urllib equivalent for HTTP requests
Hello everyone,
I understand that urllib and urllib2 serve as really simple page
request libraries. I was wondering if there is a library out there
that can get the HTTP requests for a given page.
Example:
URL: http://www.google.com/test.html
Something like: urllib.urlopen('http://www.google.com/
test.html').files()
Lists HTTP Requests attached to that URL:
=> http://www.google.com/test.html
=> http://www.google.com/css/google.css
=> http://www.google.com/js/js.css

Python Windows release and encoding
Hi, I am working on Linux; a friend of mine sends to me python files from his Windows release. He uses the editor coming with the release; he runs his code from the editor by using a menu (or some F5 key I think). He doesn't declare any encoding in his source file; when I want to try his code, I have an error since he obviously uses non-ascii characters. As far as I can see, he uses utf8 without knowing it. I add the UTF8 declaration, run the code, and everything is fine. Then I tell him to add the utf-8 declaration; but now he has an error when running his file from the Windows editor. Finally, he told me he could run the file by declaring the latin-1 encoding. But I want to understand exactly: a) what is the encoding used by the editor coming in the Windows release? b) why doesn't he need to declare the encoding (I need it on Linux for the very same files)?

Keyboard hook in linux
Hi! I am working on a small console app for linux. The idea is to display some sensor values and the screen should update itself in, say, every 10 seconds. The user should have the possibly to change some configurations or gwt help by pressing different keys (like you can do when running e.g. 'top'). In other words: the program should NOT wait for the keypress (so input() is not the solution), but simply capture keypresses and act accordingly. If no key is pressed, the program should continue updating the screen. Practically I am looking for something similar than Pascal's "keypressed" function (http://www.freepascal.org/docs-html/rtl/crt/keypressed.html). The python code would be something like this: --- snip --- while True: if keypressed: ch=screen.getch() # From 'curses' # Test, if 'ch' is a valid key # Do what the user want read_sensors() update_screen() --- snip --- I have searched in the Web and in several tutorials (e.g. "Programming python"), but this seems to be a tricky one. The 'pyHook' library seems to offer a keyboard hook manager, but 'pyHook' is not available for linux :( IMHO, the 'curses' library offers no (direct) solution to this... Does anybody have an idea / a solution, how to capture keystrokes in linux? Kind regards, Kimmo -- http://mail.python.org/mailman/listinfo/python-list

Hi! Thanks, Michael, for your quick - and heplful - reply. 13.01.2013 18:46, Michael Torrie wrote: You're wrong. curses does offer a direct solution to this. Check the docs. Also here's a nice intro document for Python 3: http://docs.python.org/dev/howto/curses.html You are right :) The docs tell us (I somehow missed this when reading the doc last time): "It’s possible to change this behavior with the method nodelay(). After nodelay(1), getch() for the window becomes non-blocking and returns curses.ERR (a value of -1) when no input is ready. There’s also a halfdelay() function, which can be used to (in effect) set a timer on each getch(); if no input becomes available within a specified delay (measured in tenths of a second), curses raises an exception." This is actually funny: if you google for e.g. "capture keystrokes python", you will find masses of suggestions, none of them having this simple and elegant (i.e. python-like :) ) solution included.

Re: Help with chaos math extensions.
In case you missed it, I said I have windows XP. Windows XP pre-compiled python binaries are built on VS .NET 2003. In order to build extensions, you need the compiler the interpreter was built on, or at least that is what is reported to me by calling setup.py. If I was using linux, which I currently am not, it'd be a different story. Additionally, GCC isn't available for windows XP, only MinGW, the port, and I don't know that much about it to use it running on a Windows platform. Furthermore, I was asking for help on an extension, not an economical question about my programming environment.

print time.time()-t
this will crash it too
however I found that just opening up the interpreter and typing
import ctest
ctest.escapeMap(-1j,100,(50,50)) #50 yields much
smaller output than 500x500
it generates a 2d tuple fine. So the error seems really obscure to me,
and I don't understand it.

