AsyncSSH and timeout

[Standard User]

Good day,
I'm trying to run multiple SSH clients using AsyncSSH lib. This is an example 
from manual, which works fine: http://pastebin.com/zh4zymeQ

The problem is, it is not possible to directly set connect timeout in 
run_client() function. However, the manual says:
"asyncio calls can be wrapped in a call to asyncio.wait_for() or asyncio.wait() 
which takes a timeout and provides equivalent functionality."

So I tried to modify run_client() like this: http://pastebin.com/mH7pBuuf
But it spits out a syntax error. I also tried countless variations of it, but 
still no luck. Could someone more knowledgeable help me to set the damn timeout?

Newbie to python. Very newbie question

[ReviewBoard User]

Hi
I am a newbie to python and am trying to write a program that does a
sum of squares of numbers whose squares are odd.
For example, for x from 1 to 100, it generates 165 as an output (sum
of 1,9,25,49,81)

Here is the code I have
print reduce(lambda x, y: x+y, filter(lambda x: x%2, map(lambda x:
x*x, xrange
(10**6 = sum(x*x for x in xrange(1, 10**6, 2))

I am getting a syntax error.
Can you let me know what the error is?

I am new to Python and am also looking for good documentation on
python functions. http://www.python.org/doc/ does not provide examples
of usage of each function

  Hello,
 
  The answer is it depends, or 4 on your list of responses.
 
  You can write pure python on a Linux machine and it will run fine on
  Windows as long as you've taken care to program in a portable fashion.

 And not use modules not yet converted to microsoft, seems to happen from
 time
 to time.


  if you have C-extensions in
  your code you'll need to compile them over Windows.  If you want to
  program against the Windows API you'll need access to a Windows box.

 You can always cross compile, not only over OS but even CPU architecture,
 but
 of course testing will be more difficult, on x86 based Linux you can use
 wine
 or similar to test, but can give you some differences to run on a native or

Re: Python why questions

[Default User]

Not to prolong a good food fight, but IIRC, many years ago in QBasic,
one could choose

OPTION BASE 0

or

OPTION BASE 1

to make arrays start with element [0] or element [1], respectively.  Could
such a feature be added to Python without significantly bloating the
interpreter?

Then, if starting with [0] works for you, nothing really changes.  And if
starting with [1] works for you, then you are not made to feel like a
second-class citizen, and about as welcome as a dimwit at the Mensa
meeting.

Isn't Python supposed to be simple and accessible, and therefore fun?

Python why questions

[Default User]

From the emperor's new clothes department:

1)  Why do Python lists start with element [0], instead of element [1]?
Common sense would seem to suggest that lists should start with [1].

2)  In Python 3, why is print a function only, so that: print Hello, World
is not okay, but it must be print(Hello, World) instead?  (Yeah, I know:
picky, picky . . . )

3)  In Python 3, why does 2.0 / 3.0 display as 0., but 8 *
3.57 displays as 28.56 (rounded off to 2 decimal places)?  And yet, in
Python 2.6, 8 * 3.57 displays as 28.559?

And we wonder why kids don't want to learn to program.

processing of one file is an easy task but how do i process many files?
I tried reading that files in to a list and looping over the list

Hi,

  seems like the fileinput module works fine for me though i am having
quite an issue with the paths.

if i do:


something = fileinput.input(/some/absolute/path/to/list/file.txt)
#the text file contains absolute paths
for line in something:
data=scipy.io.array_import.read_array(line)
print data

it claims that the paths given in the textfiles don't exist no file or
directory though taking one entry from the textfile and inserting it
directly to the command does its job...

Any idea?

Thanks so far

Scraping information from webpages falls apart in two tasks:

1. Getting the HTML data
2. Extracting information from the HTML data

It looks like you want to use Internet Explorer for getting the HTML  
data; is there any reason you can't use a simpler approach like using  
urllib2.urlopen()?


Once you have the HTML data, you could feed it into BeautifulSoup or  
lxml.


