Question about installing python and modules on Red Hat Linux 6
I am developing a python application as a contractor. I would like to know if someone can provide me with some insight into the problems that then infrastructure team has been having. The scope of the project was to install python 2.7.8 and 4 modules/site packages on a fresh linux build. The first team failed after almost 3 weeks of work. Then they put their star Linux administrator on the task and it took almost a week of considerable effort. I was able to perform the same task on my windows desktop in less than a morning. I cannot get a straight answer as to what the problems are. They just seemed to be building and rebuilding all of the components from scratch. Can anyone provide me with insight as to the scope what the problem could have been? Thanks -- https://mail.python.org/mailman/listinfo/python-list
Python Paramiko between Linux and Windows Server -- no output obtained from Windows for "dir" or "cd" commands
Hello There:
I am using Python 2.7.6 and Paramiko module (on a Linux server) to connect to a
Windows server and send some commands and get output. I have a connect function
which takes IP, username and password of the remote Windows server and I get an
sshobj when that happens. How do I use it to send remote calls is my question?
If it were a local system, I would just say "os.system" but not sure about the
remote calls. Can someone help?
My code looks like below: sys.path.append("/home/me/code")
import libs.ssh_connect as ssh
ssh_obj = ssh.new_conn(IP, username, password)
stdin, stdout, stderr = ssh_obj.exec_command("dir") #since the remotesystem
I am SSHing into is Windows.
my "new_conn" looks like this:
import paramiko
def new_conn(IP, username, password):
ssh_obj = paramiko.SSHClient()
ssh_conn.set_missing_host_key_policy(paramiko.AutoAddPolicy())
ssh_conn.connect(IP, username, password), timeout=30)
return ssh_obj
if I replaced "dir" with "ipconfig" it works fine. I wonder how I can make
"dir" work - or for that matter.. with "cd /path/to/dir"?
I know for paramiko's ssh connection to work, i need cygwin installed on a
Windows. Objective is to run commands remotely from a Linux to a Windows server
and then process the output again on Linux server or on Windows itself.
I am confused because, "ipconfig" sent from Linux to Windows using
"ssh_obj.exec_command("ipconfig")" works but not "ssh_obj.exec_command("dir")"
- tried giving the path like "cd C:\Users\Administrator" for cmd or "cd C:"
followed by "cd Users/Administrator" like in Cygwin. Neither of them work.

Thanks Peter but I got no output from your suggestion either.!

Issuing commands using "exec_command()" of paramiko AND also sending commands together
Using paramiko's exec_command(), i would like to send a command, process its output and do it for several other commands. I notice that its not quick enough or something like that. How would I handle that scenario AND also providing multiple commands together (there is 1 post on stackoverflow for issuing multiple commands but I am not sure if someone has tried it. It didnt work for me! Thanks! -- https://mail.python.org/mailman/listinfo/python-list
strptime dilemma with Python 2.5
Hello, I have a date string looking like the following: "Sun May 30 07:25:17 2010" With Python 2.6, the %f is supported (it parses the microseconds), so that this statement works: dt = datetime.strptime(s, "%a %b %d %H:%M:%f %Y") However, with Python 2.5, (which is supported on the live Webfaction server I'm using), %f is not supported. Is there a straightforward way to simply ignore the :17 microseconds in the original string? Maybe force it to "00" ? - but without having to actually change the original string by removing the ":17" ? If I simply leave out the ":%f" in the strptime call, I get back a " ValueError: time data did not match format: data=Sun May 30 19:33:54 2010 fmt=%a %b %d %H:%M %Y Hoping for a simple solution that someone is familiar with Thanks Steve -- http://mail.python.org/mailman/listinfo/python-list