Re: Windows installer, different versions of Python on Windows
When you install Python it plug entries into the registry, so that when you go to install add-ons that are pre-compiled binaries, they look into the registry for the python directory. If you can find out how to manipulate the registry so that the binaries would recognize different installations, you'd be good to go. This would probably involve having copies of the same key with different values. > I would like to install several copies of Python 2.4.2 on my machine, > but it doesn't seem to be possible. > > If I allready has a version installed, the installer only gives the > options to: > > - change python 2.4.2 > - repair python 2.4.2 > - remove python 2.4.2 > > I would like to install different versions of Zope 3, and since it is > installed under a specific python version, the simplest solution would > be to install several Python versions, and install a different zope3 > version under each python install. > > Have I misunderstood something here? > > == Posted via Newsgroups.com - Usenet Access to over 100,000 Newsgroups == Get Anonymous, Uncensored, Access to West and East Coast Server Farms! == Highest Retention and Completion Rates!

Confused on Kid
Hey, so I heard about the TurboGears posting and decided to investigate. I watched some of their video on building a wiki in 20 minutes and was totally blown away because I'm used to python...straight python, not melding together 4 different APIs into one to blah blah. ANYWAY. I was investigating each subproject individually and could not, for the life of me figure out how Kid worked. I understand that it takes a well-formed XML document and transforms it, but I could not figure out where it transforms it, or how to transform a document. They have plenty of template examples, but I'm left say, "What do I do with this?" I know I can't just pop in it a browser because it has no sort of style sheet or anything so it would just render as an XML document. What do you do after you have a kid template? == Posted via Newsgroups.com - Usenet Access to over 100,000 Newsgroups == Get Anonymous, Uncensored, Access to West and East Coast Server Farms! == Highest Retention and Completion Rates!

Re: C Extension - return an array of longs or pointer?
All the veteran programmers out there can correct me, but the way I did
it in my extension was this:
static PyObject *wrap_doNumberStuff(PyObject* self, PyObject* args)
{
char* in = 0;
char* x = 0;
long* result = 0;
int i = 0;
PyObject* py = PyTuple_New()
int ok = PyArg_ParseTuple(args,"ss",&in, &x);
if(!ok) return NULL;
result = doNumberStuff(in,x):
len = sizeof(result)/sizeof(long)
for(i;i < len; i++)
PyTuple_SET_ITEM(py, i,Py_BuildValue("l",*result[i])
}
Simple enough idea...i'm not quite sure if I've done everything
correctly with the pointers, but I'm sure you can figure that out, the
algorithm is simple enough.

Re: C Extension - return an array of longs or pointer?
I'm sorry...I just woke up and forgot my C...must have left it in the
Coffee...Anyway, i made a few mistakes (can't initialize blank
tuple...function should return a value, lol).
static PyObject* wrap_doNumberStuff(PyObject* self, PyObject* args)
{
char* in = 0;
char* x = 0;
long* result = 0;
int i = 0;
PyObject* py = NULL;
if(!PyArg_ParseTuple(args,"ss",&in,&x) return NULL;
result = doNumberStuff(in,x);
len = sizeof(result)/sizeof(long);
py = PyTuple_New(len);
for(i; i < len; i++)
PyTuple_SET_ITEM(py, i, Py_BuildValue("l",*result[i]);
return py;
}
Additionally, the Python/C api in the docs tells you all of these nifty
little abstract layer functions that you can call from your extension.

Re: coloring a complex number
I'm not 100% sure about this, but from what it seems like, the reason
method B worked, and not method a is because class foo(complex) is
subclassing a metaclass. So if you do this, you can't init a meta class
(try type(complex), it equals 'type' not 'complex'. type(complex())
yields 'complex'), so you use the new operator to generator a class on
the fly which is why it works in method B. I hope that's right.

Need help vectorizing code

I didn't paste the whole function, note the ... before and after. I do use the values. I want to get rid of one of the loops so that the computation becomes O(D).

