self, to_attr, getattr(self, from_attr))
setattr(self, from_attr, to_val)
Is there a more compact, readable way to do this?
Regards,
Syd

Not knowing the context of your call to transpose, I wonder if instead
of writing
anObject.transpose('field1', 'field2')
why you wouldn't just write this:
anObject.field1, anObject.field2 = anObject.field2, anObject.field1

Probably makes more sense to do it that way. Simple is better than
complex *and* Flat is better than nested.
Thanks!