Mixing up 1 and 2 into a single statement created some confusion for

So, if I understand you correctly, you want your program to do the

2. Look for a link identified by the text CNN Shop
3. Extract the URL for that link.

The result would be http://www.turnerstoreonline.com

Problem with urllib2.urlopen() opening a local file

[deja user]

I want to use urlopen() to open either a http://... file or a local
file File:C:/...  I don't have problems opening and reading the file
either way.  But when I run the script on a server (ArcGIS server),
the request won't complete if it was trying to open a local file.
Even though I call close() in either case, something seemed to be
preventing the script to complete if urlopen is trying to open a local
file.  I wonder if there is anything else I should do in the code to
kill the file descriptor, or if it is a known issue that something is
leaking

When running the script standalone, this is not an issue.

Re: Serial connections and threads in a GUI

[user]

Aaron Hoover wrote:
 I have a wx-based GUI application that I'd like to have read streaming
 data from a serial port and plot that data using matplotlib and a figure
 canvas. It's a robotic application where the workflow goes something
 like this:
 
 1) Connect to robot
 2) Configure robot settings
 3) Command robot to do something for time, t
 - While robot does something, read sensor data and plot
 4) End of t seconds, resume at (2)
 
 I have the application reading from the serial port in a separate
 thread, but my problem is this - I'd like the user to be able to write
 to the serial port by interacting with the GUI between runs. However,
 the infinite loop running inside the thread responsible for receiving
 data has exclusive access to the serial connection object.
 
 Because of how the application works, I know that I won't need to write
 to the serial port when I'm in the middle of receiving data, so that
 simplifies things somewhat. But, how can I allow the thread access to
 the connection for reading, but then have it give up control over the
 connection when it's done so the main GUI thread can access the
 connection again for writing?
 
 Currently, I have the thread's run() method exit when it's done
 receiving data. But, that means that I can only receive data again using
 the same thread by calling run(), blocking the main GUI thread from
 updating the plot until it completes.
 
 This is my first go at using threads in Python, so I'm sure there's a
 straightforward way to do this that I'm just missing. At any rate,
 thanks in advance for your patience and assistance.
 
 
 Thanks,
 Aaron
Use a few queue objects (see the queue module). Your serial port thread
can have an rx and a tx queue. Your gui program just checks the rx queue
whenever it wants and puts data into the tx queue whenever it wants, and
the queue objects do all the worrying about synchronizing and thread
safety and such. Works like magic!

Re:  from coin_toss import coin_toss


My understanding is that this line makes the coin_toss() function in the 
coin_toss.py file available to the toss_winner() function.  Is that what your 
explanation on this point meant (i.e. ... and sets the 
local variable coin_toss to the value of coin_toss in the module coin_toss)?


That is the effect of the statement, however there are cases when the from 
coin_toss import coin_toss may result in a different value in the module. This 
is because:
from coin_toss import coin_tosseffectively does:import coin_tosscoin_toss = 
coin_toss.coin_toss

While this normally works as intended, it can have some unexpected effects. 
Take, for example:

-ALPHA.PY-from gamma import testimport betaimport gamma
test = 2gamma.test = 3print gamma.testprint test
print beta.testprint beta.gamma.test
-BETA.PYfrom gamma import testimport gamma

GAMMA.PY---
test = 1



With this setup, you'll get the output: import Test.alpha321
3


If, however, you change gamma to read:test = ['1']


and the lines in alpha:

test = 2gamma.test = 3
to read:
test.append('2')gamma.test.append('3')
you'll get:
 import Test.alpha['1', '2', '3']['1', '2', '3']['1', '2', '3']['1', '2', 
 '3']



As this shows, the from MODULE import VALUE method rebinds the varible from 
another module in the local scope, and thus does:import MODULE
VALUE = MODULE.VALUEdel MODULE

This means that for some types, the value in MODULE and the value in the local 
scope may not be the same and other times they may be the same.


For your purposes, you'll notice no real difference. However this is something 
to keep in mind.

 

Re:  ... within a function, a different namespace exists , and ... you

P..S.  I didn't see your reply to my post in the comp.lang.python Google

Lets look at what is happening on a few of the lines here:

First:from coin_toss import coin_toss


imports the module coin_toss and sets the local variable coin_toss to the value 
of coin_toss in the module coin_toss.