SSL certification fails / tweepy
Dear list members!
I have written I small python script for twitter mining utilising the
'tweepy' library. Since a couple of days I cannot use the script
anymore, due to a "ssl certificate verification failed" error. The
authentication with Twitter API succeess, but when I try to run the
following code:
--- snip ---
api=tweepy.API(auth) # 'auth' is my authentification token
print("Receiving network members for '", user_to_track, "' ... ")
network_members = []
#
# The user wants to get all followers of a twitter user
#
while True:
try:
for page in tweepy.Cursor(api.followers_ids, user_to_track).pages():
network_members.extend(page)
print("Current follower count: ", len(network_members))
if len(page)==5000: time.sleep(60)
break
except tweepy.TweepError as e:
# Did we exceed the rate limit?
if e.message[0]["code"]==88:
# Yes -> sleep for 15 minutes and then continue
print("Rate limit exceeded, sleeping for 15 minutes ...")
time.sleep(15*60)
continue
else:
# Something else went wrong -> break out from the loop!
print("Exception: ", e.message[0], " (", e.code[0], ") -->
interrupting, sorry!")
break
--- snip ---
the execution is broken with an "ŚSL_VERIFICATION_FAILED" error.
I have tried both python 2.7 and 3.x, no difference :( I have also
upgraded 'tweepy', no help.
I suspect this being somehow related to my current system, i.e. openSuSE
Tumbleweed. I tested the script on a ubuntu system and encountered no
problems... But I need to get the script running also with my openSuSE :)
Any ideas what could be causing this weird problem?
Thanks in advance!

Hi!

"SSL_VERIFICATION_FAILED" is an error which occurs when
an SSL ("https") connection is established. It happens when
the SSL certificate (of the server and/or client) does not contain

or its subject does not reference the connected entity or the
certificate chain cannot be verified.
Look for Python documentation on SSL verification to learn how to
properly set up things for successful verfication. Among others,
you will need have somewhere information about trusted root certificates.
Thanks, dieter, for your reply. I have now re-installed both certificate
packages and (open)ssl related python packages - and now it works!
I still wonder why openSuSE certificates are not working out-of-box with
python. Maybe some of the packages were not correctly installed...
Anyway, thanks for your quick reply - the issue is now solved :)

Integration using scipy odeint
Dear all I'm using Python 3.4.3. I am facing a problem in integrating using odeint solver. In the following code, tran is a function and in those are the variables which are arrays. These variables change their values with respect to time (the time which I pass to the function). I tried defining a loop inside the function, but Python throws an error saying float object not iterable. Please guide me how to solve this problem. #initial is an array containing initial values for the integration, dt is the time array with unequal time steps, which I have captured from other part of the code def tran(initial,dt): for i in dt: k1 [i] = 2.8e8 * math.exp(-21100/ta[i]) # k1,k2,k3 & k4 are constants which change according to temperature (ta), which in turn changes with respect to time. k2 [i] = 1.4e2 * math.exp(-12100/ta[i]) # ta changes its values according to dt, which is array. It runs from 0-6 with unequal time steps. k3 [i] = 1.4e5 * ta[i] * math.exp(-19680/ta[i]) # I've captured dt and all other arrays here from another loop, which is not of importtance. k4 [i] = 1.484e3 * ta[i] y = initial[0] z = initial[1] dn = (6*rho*initial[1]) dd = (math.pi*2000*initial[0]) ds = (dn/dd)**1/3 dydt = (166.2072*ta[i]*cca[i] - (1.447e13 * ta[i]**0.5 * rho**1/6 * y**1/6 * rho**1/6 * z**1/6 * 0.0832)) # cca,ta are arrays. y & z are 2 dependent variables dzdt = (k1[i]*ta[i]*cca[i]*12.011 + (21.2834*k2[i]*ta[i]*cca[i] * y**1/2 *ds) - (k3[i]*ta[i]*12.011*y*math.pi*ds**2 * cco[i]) - (phi*k4[i]*ta[i]*xo[i]*12.011*y*math.pi*ds**2)) return [dydt,dzdt] # dydt & dzdt are my final time integrated values initial = [0.01,1e-5] sol = odeint(tran, initial, dt) #this is my function call If I pass array in my function call, it says only length-1 can be converted to Python scalars.

