  • Is there an IDE that provides code completion for Python

    - by Justin Walgran
    I am quite fond of the Intellisense code completion baked into Microsoft Visual Studio. I find that I only type 2 to 4 characters of any given keyword which drasticaly speeds up my coding. Now that I have been spending time writing some Python code I find myself reaching for ctrl+space. Are there any IDEs that support code completion in Python? I do my python development on a Mac so an OS x tool would be preferable. It seems like the doc string property of Python methods is a perfect match for inline API discovery.

  • Python MySQLdb LOAD LOCAL INFILE problems

    - by belvoir
    The problem is a simple one. When I execute the following I get different results depending on whether I run it from the MySQL console and from inside a Python Script using MySQLdb: LOAD DATA LOCAL INFILE '/tmp/source.csv' INTO TABLE test FIELDS TERMINATED BY '|' IGNORE 1 LINES; Console gives the following results: Records: 35002 Deleted: 0 Skipped: 0 Warnings: 0 Python (via .info()) returns the following: Records: 34977 Deleted: 0 Skipped: 0 Warnings: 8 So in summary, same source file, same SQL request, different results. From the console I can 'SHOW WARNINGS' an get a better handle on which records are causing the problems and why but from Python I can't idenitify how to do this or more importantly what the cause of the problem could be. Any suggestions? MySQL Server '5.1.41-3ubuntu12.1' Python '2.6.5' Tables are MyISAM

  • Is it possible to use re2 from Python?

    - by flow
    i just discovered http://code.google.com/p/re2, a promising library that uses a long-neglected way (Thompson NFA) to implement a regular expression engine that can be orders of magnitudes faster than the available engines of awk, Perl, or Python. so i downloaded the code and did the usual sudo make install thing. however, that action had seemingly done little more than adding /usr/local/include/re2/re2.h to my system. there seemed to be some `*.a file in addition, but then what is it with this *.a extension? i would like to use re2 from Python (preferrably Python 3.1) and was excited to see files like make_unicode_groups.py in the distro (maybe just used during the build process?). those however were not deployed on my machine. how can i use re2 from Python?

  • Problem in printing array of char pointer passing from Python

    My following C code works quite well, till my Python code trying to pass an array of char pointer to it. The output I obtain is The file_name is python-file Another 3 string is not being printed out. Anything I had missed out? C Code #include <iostream> #include "c_interface.h" int foo(const char* file_name, const char** names) { std::cout << "The file_name is " << file_name << std::endl; while (*names) { std::cout << "The name is " << *names << std::endl; names++; } return 0; } /* int main() { const char *c[] = {"123gh", "456443432", "789", 0}; foo("hello", c); getchar(); } */ Python Code #!c:/Python27/python.exe -u from ctypes import * name0 = "NAME0" name1 = "NAME1" name2 = "NAME2" names = ((c_char_p * 1024) * 4)() names[0].value = name0 names[1].value = name1 names[2].value = name2 names[3].value = 0 libc = CDLL("foo.dll") libc.foo("python-file", names)

  • Python, Ruby, and C#: Use cases?

    - by thaorius
    Hi everyone. For as long as I can remember, I've always had a "favorite" language, which I use for most projects, until, for some particular reason, there is no way/point on using it for project XYZ. At that point, I find myself rusty (and sometimes outdated) on other languages+libraries+toolchains. So I decided, I would just use some languages/libs/tools for some things, and some for other, effectively keeping them fresh (there would obviously be exceptions, I'm not looking for an arbitrary rule set, but some guidelines). I wanted an opinion on what would be your standard use cases (new projects) for Python, Ruby, and C# (Mono). At the moment, I have time like this:Languages: C#: Mid-Large Sized Projects (mainly server-side daemons) High Performance (I hardly ever need C's performance, but Python just doesn't cut it) Relatively Low Footprint (vs the JVM, for example) Ruby: Web Applications Python: General Use Scripts (automation, system config, etc) Small-Mid Sized Projects Prototyping Web Applications About Ruby, I have no idea what to use it for that I can't use Python for (specially considering Python is more easily found installed by default). And I like both languages (though I'm really new to Ruby), which makes things even worse. As for C#, I have not used a Windows powered computer in a few years, I don't make things for Windows computers, and I don't mind waiting for Mono to implement some new features. That being said, I haven't found many people on the internet using it for server-sided *nix programming (not web related). I would appreciate some insight on this too. Thanks for your time.

