  • How to determine if the variable is a function in Python?

    - by bodacydo
    Since functions are values in Python, how do I determine if the variable is a function? For example: boda = len # boda is the length function now if ?is_var_function(boda)?: print "Boda is a function!" else: print "Boda is not a function!" Here hypothetical ?is_var_function(x)? should return true if x is a callable function, and false if it is not. Please advise! Thanks, Boda Cydo.

  • Writing your own Makefile for OpenBSD ports

    - by The_dude_man
    I have an OpenBSD box running Python 2.6. I want to install py-setuptools, but that package is built against 2.5. I was curious as to what the Makefile for py-setuptools [Someone with rep, fix me please][http://www.openbsd.org/cgi-bin/cvsweb/ports/devel/py-setuptools/Makefile?rev=1.13;content-type=text%2Fx-cvsweb-markup ] looks like, to see if it mentioned anything about Python 2.5 as a dependency. I did not find anything version-dependent. I typed make install in /usr/ports/devel/py-setuptools on a whim, and it blew up because of failed missing Python 2.5 dependency. That is expected. My question is, How do I modify the Makefile to build against Python 2.6 ? I came across this in the man pages [please fix me][http://www.openbsd.org/cgi-bin/man.cgi?query=port-modules&sektion=5&arch=&apropos=0&manpath=OpenBSD+4.6#CORE+MODULES] , but I am still clueless how to specify what version to build against. Also, I dont see anything that actually installs the egg.

  • Quitting dozens of the same process in OS X Terminal

    - by Artur Sapek
    Whenever I'm testing a python class I'm working on, I initiate and re-initiate python a lot to refresh the updates I make to the code. When I close the Terminal window later, I get a window that says I am about to quit a LOT of running instances of python. Is this a bug on terminal's part, or am I really running all those? I Ctrl-Z out of it each time but it always says [8]+ Stopped Python where the 8 is incremental and often gets into the 20's and 30's. Am I doing something stupid?

  • How get Win32_OperatingSystem.LastBootUpTime in datetime format

    - by chekalin-v
    I have been trying to get LastBootUpTime using Win32_OperatingSystem class (WMI). HRESULT hr = pEnumerator->Next(WBEM_INFINITE, 1, &pclsObj, &uReturn); if(0 == uReturn) { break; } VARIANT vtProp; // Get the value of the Name property hr = pclsObj->Get(L"LastBootUpTime", 0, &vtProp, 0, 0); VariantClear(&vtProp); I want to write this time to CTime or COleDateTime variable. But variable vtProp has BSTR type and look like 20100302185848.499768+300 Also any datetime property of any WMI class have BSTR type How can I put datetime property of WMI class to CTime?

  • pip install fails on guest Linux Mint 15

    - by synergetic
    On my Windows 7 PC, I installed VMware VM for Linux Mint 15. Windows PC is behind corporate firewall /proxy server. Now inside Linux I issued: sudo apt-get install python-virtualenv Then created ~/projects folder and python virtual environment: mkdir projects cd projects virtualenv venv Then activated my virtual env: . venv/bin/activate So far no problem. Then tried to install python libraries, for example markupsafe: pip install markupsafe It throws an error: Cannot fetch index base URL https://pypi.python.org/simple/ Could not find any downloads that satisfy the requirement markupsafe No distributions at all found for markupsafe Storing complete log in /home/me/.pip/pip.log Inside pip.log I found: <urlopen error [Errno 104] Connection reset by peer> Installing any other library throws similar error. What's wrong here?

  • Where do you use generators feature in your python code?

    - by systempuntoout
    I have studied generators feature and i think i got it but i would like to understand where i could apply it in my code. I have in mind the following example i read in "Python essential reference" book: # tail -f def tail(f): f.seek(0,2) while True: line = f.readline() if not line: time.sleep(0.1) continue yield line Do you have any other effective example where generators are the best tool for the job like tail -f? How often do you use generators feature and in which kind of functionality\part of program do you usually apply it?

  • urllib2 in Python 2.6.4: Any way to override windows hosts file?

    - by mikez302
    I am using the urllib2 module in Python 2.6.4, running in Windows XP, to access a URL. I am making a post request, that does not involve cookies or https or anything too complicated. The domain is redirected in my C:\WINDOWS\system32\drivers\etc\hosts file. However, I would like the request from urllib2 to go to the "real" domain and ignore the entry in the hosts file. Is there any easy and practical way to do this?

  • What (pure) Python library to use for AES 256 encryption?

    - by Daren Thomas
    I am looking for a (preferably pure) python library to do AES 256 encription and decryption. This library should support the CBC cipher mode and use PKCS7 padding according to the answer to an earlier question of mine. The library should at least work on Mac OS X (10.4) and Windows XP. Ideally just by dropping it into the source directory of my project. I have seen this by Josh Davis, but am not sure about how good it is and if it does the required CBC cipher mode... Scanning the source suggests it doesn't

  • How to start process as a daemon?

    - by Markus Johansson
    I have created a service which consists of a web fronted (nginx), python runner glue handler (uwsgi) and my own python code (fetcher). I have made a script (deploy.sh) to start the difference services: nginx uwsgi --ini inifie.ini python fetcher.py & disown My question is regarding how I start my python daemon. I want it to run in the background. It should not print anything to my current terminal. If I add "print" calls to my fetcher script I currently see them in the terminal window. So my question is: how do I start my fetcher.py script as a daemon?

  • I have a list of names, some of them are fake, I need to use NLP and Python 3.1 to keep the real nam

    - by Sho Minamimoto
    I have no clue of where to start on this. I've never done any NLP and only programmed in a Python 3.1, which I have to use. I'm looking at the site http://www.linkedin.com and I have to gather all of the public profiles and some of them have very fake names, like 'aaaaaa k dudujjek' and I've been told I can use NLP to find the real names, where would I even start?

  • Installing Trac on Windows under Apache 2.2?

    - by Warren P
    Trac is a python-powered bug-tracking and project-management app. According to Trac's wiki, there are several options for installing Trac, a standalone server (tracd), or under a dedicated webserver using one of these options: FastCGI - Not available on windows. mod_wsgi - No version of mod_wsgi available for Apache 2.2.22 and Python 2.7.3-amd64 that actually runs on my system! mod_python - no longer recommended, as mod_python is not actively maintained anymore) CGI -should not be used, as the performance is far from optimal) That leaves me with zero ways to run Trac on Windows. Apache 2.2.22 with ModWSGI loading, crashes the Apache2.2 service on startup without any error logs. Disabling the line in the apache configuration to load mod_wsgi restores sanity. I just want an installation of Trac on windows with Authentication enabled. I am unable to get authenetication to work using basic tracd like this: tracd -p 8000 --basic-auth="c:\tmp,c:\tmp\Passwords.md5.txt,mycompany" c:\tmp\RootFolder And I am unable to get Mod_WSGI installed. I'm going to keep trying to figure out a combination that works, I suspect I should have installed 32 bit python instead of 64 bit python, to start with. Did I do wrong to install Python 64 bit 2.7.3? I tried again with all 32 bit components, and still can't get MOD_WSGI to work with apache 2.2.22. I'm going to try to compile mod_wsgi myself with Visual C++ Express 2010, but it seems to me that it ought to be easier than this to get Trac running on windows, with authentication. Is there a way to run Trac on Windows, under Apache, with authentication? The last "Trac on windows" article died in 2008, leaving only this internet archive link for "Trac on windows" setup.