numpy slice: create view, not copy
Hi, given an array: import numpy a = numpy.arange(100).reshape((10,10)) print a [[ 0 1 2 3 4 5 6 7 8 9] [10 11 12 13 14 15 16 17 18 19] [20 21 22 23 24 25 26 27 28 29] [30 31 32 33 34 35 36 37 38 39] [40 41 42 43 44 45 46 47 48 49] [50 51 52 53 54 55 56 57 58 59] [60 61 62 63 64 65 66 67 68 69] [70 71 72 73 74 75 76 77 78 79] [80 81 82 83 84 85 86 87 88 89] [90 91 92 93 94 95 96 97 98 99]] I'd like to create a new array that is a view of a, i.e. it shares data. If a is updated, this new array should be automatically 'updated'. e.g. the array west should be a view of a that gives the element at the left of location i,j in a. a[i,j] = west[i,j+1] west can be created using: a[:,range(-1,a.shape[1]-1)] As you can see, this also defines periodic boundaries (i.e. west[0,0] = 9) but it seems that this returns a copy of a, not a view. How can I change the slice definition in such a way it returns a view? Thanks in advance, Karel -- http://mail.python.org/mailman/listinfo/python-list
py and Dabo class in chi
I am organizing 3 python events in Chicago: 2 free, one cheap. 1st is really just an extended VFP users group meeting featuring Ed Leafe, one of the Dabo developers. I am getting a larger room to accommodate the python group too. The meeting is Nov 14 5:30pm in the loop: (not sure yet where, watch this page http://chipy.org/EdOnDabo ) There is some interest in an afternoon talk at 1:00 to 4:30. If I can get 5 or so people to commit to showing up, then Ed will talk then too. Probably worth staying for the evening presentation too - the Q/A will be worth as much as his presentation. I am hosting a 2 day mini event too: http://chipy.org/BootCampy - nothing like a fest. For this I am planing on spending a few $ on an instructor, which I have not found yet - I have some nibbles - but hoping to get a few more instead of just going with the first to respond. So if anyone is interested in either attending or instructing, please let me know. And of course, please forward this to any other list/group that may have some interest. If you are interested, or are near Chicago, please join the chipy list: http://mail.python.org/mailman/listinfo/chicago very low post rate - about 5 per day, mostly about the monthly meetings.

