  • Decoding MIME (HTML+Attachments)

    - by MH
    I'm planning to write an application that should handle incoming mails. Basically it will act more like a ticketing system than a webmail, so I'm only interested in receiving emails, and not sending them. I have made a simple prototype that downloads mails and displays the text with downloadable attachments in a web page, but handling mails from Outlook and others is more complicated. I have looked at some of the open source ticketing systems out there, but most of the code is tied to the system and is hard to separate. Is there a library that understands "rich" mail and makes this job simpler? Preferably in Python, Java, Ruby or Perl. I'm also open to suggestions for any command line mail clients that can be used for this, since the system will not receive large amounts of mail and can afford to launch external processes.

  • Run command with no terminal output

    - by Insomaniacal
    Hello, I've searched around online, but can't find the answer to my question. What I want to do is run a command in pythong, using the subprocess module, and store the output in a variable. However, I do not want the command's output to be printed to the terminal. For this code: def storels(): a = subprocess.Popen("ls",shell=True) storels() I get the directory listing in the terminal, instead of having it stored in a. I've also tried def storels(): subprocess.Popen("ls > tmp",shell=True) a = open("./tmp") [Rest of Code] storels() This also prints the output of ls to my terminal. I've even tried this command with the somewhat dated os.system method, since running "ls tmp" in the terminal doesn't print ls to the terminal at all, but stores it in tmp. However, the same thing happens. I'm using python 2.6. Any suggestions? Thanks in advance!

  • Django development server serving css but not js

    - by Wisco crew
    I am developing a django (1.4) app on my local machine. I am running the built-in development server with python manage.py runserver. In base.html I have: <link href="{{ STATIC_URL }}bootstrap.css" rel="stylesheet" type="text/css" /> <script src="{{ STATIC_URL }}boostrap-dropdown.js" type="text/javascript"></script> boostrap.css loads just fine when I load a page, but bootstrap-dropdown.js is 404'd. They are sitting right next to each other in my static directory. Relevant parts of settings.py: STATIC_URL = '/static/' STATICFILES_DIRS = ( '/home/username/projects/projectname/static',) Debug is set to True. I have tried it both with and without the staticfiles_urlpatterns trick. Django can find one file in the directory but not the other? I think I'm going crazy.

  • Where should I declare a list of 5,000+ words?

    - by user647362
    I am writing a game in python in which I must periodically pull a random word from a list of words. When I prototyped my game I declared a word_list = ['cat','dog','rat','house'] of ten words at the top of one of my modules. I then use choice(word_list) to get a random word. However, I must must change this temporary hack into something more elegant because I need to increase the size of the word list to 5,000+ words. If I do this in my current module it will look ridiculous. Should I put all of these words in a flat txt file, and then read from that file as I need words? If so, how would I best do that? Put each word an a separate line and then read one random line? I'm not sure what the most efficient way is.

  • downloading full page text from a web domain

    - by user362808
    Howdy, folks! First time here -- thought I'd field a question on behalf of a coworker. Somebody in my lab is doing a content analysis (e.g. reading an article or transcript line by line and identifying relevant themes) of the web presences of various privatized neuroimaging centers (e.g. http://www.canmagnetic.com/). She's been c/ping entire site maps by hand, and I know I could slap something together with Python to follow links and dump full text (with line numbers) for her, but I've never actually done anything quite like this. Any ideas for how I'd get started? Cheers, -alex

  • can this code be shortened or improved?

    Can this be shortened/improved? I'm trying to make a password checker in python. Could the if's be put into a for loop? And if so, how? pw = input("Enter password to test: ") caps = sum(1 for c in pw if c.isupper()) lower = sum(1 for c in pw if c.islower()) nums = sum(1 for c in pw if c.isnumeric()) scr = ['weak', 'medium', 'strong'] r = [caps, lower, nums] if len(pw) < 6: print("too short") elif len(pw) > 12: print("too long") if caps >= 1: if lower >= 1: if nums >= 1: print(scr[2]) elif nums < 1: print("your password is " + scr[1]) elif lower < 1: print("your password strength is " + scr[0]) elif caps < 1: print("your password strength is " + scr[1]) Thanks for any suggestions :D

  • Any efficient way to read datas from large binary file?

    - by limi
    Hi, I need to handle tens of Gigabytes data in one binary file. Each record in the data file is variable length. So the file is like: <len1><data1><len2><data2>..........<lenN><dataN> The data contains integer, pointer, double value and so on. I found python can not even handle this situation. There is no problem if I read the whole file in memory. It's fast. But it seems the struct package is not good at performance. It almost stuck on unpack the bytes. Any help is appreciated. Thanks.

