  • Why can't I install psycopg2? (Python 2.6.4, PostgreSQL 8.4, OS X 10.6)

    - by cojadate
    After running python setup.py install I get the following: Warning: Unable to find 'pg_config' filebuilding 'psycopg2._psycopg' extension gcc-4.0 -arch ppc -arch i386 -fno-strict-aliasing -fno-common -dynamic -DNDEBUG -g -O3 - DPSYCOPG_DEFAULT_PYDATETIME=1 -DPSYCOPG_VERSION="2.2.1 (dt dec ext pq3)" -DPSYCOPG_EXTENSIONS=1 -DPSYCOPG_NEW_BOOLEAN=1 -DHAVE_PQFREEMEM=1 -DHAVE_PQPROTOCOL3=1 -I/Library/Frameworks/Python.framework/Versions/2.6/include/python2.6 -I. -c psycopg/psycopgmodule.c -o build/temp.macosx-10.3-fat-2.6/psycopg/psycopgmodule.o unable to execute gcc-4.0: No such file or directory error: command 'gcc-4.0' failed with exit status 1 There's probably something screamingly obvious there to anyone who knows the first thing about back-end web programming, but unfortunately it's all gobbledegook to me. The psycopg2 documentation was not helpful.

  • Python: Is there a way to get HTML that was dynamically created by Javascript?

    - by Joschua
    As far as I can tell, this is the case for LyricWikia. The lyrics (example) can be accessed from the browser, but can't be found in the source code (can be opened with CTRL + U in most browsers) or reading the contents of the site with Python: from urllib.request import urlopen URL = 'http://lyrics.wikia.com/Billy_Joel:Piano_Man' r = urlopen(URL).read().decode('utf-8') And the test: >>> 'Now John at the bar is a friend of mine' in r False >>> 'John' in r False But when you select and look at the source code of the box in which the lyrics are displayed, you can see that there is: <div class="lyricbox">[...]</div> Is there a way to get the contents of that div-element with Python?

  • What is the advantage of using static methods in Python?

    - by Curious2learn
    I ran into unbound method error in python with the code class Sample(object): '''This class defines various methods related to the sample''' def drawSample(samplesize,List): sample=random.sample(List,samplesize) return sample Choices=range(100) print Sample.drawSample(5,Choices) After reading many helpful posts here, I figured how I could add @staticmethod above to get the code working. I am python newbie. Can someone please explain why one would want to define static methods? Or, why are not all methods defined as static methods. Thanks in advance.

  • [Python] How do I read binary pickle data first, then unpickle it?

    - by conradlee
    I'm unpickling a NetworkX object that's about 1GB in size on disk. Although I saved it in the binary format (using protocol 2), it is taking a very long time to unpickle this file---at least half an hour. The system I'm running on has plenty of system memory (128 GB), so that's not the bottleneck. I've read here that pickling can be sped up by first reading the entire file into memory, and then unpickling it (that particular thread refers to python 3.0, which I'm not using, but the point should still be true in python 2.6). How do I first read the binary file, and then unpickle it? I have tried: import cPickle as pickle f = open("big_networkx_graph.pickle","rb") bin_data = f.read() graph_data = pickle.load(bin_data) But this returns: TypeError: argument must have 'read' and 'readline' attributes Any ideas?

  • How do I get python to load .NET .dlls referenced by mixed mode .dlls?

    - by Michael Kelley
    I have a python .pyd that is a mixed mode C++ DLL. The DLL loads fine and loads unmanaged C++ dlls without a problem, but when it tries to load the .NET dlls referenced by the managed C++ dlls it fails with this error message: Unhandled Exception: System.IO.FileNotFoundException: Could not load file or assembly '...' Copying these .NET dlls to the directory that pythod_d.exe is contained in allows the .NET libraries to load successfully, but this is not a good long term solution. Is there an environment variable I have to set or some command line option to python_d.exe that will solve my problem? Note that using IronPython or Python .NET is NOT acceptable.

  • How to install python package without copy everything into lib/site-packages?