Search & Replace in MS Word Puzzle
Hi guys,
I wrote a script that works *almost* perfectly, and this lack of
perfection simply puzzles me.
I simply cannot point the whys, so any help on it will be appreciated.
I paste it all here, the string at the beginning explains what it does:
'''A script for MS Word which does the following:
1) Assigns all Hebrew italic characters "Italic" character style.
2) Assigns all Hebrew bold characters "Bold" character style.
2) Assign all English US characters "English Text" (can be regular,
Italic, or Bold)
'''
import win32com.client
#setting up shortcuts
word = win32com.client.Dispatch("Word.Application")
doc = word.ActiveDocument
find = doc.Content.Find
w=win32com.client.constants
#creating the needed styles if not there already
if "Italic" not in doc.Styles:
doc.Styles.Add("Italic",w.wdStyleTypeCharacter)
#"ItalicBi" is the same as "Italic", but for languages that go Right to
Left.
doc.Styles("Italic").Font.ItalicBi = True
print "Italic style was created"
if "Bold" not in doc.Styles:
doc.Styles.Add("Bold",w.wdStyleTypeCharacter)
doc.Styles("Bold").Font.BoldBi = True
print "Bold style was created"
if "English Text" not in doc.Styles:
doc.Styles.Add("English Text", w.wdStyleTypeCharacter)
doc.Styles("English Text").Font.Scaling = 80
print "English Text style was created"
if "English Text Italic" not in doc.Styles:
doc.Styles.Add("English Text Italic", w.wdStyleTypeCharacter)
doc.Styles("English Text Italic").BaseStyle = "English Text"
doc.Styles("English Text").Font.Italic = True
print "English Text Italic style was created"
if "English Text Bold" not in doc.Styles:
doc.Styles.Add("English Text Bold", w.wdStyleTypeCharacter)
doc.Styles("English Text Bold").BaseStyle = "English Text"
doc.Styles("English Text").Font.Bold = True
print "English Text Bold style was created"
#Search & Replacing Hebrew Italics
find.ClearFormatting()
find.Font.Italic = True
find.Format = True
find.LanguageID = w.wdHebrew
find.Replacement.ClearFormatting()
find.Replacement.Style = doc.Styles("Italic")
find.Execute(Forward=True, Replace=w.wdReplaceAll, FindText='',
ReplaceWith='')
print "Italic style was checked"
#Search & Replacing Hebrew Bolds
find.ClearFormatting()
find.Font.Bold = True
find.Format = True
find.LanguageID = w.wdHebrew
find.Replacement.ClearFormatting()
find.Replacement.Style = doc.Styles("Bold")
find.Execute(Forward=True, Replace=w.wdReplaceAll, FindText='',
ReplaceWith='')
print "Bold style was checked"
#Search & Replacing English Regulars
find.ClearFormatting()
find.LanguageID = w.wdEnglishUS
find.Font.Italic = False
find.Font.Bold = False
find.Replacement.ClearFormatting()
find.Replacement.Style = doc.Styles("English Text")
find.Execute(Forward=True, Replace=w.wdReplaceAll, FindText='',
ReplaceWith='')
print "English Text style was checked"
#Search & Replacing English Italics
find.ClearFormatting()
find.LanguageID = w.wdEnglishUS
find.Font.Italic = True
find.Replacement.ClearFormatting()
find.Replacement.Style = doc.Styles("English Text Italic")
find.Execute(Forward=True, Replace=w.wdReplaceAll, FindText='',
ReplaceWith='')
print "English Text Italic style was checked"
#Search & Replacing English Bolds
find.ClearFormatting()
find.LanguageID = w.wdEnglishUS
find.Font.Bold = True
find.Replacement.ClearFormatting()
find.Replacement.Style = doc.Styles("English Text Bold")
find.Execute(Forward=True, Replace=w.wdReplaceAll, FindText='',
ReplaceWith='')
print "English Text Bold style was checked"
print "We are done."
word.Visible=1
--Code end here
So generally speaking this script works quite nicely, BUT:
1. Despite this sort of conditions:
" if "Italic" not in doc.Styles: "
if this style already exists I get an error, and the program stops.
Any idea how can that be?...
2. The replacement of the English characters doesn't seem to work very
well. It either assigns all English characters "English Text Bold", or
"English Text Italic" and with no apparent reason.
?
3. The command
" word.Visible=1 "
doesn't work anymore. I say "anymore" because it used to work, but
later I ran "COM Makepy Utility" on "Microsoft Word 10 Object Library
(8.2)" and since then it stopped working. On Excel, for example, I
never ran Makepy and this commands works fine for it.
Any idea on this one?...
4. In the end of this long weekend I was pretty satisfied with my
script (even if not fully functioning) and used PY2EXE to make it an
.exe file so that I can use it in my work place. But alas, that .exe
file does not work because it doesn't recognize any of win32com client
constants. Such as "wdStyleTypeCharacter", or "wdEnglishUS"
How can I solve this one?
Advice will be very appreciated.

share function argument between subsequent calls but not between class instances!
Hi, given the following example class class Test: def f(self,a, L=[]): L.append(a) return L and the following statements a = Test() a.f(0) a.f(0) a.f(0) b = Test() b.f(0) this is the output I would like to have (i.e., expect) >>> a = Test() >>> a.f(0) [0] >>> a.f(0) [0, 0] >>> a.f(0) [0, 0, 0] >>> b = Test() >>> b.f(0) [0] But this is what I get: >>> a = Test() >>> a.f(0) [0] >>> a.f(0) [0, 0] >>> a.f(0) [0, 0, 0] >>> b = Test() >>> b.f(0) [0, 0, 0, 0] as you can see, the b.f method shares L with a.f.

