Interpreting your question as a general question of stylistics, my
experience is that a 3 line script often becomes a 10 line or a 50
line script at which point the direct printing will have to be
modified to create an internal data structure.
So on the whole I find it expedient to start with that assumption and
write it as:
def linesums(file):
return [sum(int(i) for i in l.split(';')) for l in open(file, 'r')]
Why change the OP's namings ? 'data' and 'line' were more suitable than 'i' and
'l'. Of course we're nitpicking, no one will get hurt.

Yes, l is an undesirable name because it can look like 1

The problem for me is that I don't actually know anything about writing a function that opens a network socket, and connects to that plugin und asks it for the information you require. That plugin should have some documentation which should tell you something about how to connect to it and how to request information. When you know that you can turn to the python documentation and find out how to do this in python. That's all really beyond me, all I can do is what I did so far, which is make it ask for your temperature value, and then test it to see if its an integer Then (I added this for testing) It asks for any temperature value. And if it exceeds the given limit, it rings an alarm. Until it freezes and becomes unresponsive :D If you have specific problems with code you have written, try to build up a minimal working example that shows the problem plus any error messages/exceptions/stack traces you get back. We might be able to help you with your code. I don't know how to make it 'query' or grab values constantly, if you don't mind my potentially incorrect terminology.

I don't know about the GPIB bus (which thisUSBTMClibrary seems to be trying to emulate), but most serial devices expect to provide one answer per read-write handshake. That is, you send one read command and get one answer back. That answer may contain several bytes, but I'd be surprised it it contained 10,000. The typical cycle is something like send-an-initialize, read-status, send-mode-set-up, read-status, send trigger command, read-answer… lather and repeat. (Or some logical equivalent of all that). On the assumption that theUSBTMCAPI handles most of that, I'd try usbkeith.read(n) where n is the number of decimal digits you expect to get back plus sign. 1 wasn't a good guess indeed - 2) I took a quick look at the Keithley and National Instruments web sites (where the documentation is at best, VERY poorly indexed and hard to search for). USBTMC*appears* to be a software layer designed to allow newer Tektronix and Keithley instruments to be driven using older software that drove GPIB equipment. To make matters worse, if I'm reading it right (I didn't study in detail) it appears to ALSO be providing a GPIB-like API to Windows versions of National Instruments LabView. 3) If I understand what you are trying to do, you want to go straight from python to the Keithley USB port, without detouring (USB-to-GPIB and GPIB back to USB). Yes indeed, that's exactly what I want 4) I did find (but did not try to read in detail) the following link: http://www.ni.com/white-paper/4478/en which documents direct USB control of instruments. The python serial library provides quite transparent control of reading and writing to the USB interface. Maybe following this link will get you going. Thanks for the link, but as you can see there they want to push NI- VISA forward as the solution, which under Linux means more complexity and surely isn't as simple to install as they claim, so if possible I'd avoid ni-visa. I'll experiment further Monday with read() and keep you informed regards, Jean I changed the program as below an experimentally found out I have to use an number of characters between 11 and 4095 I doesn't seem to make any difference which value I choose in that interval, however the results are as follows: 0.0077219 0.0295029; this is rubbish 0.0249596 0.261837; this should have been the first data pair 0.0499763 0.516741; this should have been the 2nd data pair 0.0750685 0.767388; this should have been the 3rd data pair 4th data pair is missing As you can see this approach suffers from the same buffer problem as the approach with readline did. One now good argue as a workaround: get rid of the first data pair and add an extra measure command for the missing data pair, however this still does not explain why this problem is there in Python and not in Octave and I also fear I'll get more trouble when sending combined commands e.g. such as that to create a staircase current So my question is, how to modify the Python-code such that the first data pair is indeed the first data pair thanks, jean Here follows the new code: #!/usr/bin/python

accessing an OLE Automation (IDispatch) server from python which requires the use of out params
I have an existing Windows application which provides an OLE Automation (IDispatch) interface. I'm not able to change that interface. I'd like to call it from a scripting language. I figure this would provide a nice quick way to invoke on the app. I initially tried this with Windows Powershell but ran into the following problem. I was able to create the object and invoke simple methods on it. However the interface for this app has methods which take out params. i.e. you pass in a reference to a variable and the server fills in the value. I couldn't get that to work. I finally gave up and decided it was just a limitation of Powershell, not being able to work with those out params. My next thought was to do it in python. I've been reading up on python and I've found a decent amount of into out there on doing OLE and I'm optimistic. But, I thought that I'd ask the question before digging too much farther into it... When calling an OLE Automation (IDispatch) server from python can I make use of out params defined by the interface? To get more specific, here's an example from the server's IDL for one of its methods. [id(15), helpstring(method GetSettingValue)] VARIANT_BOOL GetSettingValue(BSTR settingName, BSTR* settingValue); As you can see, you have to pass in an out param for settingValue. The server fills this in for you. And this is what I couldn't get to work in Powershell. Anyone know whether or not OLE from python will allow passing in out params?