    - by Victor Lin
    I want to develop a common python package, I got other packages depends on it. For example: packageA/ packageB/ packageC/ commonPackage/ packageA, packageB and packageC can all be executed directly, but they are all depend on commonPackage. I want to install the commonPackage into lib/site-packages, but I don't want it copys the source code. Instead, I want it creates a commonPackage.pth in lib/site-packages with the path of where the commonPackage at. So that when I modify commonPackage or update it from SVN, I don't need to install it again. Here comes the problem, how can I write the setup.py or use the options of python setup.py install so that it would do what I want?

  • How do you enable block folding for Python comments in TextMate?

    - by Dave Gallagher
    In TextMate 1.5.10 r1623, you get little arrows that allow you to fold method blocks: Unfortunately, if you have a multi-lined Python comment, it doesn't recognize it, so you can't fold it: def foo(): """ How do I fold these comments? """ print "bar" TextMate has this on their site on how to customize folding: http://manual.macromates.com/en/navigation_overview#customizing_foldings ...but I'm not skilled in regex enough to do anything about it. TextMate uses the Oniguruma regex API, and I'm using the default Python.tmbundle updated to the newest version via GetBundles. Does anyone have an idea of how to do this? Thanks in advance for your help! :)

  • How can I create a simple message box in Python?

    - by Carson Myers
    I'm looking for the same effect as alert() in JavaScript. I wrote a simple web-based interpreter this afternoon using Twisted.web. You basically submit a block of Python code through a form, and the client comes and grabs it and executes it. I want to be able to make a simple popup message, without having to re-write a whole bunch of boilerplate wxPython or TkInter code every time (since the code gets submitted through a form and then disappears). I've tried tkMessageBox: import tkMessageBox tkMessageBox.showinfo(title="Greetings", message="Hello World!") but this opens another window in the background with a tk icon. I don't want this. I was looking for some simple wxPython code but it always required setting up a class and entering an app loop etc. Is there no simple, catch-free way of making a message box in Python?

  • Why bother to limit the types imported from a python package?

    - by Fast Fish
    When using many IDEs that support autocompletion with Python, things like this will show warnings, which I find annoying: from eventlet.green.httplib import BadStatusLine When switching to: rom eventlet.green.httplib * The warnings go away. What's the benefit to limiting imports to a specific set of types you'll use? Is the parsing faster? Reduces collisions? What other point is there? It seems the state of python IDEs and the nature of the typing system makes it hard for many IDEs to fully get right when a type import works and when it doesn't.

  • How can I detect if a file is binary (non-text) in python?

    - by grieve
    How can I tell if a file is binary (non-text) in python? I am searching through a large set of files in python, and keep getting matches in binary files. This makes the output look incredibly messy. I know I could use grep -I, but I am doing more with the data than what grep allows for. In the past I would have just searched for characters greater than 0x7f, but utf8 and the like make that impossible on modern systems. Ideally the solution would be fast, but any solution will do.

  • Should I bundle C libraries with my Python application?

    - by oceanhug
    If I have a Python package that depends on some C libraries (like say the Gnu Scientific Library (GSL) for numerical computations), is it a good idea to bundle the library with my code? I'd like to make my package as easy to install as possible for users and I don't want them to have to download C libraries by hand and supply include-paths. Also I could always ensure that the version of the library that I ship is compatible with my code. However, is it possible that there are clashes if the user has the library installed already, or ar there any other reasons why I shouldn't do this? I know that I can make it easier for users by just providing a binary distribution, but I'd like to avoid having to maintain binary distributions for all possible OSs. So, I'd like to stick to a source distribution, but for the user (who proudly owns a C compiler) installation should be as easy as python setup.py install.

    Can you please convert this code from C# to Python to be run on IronPython? I don’t have any experience with Python. using System; using Baz; namespace ConsoleApplication { class Program { static void Main() { Portal foo = new Portal("Foo"); Agent bar = new Agent("Bar"); foo.Connect("127.0.0.1", 1234); foo.Add(bar); bar.Ready += new Agent.ReadyHandler(bar_Ready); } static void bar_Ready(object sender, string msg) { Console.WriteLine(msg.body); } } }

  • How do you validate a URL with a regular expression in Python?