Second:
coin_toss = coin_toss()

calls the function bound to the name coin_toss and assigns the result to 
coin_toss. Now this appears to be what you want (and run outside a function it 
would work as you intend, the first time). However, within a function, a 
different namespace exists, and Python sees that you are assigning to 
coin_toss, and thus uses the local version of that variable everywhere else 
within the function. As such, Python is attempting to call the 
local variable coin_toss, which has not yet been assigned too.







While not really the correct solution, you may want to look into the 
global keyword for more information about your problem.

 When Python sees this assignment to coin_toss as it compiles the
 toss_winner() function, it marks coin_toss as a local variable and
 will not consult global scope when looking it up at runtime

 To fix the problem, rename the variable so its name differs from that
 of the coin_toss() function.

OP
As an additional note: in Python, everything is an object - including modules, 
classes, and, yes, functions -, so there's no distinct namespace for functions 
or classes. If you try to execute the coin_toss = coin_toss() statement at 
the top level (or declare name 'coin_toss' global prior using it in the 
toss_winner function), you wouldn't get an UnboundLocalError, but after the 
very first execution of the statement you would probably get a TypeError on 
subsquent attempts to call coin_toss:

 def coin_toss():
      print coin_toss called
      return 42

I installed PyGUI-2.0.1 on Windows (32 bit, non Administrator access).
I got the following error in 2.0.1 when attempting the BlobEdit example:

python debugger tips?

[just . another . random . user]

Hi All,

I'm switching to python from perl, and like the language a ton, but I
find pdb and pydb to be vastly inferior debuggers to the perl version.

In particular, I've grown very used to stepping into arbitrary
functions interactively.  For instance, in perl you can do this:

casqa1:~ perl -de 42

Loading DB routines from perl5db.pl version 1.28
Editor support available.

Enter h or `h h' for help, or `man perldebug' for more help.

main::(-e:1):   42
  DB1 sub foo {return 42}



  DB2 s foo()
main::((eval 7)[/usr/local/lib/perl5/5.8.6/perl5db.pl:628]:3):
3:  foo();


  DB3 s
main::foo((eval 6)[/usr/local/lib/perl5/5.8.6/perl5db.pl:628]:2):
2:  sub foo {return 42};
  DB3



Which is quite awesome; I don't have to restart the program if I want
to step through a given function call with a different set of values.

Does anyone have advice on any macros or something that i could use to
do this?

Additionally, what do people recommend as good advanced python
debugger guides?  Explaining breakpoints and all is useful, but I
really want to know how to make sophisticated macros and interact with
the debugger from the interactive prompt.

Thanks!

I don't think you can ever catch grep.  Searching is its only purpose in 
life and its very good at it.  You may be able to come closer, this 
thread relates.


http://groups.google.com/group/comp.lang.python/browse_thread/thread/2f564523f476840a/d9476da5d7a9e466

This relates to the speed of re.  If you don't need regex don't use re. 
 If you do need re an alternate re library might be useful but you 
aren't going to catch grep.

 While creating a log parser for fairly large logs, we have run into an

Its very hard to beat grep depending on the nature of the regex you are 
searching using. The regex engines in python/perl/php/ruby have traded 
the speed of grep/awk for the ability to do more complex searches.

This might not be your problem but if it is you can always popen grep.

 Cox uses a pathological regex (regex = a? * 29 + a * 29, in

Nobody but you can anawer this question. You'll have to try.
Does PHP have more features?
PHP has a rich library which probably outperforms any Python alternative
in terms of features. But this doesn't necessarily mean that you will
develop faster in PHP. The problem with Python is that you have to make
a choice among many solutions (roughly ordered by inreasing complexity):
- plain cgi
- Quixote
- modpython
- CherryPy
- Spice
- Webware
- Twisted
- ZOPE
...
Have a look at http://www.python.org/topics/web/
How about the speed  of execution?
There is no simple answer. Both languages use C functions which are
executed at CPU speed. But with interpreted code Python seems to be
approximately 3-4 times faster than PHP (http://dada.perl.it/shootout/).
What are the pros and cons?