date-time comparison, aware vs naive
I want to compare a user entered date-and-time against the date-and-time of a pdf file. I posted on this (how to get a file's date-time) before, was advised to do it like: import datetime, os, stat mtime = os.lstat(filename)[stat.ST_MTIME] // the files modification time dt = datetime.datetime.fromtimestamp(mtime) I am having problems with the comparison, that line is failing. I think I may have figured out the issue -- I think it is a matter of the file's time being 'aware' and the user-input date-time being 'naive'. The user-input date-time has a parameter type of date (calender and time tool supplied to enter), but is it 'aware'? The comparison is not working so I think that it is not aware. I can successfully compare two pdf file times against one another. So, is there a way to cast that user-input value (prints as 2/10/2012 3:19:57 PM) as an 'aware' date-time? How?

strptime - dates formatted differently on different computers
Follow-on question to this earlier topic - https://groups.google.com/d/topic/comp.lang.python/wnUlPBBNah8/discussion Was curious to know if there was a way to handle different user computers with different operating system set date formats. 2/10/2006 vs 2-10-2006, for example. Not an issue for my current task, but was just curious how this could be handled?

Don't think that it's possible with webbrowser, you should try with Selenium.
For example with sst (Simple Selenium Test), it open url in current
tab or create a new one if no one exists:
from sst.actions import *
go_to('http://www.ubuntu.com/')

Re: open URL in the current tab
Thanks. I've found something interesting since then:
https://addons.mozilla.org/en-US/firefox/addon/mozrepl/
https://github.com/bard/mozrepl/wiki
It allows you to connect to your Firefox via telnet. Then changing the URL:
content.location.href = new_url
However, for this you need to install this add-on.

Firstly, I'm going to assume here that this is a homework question; you haven't said so, but it seems rather more likely than the alternative (that you're actually going to use such an incredibly low-grade cipher and an interactive prompt like this). Please be honest about this; it's okay to ask for help, but we're not here to do your homework for you. (We do NOT want to help you to get a certificate you don't merit, then get a job using that certificate, and then write code that we'll be staring at in our next jobs. There are already more than enough incompetent programmers in the world; I'd rather that you either learn the material for real, or if you can't, fail the course honestly. Sorry if that sounds harsh, but I'm sure you'd rather that I didn't have a certificate entitling me to drive a truck on roads near you/your kids, because I do not know how to drive one safely.) Secondly, putting NEED HELP in your subject line doesn't, in fact, help. :) It just makes you sound demanding. So! On to the actual problem. What you need to do is find the letter that corresponds to the one you have. Decryption is the same as encryption but with the alpha and key switched, so I recommend creating a function that accepts those two as arguments - something like this: clear = ABCDEFGHIJKLMNOPQRSTUVWXYZ key = XPMGTDHLYONZBWEARKJUFSCIQV def crypt(msg,from,to): # and put your code in here # To encrypt: encrypted = crypt(original, clear, key) # To decrypt: message = crypt(encrypted, key, clear) The details of the encryption you can put together from John's and/or vbr's responses, but make sure you understand the code yourself. For example: What will each of them do with any non-alphabetic characters? Suppose your original message is HELLO, WORLD! - what will happen to the comma, space, and exclamation mark? Be sure you know *why* this is how it is, too. If you run into trouble, post your non-working code and exactly how it's not working, and we'll try to help you understand why it's not working. :) In the meantime, here's a document that you may want to familiarize yourself with: http://www.catb.org/esr/faqs/smart-questions.html It's a great explanation of the how and, more importantly, the why of asking questions of volunteer geeks.

definition. No indication of your OS, Python version, calling code,

Additionally I find the new code much easier to read.

By example:

import thesaurus
thes = thesaurus.Thesaurus
# I like to create a master global object called 'g'.
# No more 'global' statements for me.
g = thes()
g.prog = thes()
g['prog']['VERSION'] = '1.0' # I can do this like a normal nested dictionary
g.prog.VERSION = '1.0' # But isn't this so much cleaner?
g.prog.NAME = 'Thesaurus'
class TestClass:
no = 'Class'
way = 'this'
def main ():
L = thes() # Some local varibles
L.tc = TestClass() # We can also recurse to class attributes
L.l = list() # And recurse to indices too!
L.l.append('Some')
L.l.append('objects')
g.L = L # Easily make these locals global
# Here's the real magic. Creating output without a fight.
print '''
When programing python using %(prog.NAME)s, it is very
easy to access your %(L.l.1)s.
%(L.l.0)s people might say %(prog.NAME)s has no %(L.tc.no)s.