  • How do Python and PHP compare for ecommerce?

    - by Ibn Saeed
    If I were to start an ecommerce store, which language would you suggest I start with? Python or PHP? And would it be wise to use Python for an ecommerce site in favor of PHP? PHP has lots of shopping carts, both open source and commercial. Is Python the future of Web Development ? Edit: I would like to clear out that i am not asking for Shopping carts solutions and links to them.

  • Want procmail to run a custom python script, everytime a new mail shows up

    - by Maddy
    I have a pretty usual requirement with procmail but I am unable to get the results somehow. I have procmailrc file with this content: :0 * ^To.*@myhost | /usr/bin/python /work/scripts/privilege_emails_forward.py Wherein my custom python script(privilege_emails_forward.py) will be scanning through the email currently received and do some operations on the mail content. But I am unable to get the script getting executed at the first shot(let alone scanning through the mail content). Is this a correct way of invoking an external program(python) as soon as new mail arrives? And how does my python program(privilege_emails_forward.py) will receive the mail as input? I mean as sys.argv or stdin????

  • Python 3.1 twitter post with installed library,

    - by Andrew
    I'd like to be able to post twitter messages from python 3.0. None of the twitter API I have looked at support python 3.1. Since the post proceedure only requires this : JSON: curl -u username:password -d status="your message here" http://api.twitter.com/1/statuses/update.json I was wondering if it is possible with the standard libraries to format this so a message could be sent. My head says it should be possible.

  • How to create an application which embeds and runs Python code without local Python installation?

    - by Robert
    Hello fellow software developers. I want to distribute a program which is scriptable by embedding the Python interpreter. What I don't want is that the user has to install Python first. So I'm looking for a solution where I distribute only the following components: my program executable and its libraries the Python library (dll/so) a ZIP-file containing all necessary Python modules and libraries. How can I accomplish this? Do you have a step-by-step recipe for me? The solution should be suitable for both Windows and Linux. Thanks in advance.

  • keep open windows console after a python syntax error

    - by basweber
    File associations on my machine (winxp home) are such that a python script is directly opened with the python interpreter. If I double click on a python script a console window runs and every thing is fine - as long as there is no syntax error in the script. In that case the console window opens up for a moment but it is closed immediately. Too fast to read the error message. Of course their would be the possibility to manually open a console window and to execute the script by typing python myscript.py but I am sure that there is a more convenient (i.e. "double click based") solution.

  • Python+Windows+GStreamer = Impossible (for me)?

    - by james
    Hi :) essentially, my problem is, ater a long time searching, finding only this other question, i decided i was just going to ask my own... i am on windows 7 with python 2.6 and ossbuild GStreamer, but i am trying to get the python binding for it, and struggling. i have got gst-python from http://gstreamer.freedesktop.org/src/gst-python/ but as my eyes and research tell me, it does not work in the setup.py way, and the other question has a link to a site that he says has a binary avaiable, which no longer does, http://www.gstreamer-winbuild.ylatuya.es/doku.php?id=download and even the sdk is gone, and ossbuild dont seem to have anything useful either. so essentially, my question is, can anyone tell me a method, however convoluted, of getting my setup so if i write a script for (py)gst, with an import gst it will work? not the best of explanations... im tired k? xxx :)

  • Gathering mac addresses with Python

    - by William
    Hi, is there a good way to gather the mac addresses of machines on a local network using Python. If it helps I'm trying to execute this python script from the DHCP server for the network. I'm new to Python but would it be a bad idea to look at the DHCP leases file for this info? I'd like to use this inside a Django app eventually. Thanks.

  • Code indentation helper for gedit (python).

    - by aviraldg
    See the little vertical lines? They're damn helpful when writing Python code. Any chance I could get something similar for gedit? I wouldn't mind having to write my own plugin, as long as it's in Python... So: Is there a plugin for this in gedit? If not, would it be possible to write one in Python.

  • What are Class methods in Python for?

