  • permission errors with python/django

    - by tipu
    Error can be seen here: http://djaffry.selfip.com:8080/ If i go to the folder /srv/twingle/search and do ls -l I get -rwxrwxrwx 1 root root 65142784 May 26 20:28 words.db I gave it 777 access (absolutely unsafe, I know, but I thought it would atleast work) any idea what can be the permissions problem? Edit: A very strange problem is that the code doesn't crash once every few refreshes.. then goes back to crashing

  • Organizing a random list of objects in Python.

    - by Saebin
    So I have a list that I want to convert to a list that contains a list for each group of objects. ie ['objA.attr1', 'objC', 'objA.attr55', 'objB.attr4'] would return [['objA.attr1', 'objA.attr55'], ['objC'], ['objB.attr4']] currently this is what I use: givenList = ['a.attr1', 'b', 'a.attr55', 'c.attr4'] trgList = [] objNames = [] for val in givenList: obj = val.split('.')[0] if obj in objNames: id = objNames.index(obj) trgList[id].append(val) else: objNames.append(obj) trgList.append([val]) #print trgList It seems to run a decent speed when the original list has around 100,000 ids... but I am curious if there is a better way to do this. Order of the objects or attributes does not matter. Any ideas?

  • uWSGI and python virtual env

    - by user27512
    I'm trying to use uWSGI with a virtual env in order to use the Trac bug tracker on it. I've installed system-wide uwsgi via pip. Next, I've installed trac in a virtualenv $ virtualenv venv $ . venv/bin/activate $ pip install trac I've then written a simple uWSGI configuration script: [uwsgi] master = true processes = 1 socket = localhost:3032 home = /srv/http/trac/venv/ no-site = true gid = www-data uid = www-data env = TRAC_ENV=/srv/http/trac/projects/my_project module = trac.web.main:dispatch_request But when I try to launch it, it fails: $ uwsgi --http :8000 --ini /etc/uwsgi/vassals-available/my_project.ini --gid www-data --uid www-data ... Set PythonHome to /srv/http/trac/venv/ ... *** Operational MODE: single process *** ImportError: No module named trac.web.main unable to load app 0 (mountpoint='') (callable not found or import error) I think uWSGI isn't using the virtual env. When inside the virtual env, I can import trac.web.main without having an ImportError. How can I do that ? Thanks

  • Will modules installed by insmod command persist after rebooting?

    - by apache
    There is how the book I'm reading describe the insmod utility: The program loads the module code and data into the kernel, which, in turn, performs a function similar to that of ld, in that it links any unresolved symbol in the module to the symbol table of the kernel. Unlike the linker, however, the kernel doesn’t modify the module’s disk file, but rather an in-memory copy. It looks like it won't persist since it's in-memory, but I'm not sure.

  • How safe is it to rely on thirdparty Python libs in a production product?

    - by skyler
    I'm new to Python and come from the write-everything-yourself world of PHP (at least this is how I always approached it). I'm using Flask, WTForms, Jinja2, and I've just discovered Flask-Login which I want to use. My question is about the reliability of using thirdparty libraries for core functionality in a project that is planned to be around for several years. I've installed these libraries (via pip) into a virtualenv environment. What happens if these libraries stop being distributed? Should I back up these libraries (are they eggs)? Can I store these libraries in my project itself, instead of relying on pip to install them in a virtualenv? And should I store these separately? I'm worried that I'll rely on a library for core functionality, and then one day I'll download an incompatible version through pip, or the author or maintainer will stop distributing it and it'll no longer be available. How can I protect against this, and ensure that any thirdparty libraries that I use in my projects will always be available as they are now?

  • Which Language Next? Python? Ruby? [closed]

    - by Ryan Craig
    I am a beginning Webmaster (relatively), with 2+ years of php experience. I also have some java training and a bit of .net. My company is now close to redeveloping the website that I work on, which is coded primarily in php, but has some poorly-written .net in part as well (it's confusing and ill-planned, but I didn't make any of those decisions. Can anyone say action-oriented .net and JScript?). So, I'm trying to decide which language I should learn next to quickly develop a new site. I will probably just redevelop it at first in php because I'm very comfortable with it. However, I'd like to migrate in the next year to something newer and more forward-thinking. This being said, .net is out of the question a little bit. We need cheap developers who are fast and can get pages up quickly. In this part of the country, part-time .net developers are hard to find. So, we need something that will be pretty standard in the next few years, but we have some .net SOAP 1.1 APIs that we use on our actual service (separate from the corporate website), that we will need to integrate part of the site with. Developing with php and SOAP is much more difficult than doing the same thing. So, I may have to develop the API collaborative part in .net just to be easy, and then I'd like to use something else that is fast, flexible, forward thinking, and will be relatively standard and easy to find developers for. So, any ideas? Python and Django? Ruby on Rails? Another framework? Thanks for your thoughts. Sorry, I know this was long, but it's all very convoluted and confusing so I needed to be slightly long-winded.

  • Installing Django on Shared Server: No module named MySQLdb?

  • Python 3.1, trying to unescape html/unicode/xml characters

    - by Sho Minamimoto
    I found my problem here, but there is only an answer for Python 2.6. Basically, I need to unescape strings such as this: 'a altieri_joão' to show the proper characters. http://stackoverflow.com/questions/990169/how-do-convert-unicode-escape-sequences-to-unicode-characters-in-a-python-string I need to do this in 3.1, but when I try print (u'a altieri_jo&#xe3;o') if gives me invalid syntax. And when I try name.decode('latin-1') it says 'str' has no method 'decode'.

  • Potential annoyances of tab delimited Python source?

    - by user86432
    I want to start a new project, and I want this to be my first Python project. I was looking through the style guide, http://www.python.org/dev/peps/pep-0008/, which "strongly recommends" using a 4-spaces indentation style for new projects. But I just hate this idea! In my opinion, tabs are better for this purpose. What annoyances could crop up one day if another developer wanted to work on my tab-delimited files?

  • Arguments, local variables, and global variables coding convention in Python

    - by prosseek
    In python, there is no way to differentiate between arguments, local variables, and global variables. The easy way to do so might be have some coding convention such as Global variables start with _ and capital letter arguments end with with _ _Gvariable = 10 def hello(x_, y_): z = x_ + y_ Is this a Pythonian way to go? I mean, is there well established/agreed coding-standards to differentiate them in python?

  • Kill process by name in python

    - by user353064
    Hello, I'm trying to kill a process (specifically iChat) using python. I know how to use the command: ps -A | grep iChat Then: kill -9 PID However, I'm not exactly sure how to translate these commands over to python. My guess is that it's not very difficult but I just don't know. Any help would be greatly appreciated!

  • Set attributes from dictionary in python

    - by Oscar Reyes
    Is it possible to create an object from a dictionary in python in such a way that each key is an attribute of that object? Something like this: dict = { 'name': 'Oscar', 'lastName': 'Reyes', 'age':32 } e = Employee( dict ) print e.name # Oscar print e.age + 10 # 42 I think it would be pretty much the inverse of this question: Python dictionary from an object's fields

  • Python Class which checks input before passing to console (C) program

    - by Joseph Melettukunnel
    Hello, We are asked to write a web-frontend (in python) for a very complex (and old) console application, written in C. Since we have no access to the C Source Code, and we assume that there might be some unsafe methods, we'd like to check the input which will the passed to the console application. WebClient - Python Module - Console Application Do you have any suggestions or tips what we should check for? Right now we are only limiting the string length and filtering some (program specific) unallowed keywords. Thanks, Joseph EDIT: Will remove strings like %s because of format string attacks