# If I was using a storage class, I must use hasattr() or an ugly eval.

If you find yourself programing with nested dictionaries often, fighting to

a dictionary that could act (sort of) like a class, Thesaurus may be for you.
I have a few critiques on the code. First, you might want to use
__getattribute__ instead of __getattr__. Otherwise you'll end up
running into bugs like this:
thes = Thesaurus()
thes.update = 'now'
thes.update
built-in method update of Thesaurus object at 0x01DB30C8
Hey, where'd my data go? The answer is that it is in the Thesaurus:
thes['update']
42
But it's not visible as an attribute because it is shadowed by the
dict methods. Using __getattribute__ instead of __getattr__ would
mean that those non-special methods simply wouldn't be visible at all.
Second, in __getitem__ you start a loop with for i in
range(len(l)):, and then you use i as an index into l several times.
It would be cleaner and more Pythonic to do for i, part in
enumerate(l):, and then you can replace every occurrence of l[i]
with part (or whatever you want to call that variable).
Third, also in __getitem__ you have this code:
if '.' not in key:
return dict.__getitem__(self, key)
l = key.split('.')
if isinstance(l[0], (dict, Thesaurus)):
a = self.data
else:
a = self
It's not clear to me what the isinstance call here is meant to be
testing for. The prior statements require key to be a string. If key
is a string, then by construction l[0] is also a string. So it seems
to me that the isinstance check here will always be False.
In any case, the key splitting here seems to be done primarily to
support the use of formatting placeholders like %(L.l.1)s in the
examples. I want to point out that this use case is already well
supported (I might even say better supported since it cleanly
distinguishes index elements from attributes with syntax) by the
str.format style of string formatting:
L = {'l': ['zero', 'one']}
There should be {L[l][1]}-- and preferably only {L[l][1]} --obvious way to
do it..format(L=L)
'There should be one-- and preferably only one --obvious way to do it.'
Lastly, you have several bare except clauses in the code. Bare
excepts are almost always incorrect. I appreciate that it's not easy
to predict exactly what exceptions might turn up here (although I
posit that for all of these, subsets of (TypeError, KeyError,
AttributeError, IndexError) are sufficient), but at the very minimum
you should specify except Exception, so that you're not
inadvertently catching things like SystemExit and KeyboardInterrupt.
Cheers and hope this is helpful,
Ian

As you can see this approach suffers from the same buffer problem as

get rid of the first data pair and add an extra measure command for

problem is there in Python and not in Octave and I also fear I'll get
more trouble when sending combined commands e.g. such as that to
create a staircase current
So my question is, how to modify the Python-code such that the first
data pair is indeed the first data pair

numofchar = int(raw_input())

usbkeith = open('/dev/usbtmc1','r+')
usbkeith.flush()
usbkeith.write(*IDN?\n)
It seems like a real leap of faith to be opening /dev/usbtmc1 as though it
were a file-oriented device. I've never heard of ANY instrument interface
implemented this way.
Where did you see example code that did that.
I found examples in the usbtmc kernel driver documentation (the
examples there are given in C):
http://www.home.agilent.com/upload/cmc_upload/All/usbtmc.htm?cc=BElc=dut
Have you tried to access /dev/usbtmc1 as though it were a serial device?
Yes, I did, as I used to do when communicating with rs232 devices. I
first tried to communicate to with the Keithley using cutecom but I
soon discovered you can't work that way because as soon as you open
the device it closes immediately thereafter. You really have to use
usbtmc (unfortunately) I'm missing the correct flushing commands to
do it correctly in Python...Maybe I should try to call the octave code
from within Python?