    - by Dave Webb
    I'm teaching myself Python and my most recent lesson was that Python is not Java, and so I've just spent a while turning all my Class methods into functions. I now realise that I don't need to use Class methods for what I would done with static methods in Java, but now I'm not sure when I would use them. All the advice I can find about Python Class methods is along the lines of newbies like me should steer clear of them, and the standard documentation is at its most opaque when discussing them. Does anyone have a good example of using a Class method in Python or at least can someone tell me when Class methods can be sensibly used?

  • stting environment variables in powershell by calling python script that prints $env:myVar=myvalue

    - by leeg
    I have some legacy python scripts that manage my shell environment for all the programs and plugins I am running on Linux (bash) and windows (cmd.exe). I want to port this to powershell. How do I set environment variables in powershell by calling python script that prints $env:myVar=myvalue and causes my environment variable to persist in the powershell. In Bash I can use a bash function to call my python script which prints export var=value to stdout and the function will set the environment variables in my shell. This will also work in windows cmd shell by calling a .bat file. I cannot figure out how to do this in powershell. I think it should be something like this: setvar.ps1: function SETVAR {c:\python26\python.exe varconfig.py } varconfig.py: import sys print >> sys.stdout, '$env:myVar=foo'

  • Python Interactive Interpreter always returns "Invalid syntax" on Windows

    - by user559217
    I've encountered an extremely confusing problem. Whatever I type into the Python interpreter returns "Invalid Syntax". See examples below. I've tried fooling around with the code page of the prompt I run the interpreter from, but it doesn't seem to help at all. Furthermore, I haven't been able to find this particular, weird bug elsewhere online. Any assistance anyone could provide would be lovely. I've already tried reinstalling Python, but I didn't have any luck - the problem is also there in both 3.13 and 2.7. Running: Python version 3.1.3, Windows XP SP3. Getting: C:\Program Files\Python31>.\python Python 3.1.3 (r313:86834, Nov 27 2010, 18:30:53) [MSC v.1500 32 bit (Intel)] on win32 Type "help", "copyright", "credits" or "license" for more information. >>> 2+2 File "<stdin>", line 1 2+2 ^ SyntaxError: invalid syntax >>> x = "Oh, fiddlesticks."

  • python object to native c++ pointer

    - by Lodle
    Im toying around with the idea to use python as an embedded scripting language for a project im working on and have got most things working. However i cant seem to be able to convert a python extended object back into a native c++ pointer. So this is my class: class CGEGameModeBase { public: virtual void FunctionCall()=0; virtual const char* StringReturn()=0; }; class CGEPYGameMode : public CGEGameModeBase, public boost::python::wrapper<CGEPYGameMode> { public: virtual void FunctionCall() { if (override f = this->get_override("FunctionCall")) f(); } virtual const char* StringReturn() { if (override f = this->get_override("StringReturn")) return f(); return "FAILED TO CALL"; } }; Boost wrapping: BOOST_PYTHON_MODULE(GEGameMode) { class_<CGEGameModeBase, boost::noncopyable>("CGEGameModeBase", no_init); class_<CGEPYGameMode, bases<CGEGameModeBase> >("CGEPYGameMode", no_init) .def("FunctionCall", &CGEPYGameMode::FunctionCall) .def("StringReturn", &CGEPYGameMode::StringReturn); } and the python code: import GEGameMode def Ident(): return "Alpha" def NewGamePlay(): return "NewAlpha" def NewAlpha(): import GEGameMode import GEUtil class Alpha(GEGameMode.CGEPYGameMode): def __init__(self): print "Made new Alpha!" def FunctionCall(self): GEUtil.Msg("This is function test Alpha!") def StringReturn(self): return "This is return test Alpha!" return Alpha() Now i can call the first to functions fine by doing this: const char* ident = extract< const char* >( GetLocalDict()["Ident"]() ); const char* newgameplay = extract< const char* >( GetLocalDict()["NewGamePlay"]() ); printf("Loading Script: %s\n", ident); CGEPYGameMode* m_pGameMode = extract< CGEPYGameMode* >( GetLocalDict()[newgameplay]() ); However when i try and convert the Alpha class back to its base class (last line above) i get an boost error: TypeError: No registered converter was able to extract a C++ pointer to type class CGEPYGameMode from this Python object of type Alpha I have done alot of searching on the net but cant work out how to convert the Alpha object into its base class pointer. I could leave it as an object but rather have it as a pointer so some non python aware code can use it. Any ideas?