  • One input file to multiple output files

    - by user1265669
    I found some helpful stuff on this site but my input file is different from the examples already posted and I cannot make the leap in an efficient manner. My input file looks like this: sample_dude data1 data2 data3 data4 sample_lady data5 data6 data7 data8 sample_dude data9 data10 data11 data12 sample_child data13 data14 data15 data16 I want to create a separate file for each sample with all the data columns. For example, one file would be called sample_dude.txt and look like this: data1 data2 data3 data4 data9 data10 data11 data12 There is an unknown number of samples but always just four data columns. Any help greatly appreciated. Thank you. PS: I'm trying to do this in python.

  • SQLite Queries for dates

    - by user2909616
    I have a SQLite data base which I am pulling data for a specific set of dates (lets say 01-01-2011 to 01-01-2011). What is the best way to implement this query into SQL. Ideally I would like the following line to run: SELECT * FROM database where start_date < date_stamp and end_date date_stamp This obviously does not work when I store the dates as strings. My solution (which I think is messy and I am hoping for another one) is to convert the dates into integers in the following format: YYYYMMDD Which makes the above line able to run (theoretically). IS there a better method? Using python sqlite3 Would the answer be any different if I were using SQL not SQLite

  • How do I use udev to find info about inserted video media (e.g. DVDs)

    - by Daniel
    I'm trying to port an application from using HAL to using pure udev. It is written in python and will use the gudev library, though I would love to see examples in any language. I'm able to get all attached video devices (such as cameras) via: import gudev client = gudev.Client(["video4linux"]) for device in client.get_devices(): print device.get_sysfs_attr("name"), device.get_device_name() This prints out something like: USB2.0 UVC WebCam /dev/video0 I am also able to get a list of block devices, but how can I: Tell if it is a CD/DVD drive? Tell if media is currently inserted if the drive supports removable media? Tell what the name/label of the media is (e.g. FUTURAMAS1 for a DVD)? The original code I am trying to port over is located at http://github.com/danielgtaylor/arista/blob/045a4d48ebfda44bc5d0609618ff795604ee134f/arista/inputs.py Any and all help would be greatly appreciated!

  • What is the best way to start learning how to program?

    - by Joe K
    I'm very new to programming, but it has always interested me. I've tried to learn a couple of times except I don't know where to begin. What's a good language to learn first? What is a good website that can help me learn it? I once partitioned my hard drive and installed Ubuntu in an attempt to learn Python, but I was overwhelmed. I didn't know where to start or what to do. All suggestions, feedback, comments are welcome.

  • Reorganized JSON

    Need to be reorganized JSON into a new structure.

  • Include upper bound in range()

    - by Jull
    How can I include the upper bound in range() function? I can't add by 1 because my for-loop looks like: for x in range(1,math.floor(math.sqrt(x))): y = math.sqrt(n - x * x) But as I understand it will actually be 1 < x < M where I need 1 < x <= M Adding 1 will completely change the result. I am trying to rewrite my old program from C# to Python. That's how it looked in C#: for (int x = 1; x <= Math.Floor(Math.Sqrt(n)); x++) double y = Math.Sqrt(n - x * x);

  • PySide 1.0.0 beta 2, le support complet des interfaces déclaratives arrive dans ce bindind LGPL Python de Qt

    Voici donc sortie la deuxième beta de PySide, le binding Python de Qt initié par Nokia, dont la principale différence avec le binding historique, PyQt, réside dans la licence : PySide est disponible sous LGPL, une licence moins restrictive que la GPL employée par PyQt. Ainsi, un binding Python de Qt peut être utilisé pour des développements propriétaires sans obligation de payer une licence commerciale. La première version beta de PySide (la bien dénommée beta 1) apportait un grand changement par rapport aux versions précédents (0.4.2 et avant) : un changement dans l'ABI (Application Binary Interface), ce qui, pour rester en dehors des détails techniques, obligeait à recompiler toute application se basant sur PySide (notamment le module Python). Cependant, ainsi, le projet ...

  • What if we run out of stack space in C# or Python?

    - by dotneteer
    Supposing we are running a recursive algorithm on a very large data set that requires, say, 1 million recursive calls. Normally, one would solve such a large problem by converting recursion to a loop and a stack, but what if we do not want to or cannot rewrite the algorithm? Python has the sys.setrecursionlimit(int) method to set the number of recursions. However, this is only part of the story; the program can still run our of stack space. C# does not have a equivalent method. Fortunately, both C# and Python have option to set the stack space when creating a thread. In C#, there is an overloaded constructor for the Thread class that accepts a parameter for the stack size: Thread t = new Thread(work, stackSize); In Python, we can set the stack size by calling: threading.stack_size(67108864) We can then run our work under a new thread with increased stack size.