[issue15390] PEP 3121, 384 refactoring applied to datetime module
Robin Schreiber added the comment: I have updated the patch to work again with the current version of the _datetimemodule. Regarding the suggestion of separating PEP3121 and PEP384. It might be true that datetime and other modules do not benefit directly from PEP 384, however it is still a fact that the stdlib modules should be seen as a set of reference modules, that are all implemented in a way that complies with the implementation fo the xxmodules. I have talked with Martin von Löwis about this, and as far as I understood him correctly he also sees the PEP384 refactoring applied to the whole stdlib as a nessecary signal to other developers to refactor their modules accordingly. Anyway I am planning to start to commit all of the open changes that I have created during my GSOC in the next few months. So a decision regarding this separation concern might be helpful. :-) -- keywords: +patch Added file: http://bugs.python.org/file28274/_datetimemodule_pep3121-384_v3.patch ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue15390 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue16656] os.walk ignores international dirs on Windows
New submission from anatoly techtonik:
This critical bug is one of the reasons that non-English speaking communities
doesn't adopt Python as broadly as it happens in English world compared to
other technologies (PHP etc.).
# -*- coding: utf-8 -*-
import os
os.mkdir(u'Русское имя')
os.mkdir(u'English name')
for r, dirs, files in os.walk('.'):
print dirs
This gives:
['English name']

[issue16656] os.walk ignores international dirs on Windows
Jeremy Kloth added the comment: The problem exhibited is not coming from the os.walk() implementation, but from the use of a byte-string as the argument to it. The directories are created with unicode literals and therefore the argument must also be a unicode literal (u'.') for them to be shown. See the note in the listdir() documentation. As it stands, I suggest that this is closed as invalid, or at the minimum that it could be a documentation bug for walk() not also having a similar note as listdir(). -- nosy: +jkloth ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue16656 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue16656] os.walk ignores international dirs on Windows
R. David Murray added the comment:
Works for me without the u'.', too, though less usefully:
for r, dirs, files in os.walk('.'):
... print dirs
...
['\xd0\xa0\xd1\x83\xd1\x81\xd1\x81\xd0\xba\xd0\xbe\xd0\xb5
\xd0\xb8\xd0\xbc\xd1\x8f']
Maybe that doesn't work on Windows, though. I am, of course, assuming that
python3 does the right thing on Windows, but I can't imagine Victor would have
overlooked that.

[issue15207] mimetypes.read_windows_registry() uses the wrong regkey, creates wrong mappings
Dave Chambers added the comment: (I'm a windows dev type) I would say that there are 2 issues with relying on the registry: 1) Default values (ie. set by Windows upon OS install) are broken and MS never fixes them. 2) The values can be changed at any time, by any app. Thus the values are unreliable. If I were to code it from scratch today, I'd create a three-pronged approach: a) Hardcode a list of known types (fast reliable). b) Have a default case where unknown types are pulled from the registry. Whatever value is retrieved is likely better than returning e.g. application/octet-stream. c) When we neither find it in hardcoded list or in the registry, return a default value (e.g. application/octet-stream) For what it's worth, my workaround will be to have my app delete the HKCR\MIME\Database\Content Type\image/x-png regkey, thus forcing the original braindead mimetypes.py code to use HKCR\MIME\Database\Content Type\image/png And, for what it's worth, my patch is actually faster than the current mimetypes.py code because I'm not doing reverse lookups. Thus any argument about a difference in speed is moot. Arguments about the speed of pulling mimetypes from registry are valid. Another registry based approach would be to build a dictionary of mimetypes on demand. In this scenario, at startup, the dictionary would be empty. When python needs the mimetype for .png, on the 1st request it would cause a slow registry lookup for only that type but on all subsequent requests for the type it would use the fast value from the dictionary. Given that an app will probably use only a handful of mimetypes but will use that same handful over and over, such a solution would have the benefits of (a) not using hardcoded values (thus no ongoing maintenance), (b) performing slow stuff only on demand, (c) optimizing repeat calls, and (d) consuming zero startup time. I'll code his up run some timing tests if anyone thinks it's worthwhile. BTW, who makes the final determination as to if/when any such changes would be incorporated? -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue15207 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue16651] Find out what stdlib modules lack a pure Python implementation
Brett Cannon added the comment: So expat doesn't count as that literally wraps the expat library. Random also requires accessing the system randomization libraries to work properly so I don't think that is a candidate either. As for the compression libraries, those could be re-implemented, but I view those as wrappers around the libraries (same as the crypto stuff). I mean it doesn't have to be that way, but I'm trying to keep this framed in a tractable problem to start. So to summarize the non-contentious modules (including adding functools) in alphabetical order, that puts us at: array audioop binascii cjkcodecs csv functools itertools re struct I would be curious to see what frequency these modules are used to know what might be higher priority so that the least used modules could eventually be marked as CPython-specific. And to answer Chris' question, there is no need to be able to generate this from the docs until there is some PEP listing what modules must be implemented by a VM in order to considers its stdlib complete. And thanks for the help so far, everyone! -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue16651 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