    - by Zachary Spencer
    I'm building a Google App Engine app, and I have a class to represent an RSS Feed. I have a method called setUrl which is part of the feed class. It accepts a url as an input. I'm trying to use the re python module to validate off of the RFC 3986 Reg-ex (http://www.ietf.org/rfc/rfc3986.txt) Below is a snipped which should work, right? I'm incredibly new to Python and have been beating my head against this for the past 3 days. p = re.compile('^(([^:/?#]+):)?(//([^/?#]*))?([^?#]*)(\?([^#]*))?(#(.*))?') m = p.match(url) if m: self.url = url return url

  • How important is it to use short names for Python packages and modules?

    - by Dan
    PEP 8 says that Python package and module names should be short, since some file systems will truncate long names. And I'm trying to follow Python conventions in a new project. But I really like long, descriptive names. So I'm wondering, how short do names need to be to comply with PEP 8. And does anyone really worry about this anymore? I'm tempted to ignore this recommendation, and use longer names, thinking this isn't all that relevant anymore. Does anyone think this recommendation is still worth following? If yes, why? And how short is short enough?

  • How can I tell Phusion Passenger which python to use?

    - by Mike
    I'm using Phusion Passenger with a ruby app and I'd also like to set it up to work with an django appengine app I'm working on. Googling for "passenger_wsgi.py" I was able to get the following very simple non-django app working on passenger: passenger_wsgi.py: def application(environ, start_response): response_headers = [('Content-type','text/plain')] start_response('200 OK', response_headers) return ['Hello World!\n'] However, if I add the line import django.core.handlers.wsgi into the mix, I get 'An error occurred importing your passenger_wsgi.py'. By printing out the sys.path I've discovered that at least part of the reason is because Passenger is using the wrong python installation on my machine. How can I configure Passenger (on apache) to use /opt/local/bin/python2.5 instead of the system default python?

  • Can this loop be sped up in pure Python?

    - by Noctis Skytower
    I was trying out an experiment with Python, trying to find out how many times it could add one to an integer in one minute's time. Assuming two computers are the same except for the speed of the CPUs, this should give an estimate of how fast some CPU operations may take for the computer in question. The code below is an example of a test designed to fulfill the requirements given above. This version is about 20% faster than the first attempt and 150% faster than the third attempt. Can anyone make any suggestions as to how to get the most additions in a minute's time span? Higher numbers are desireable. EDIT: This experiment is being written in Python 3.1 and is 15% faster than the fourth speed-up attempt. def start(seconds): import time, _thread def stop(seconds, signal): time.sleep(seconds) signal.pop() total, signal = 0, [None] _thread.start_new_thread(stop, (seconds, signal)) while signal: total += 1 return total if __name__ == '__main__': print('Testing the CPU speed ...') print('Relative speed:', start(60))

  • Python: why does str() on some text from a UTF-8 file give a UnicodeDecodeError?

    - by AP257
    I'm processing a UTF-8 file in Python, and have used simplejson to load it into a dictionary. However, I'm getting a UnicodeDecodeError when I try to turn one of the dictionary values into a string: f = open('my_json.json', 'r') master_dictionary = json.load(f) #some json wrangling, then it fails on this line... mysql_string += " ('" + str(v_dict['code']) Traceback (most recent call last): File "my_file.py", line 25, in <module> str(v_dict['code']) + "'), " UnicodeEncodeError: 'ascii' codec can't encode character u'\xf4' in position 35: ordinal not in range(128) Why is Python even using ASCII? I thought it used UTF-8 by default, and this is a UTF-8 file. What is the problem?

  • How can I reshape and aggregate list of tuples in Python?

    - by radek
    I'm a newb to Python so apologies in advance if my question looks trivial. From a psycopg2 query i have a result in the form of a list of tuples looking like: [(1, 0), (1, 0), (1, 1), (2, 1), (2, 2), (2, 2), (2, 2)] Each tuple represents id of a location where event happened and hour of the day when event took place. I'd like to reshape and aggregate this list with subtotals for each hour in each location, to a form where it looks like: [(1, 0, 2), (1, 1, 1), (1, 2, 0), (2, 0, 0), (2, 1, 1), (2, 3, 3)] Where each touple will now tell me that, for example: in location 1, at hour 0 there were 2 events; in location 1, at hour 1 there was 1 event; and so on... If there were 0 events at certain hour, I still would like to see it, as for example 0 events at 0 hours in location 2: (2, 0, 0) How could I implement it in Python?