ctree data
A friend needs to convert c-tree plus data to MySql. I can to the "to MySql part, but need some help with the "from c-tree." If I just wanted to get this done, I would hunt down the ODBC driver and use some MSy thing. But I am trying to hone my Python skills, but right now I am in over my head, thus this post. I think with a little boost I will be able to make it all come together. (well, little boost may be an understatement - I have no clue how close/far I am from what I need.) My searching around has come up with a few ways to use Python to read the data: 1. pull what I need from some other py code that uses c-tree: http://oltp-platform.cvs.sourceforge.net/oltp-platform/OLTPP/services/PythonScript/PythonTranslate.h?view=markup http://oltp-platform.cvs.sourceforge.net/oltp-platform/OLTPP/scripts/TestZipCodes.py?view=markup 12 a,b,c = ZipCode.Get() 13 print "Zip code is ", a 14 print "State is ", b 15 print "City is ", c I am sure this is what I want. I just haven't figured out where to start. 2. "Pyrex" to create Python bindings to C API with minimal C knowledge. I took C and did a few little utilities on my own in the 90's. plus I can make a tarball. today I am not sure I even qualify for "minimal." 3. the C API is present as a shared object (.so), use it from Python with ctypes. I have no idea what that means. 4. odbc - I am actually not thrilled about using the ctree odbc driver in any environment, because someone else who tried to use it on some other data a few years ago said it was flaky, and support was next to useless. 5, get someone who knows perl to do it using http://cpan.uwinnipeg.ca/htdocs/Db-Ctree/Db/Ctree.html - This just shows what lengths I am willing to go to. but I really don't want to start learning perl.

Thanks - now I can get to the real problem: client side join/order by :)
But I have already done it in MySql, so this should be the easy part...
Thanks again.

attribute save restore
Is there a more elegant way of coding this: x=o.p # save .p o.p=0 o.m() o.p=x # restore .p seems very push/pop to me - like there should be a way that doesn't need a var (x) or the save/set lines should be done in one command.

looking for ocbc example
I am sure this is what I want: http://www.python.org/topics/database/docs.html "The documentation for the PythonWin ODBC module." but it is 404. google isn't being nice. Anyone know where I can find some simple examples? I have used odbc in other environments, so just need to know what modules, and the lines to connect and execute a sql command.

Displaying future times

text wrapping help
I'm trying to text wrap a string but not using the textwrap module. I have 24x9 "matrix" and the string needs to be text wrapped according to those dimensions. Is there a known algorithm for this? Maybe some kind of regular expression? I'm having difficulty programming the algorithm. Thanks, Ryan -- http://mail.python.org/mailman/listinfo/python-list
Re: text wrapping help
Okay, I was a little vague in my last post...the matrix is like a Wheel of Fortune board and it knows nothing about newlines. After 24 characters it spills over onto the next line. Here is what I came up with: ## Wrap Text def wrap_text(in_str, chars_line): """ wrap text """ spaces = 0 new_str = "" tmp_str = "" while True: tmp_str = in_str[:chars_line] if tmp_str[chars_line-1].isspace(): new_str += tmp_str else: spaces = 0 for ch in reversed(tmp_str): if ch.isspace(): break spaces += 1 tmp_str = tmp_str[:chars_line-spaces] tmp_str += " " * spaces new_str += tmp_str in_str = in_str[chars_line-spaces:] if len(in_str) <= chars_line: new_str += " " + in_str break return new_str if __name__ == '__main__': sample_text = """Personal firewall software may warn about the connection IDLE makes to its subprocess using this computer's internal loopback interface. This connection is not visible on any external interface and no data is sent to or received from the Internet.""" print wrap_text(sample_text, 24) It doesn't even run but when I go through it interactively it seems okay. Once again, any help is appreciated. On Feb 28, 7:06 pm, "Ryan K" <[EMAIL PROTECTED]> wrote: > I'm trying to text wrap a string but not using the textwrap module.

Re: text wrapping help
That works great but I need to replace the newlines with 24-(the index
of the \n) spaces.

I tried it, and it worked better than pyodbc. (better is not exactly right. there was some weird bug in the ctree odbc driver, and the author of ceODBC gave me a workaround.)