  • Syncing WM6 <-> Evolution.... opensync-module-python missing?

    - by luri
    I'm trying to install opensync-plugin-synce to sync my wm6 phone with Evolution, but when I try (from synaptic, also with ap-get), is: Depende: opensync-module-python but it is not installable In fact, I haven't found opensync-module-python in repositories. Any hint? Is there any way to sync WM6 and Evolution (preferably without intermediate online syncs as Gmail, for instance)? Update: opensync-module-python exists in the repositories for previous versions of Ubuntu (mine is 10.10).... could I install it from there or would I ruin something? Update: should I mark this as impossible? Seems to be no way to sync WM6 phone with Evolution right now....

Hi all,now I'm already can convert text files to excell file by python using script that was given from user named Rami Helmy.A big thanks for him.But now,That script will produce more than one excell files depends on the number of '|' from the text files.Beside that,That script also can only convert one text files.I a going to convert all text files without state the name of text files.Therefore,I am looking such a way on how to this script going to: output only one excell file convert all .txt files from the directory that was given from user. output excell's file name are automaticly copied from the file name of text files. I am new in python,hopefully someone can help me to solve my problems.Thank You.. done all the task,but there was something that I'm confused.. that output excell files contains an "square" symbol like this: then, how can I ensure that there is no square symbol like that after I convert from text files to excell? thank you...

  • How do I correctly install dulwich to get hg-git working on Cygwin?

    - by Erik Vold
    I have a similar issue as in this issue, but in my case I am trying to use cygwin. First I followed the instructions here, and I ran: $ easy_install hg-git The I created ~/.hgrc, with: [extensions] hgext.bookmarks = hggit = Then when I typed 'hg' at a command prompt, I'd see: "* failed to import extension hggit: No module named hggit" So I did a search for "hggit" and found /cygdrive/c/Python26/Lib/site-packages/hg_git-0.2.1-py2.6.egg/hggit, so I updated .hgrc: [extensions] hgext.bookmarks = hggit = /cygdrive/c/Python26/Lib/site-packages/hg_git-0.2.1-py2.6.egg/hggit Then when I type 'hg' I get "No module named dulwich.errors" If you read this question, it's the same problem. In python shell I cannot import dulwich: >>> import dulwich Traceback (most recent call last): File "<stdin>", line 1, in <module> ImportError: No module named dulwich I checked out my easy-install.pth and it does contain the dulwich egg: import sys; sys.__plen = len(sys.path) ./hg_git-0.2.1-py2.6.egg ./dulwich-0.5.0-py2.6-win32.egg import sys; new=sys.path[sys.__plen:]; del sys.path[sys.__plen:]; p=getattr(sys,'__egginsert',0); sys.path[p:p]=new; sys.__egginsert = p+len(new) So how can I fix this so that import dulwich works, which should fix my problem using hg-git I assume..

  • PyGTK/GIO: monitor directory for changes recursively

    - by detly
    Take the following demo code (from the GIO answer to this question), which uses a GIO FileMonitor to monitor a directory for changes: import gio def directory_changed(monitor, file1, file2, evt_type): print "Changed:", file1, file2, evt_type gfile = gio.File(".") monitor = gfile.monitor_directory(gio.FILE_MONITOR_NONE, None) monitor.connect("changed", directory_changed) import glib ml = glib.MainLoop() ml.run() After running this code, I can then create and modify child nodes and be notified of the changes. However, this only works for immediate children (I am aware that the docs don't say otherwise). The last of the following shell commands will not result in a notification: touch one mkdir two touch two/three Is there an easy way to make it recursive? I'd rather not manually code something that looks for directory creation and adds a monitor, removing them on deletion, etc. The intended use is for a VCS file browser extension, to be able to cache the statuses of files in a working copy and update them individually on changes. So there might by anywhere from tens to thousands (or more) directories to monitor. I'd like to just find the root of the working copy and add the file monitor there. I know about pyinotify, but I'm avoiding it so that this works under non-Linux kernels such as FreeBSD or... others. As far as I'm aware, the GIO FileMonitor uses inotify underneath where available, and I can understand not emphasising the implementation to maintain some degree of abstraction, but it suggested to me that it should be possible. (In case it matters, I originally posted this on the PyGTK mailing list.)