Assigning to __class__ : bad form?
I've been wondering for a while about whether assigning to __class__ is bad form or not. Specifically, I mean doing so when some other method of implementing the functionality you're after is available (i.e. using an adapter, or something like the strategy pattern). To give an example and a non-example of what I'm talking about, consider the following recipes from the online Python Cookbook: Ring Buffer: http://aspn.activestate.com/ASPN/Cookbook/Python/Recipe/68429 In this case, I think the assignment to __class__ just obfuscates things, and the example would be better coded as a single class. On the other hand, Fast copy of an object having a slow __init__ : http:// aspn.activestate.com/ASPN/Cookbook/Python/Recipe/66507 This seems like a reasonable use case for assigning to __class__ (except that it's already implemented in the 'new' module, but, read the Martelli- bot's comments near the end of the recipe). I consider this a reasonable use case for assigning to __class__, because, short of the 'new' module, I don't see any other way to accomplish it. So, what is the opinion of the broader Python community? Is code that assigns to __class__ just clever trickiness to be avoided, or is it sometimes a good thing? -- code.py: A blog about life, the universe, and Python http://pythonista.wordpress.com ** Posted from http://www.teranews.com ** -- http://mail.python.org/mailman/listinfo/python-list
Change in interactive interpreter?
I remember the interactive interpreter used to define the name _ to return the value of the last expression that was evaluated. However, I tried it just today and got a NameError. Is this a change in the interpreter or is there a configuration option I need to set to enable it?

Re: How to kill a thread?
It's always been my understanding that you can't forcibly kill a thread in Python (at least not in a portable way).

Python equivalent of call/cc?
Yesterday, I was hacking around a bit, trying to figure out how to
implement the semantics of call/cc in Python. Specifically, I wanted to
translate this Scheme code to equivalent Python:
(define theContinuation #f)
(define (test)
(let ((i 0))
(call/cc (lambda (k) (set! theContinuation k)))
(set! i (+ i 1))
i))
(test)
(theContinuation)
(theContinuation)
Incidentally, those last three lines evaluate to 1, 2, and 3,
respectively.
The best Python translation I could come up with was something like this
(targeted at Python 2.5):
import inspect
theContinuation = None
def call_cc (f):
f (inspect.currentframe().f_back)
def invoke (c):
exec c.f_code in c.f_globals, c.f_locals
def test():
i = 0
call_cc (lambda k: globals().update({'theContinuation' : k }))
i = i + 1
print i
test()
invoke (theContinuation)
invoke (theContinuation)
Now, this code is wrong on a number of levels [I am indeed aware of
exactly how ugly that lambda is...], but, in particular, my
continuations / stack frames don't seem to be resuming at the right
point. I'd expect invoke (theContinuation) to restart on the line
immediately following call_cc, but it does not. Not surprisingly, the
output is also wrong. (I get 1, 1, and 1 rather than 1, 2, and 3.)
Can anyone help me by, perhaps pointing out some silly error I made?
Failing that, can someone show me a working implementation of call/cc
(preferably based on some form of stack inspection)?
Thanks!

Building python-svn from source
First of all, I apologize if this would be more appropriate for python- dev, but I don't normally subscribe to that list, and felt it would also be of general use, so I'm having problems building the latest Python 2.6 and 3.0 from subversion, and I'm not sure how to resolve the problem. In each case, configure executes without problem, but, when I execute 'make', I get this error (the same one for both 2.6 and 3.0): ./Parser/asdl_c.py -h ./Include ./Parser/Python.asdl Must specify exactly one output file make: *** [Include/Python-ast.h] Error 1 Am I doing something wrong? If not, how do I work around this error?

Martin, Thank you so much! In fact, I did have a python executable on my PATH in ~/bin that was screwing things up. After I moved it (thus leaving the system default python as the only python executable on my PATH), the build process went smoothly (except for not being able to find a few libraries for some C extensions, but I think I can fix that). I now have working python2.6 and python3.0 executables to play with, thanks to you. :-) -- code.py: A blog about life, the universe, and Python http://pythonista.wordpress.com ** Posted from http://www.teranews.com ** -- http://mail.python.org/mailman/listinfo/python-list
