python-2.6

问题 I am having difficulty in formatting some code in Python: My code is here: keys = ['(Lag)=(\d+\.?\d*)','\t','(Autocorrelation Index): (\d+\.?\d*)', '(Autocorrelation Index): (\d+\.?\d*)', '(Semivariance): (\d+\.?\d*)'] import re string1 = ''.join(open("dummy.txt").readlines()) found = [] for key in keys: found.extend(re.findall(key, string1)) for result in found: print '%s = %s' % (result[0],result[1]) raw_input() So far, I am getting this output: Lag = 1 Lag = 2 Lag = 3 Autocorrelation Index

问题 I need to disable nagle algorithm in python2.6. I found out that patching HTTPConnection in httplib.py that way def connect(self): """Connect to the host and port specified in __init__.""" self.sock = socket.create_connection((self.host,self.port), self.timeout) self.sock.setsockopt(socket.IPPROTO_TCP, socket.TCP_NODELAY, True) # added line does the trick. Obviously, I would like to avoid patching system lib if possible. So, the question is: what is right way to do such thing? (I'm pretty new

问题 I am using python 2.6.6 and I need to overload the default python print function. I need to do it because this code may be used on a system where a built-in function has to be used to generate output, otherwise no output is displayed. So, just for example, if you have a python script like this: from __future__ import print_function def NewPrint(Str): with open("somefile.txt","a") as AFile: AFile.write(Str) def OverloadPrint(): global print print = NewPrint OverloadPrint() print("ha") It works

问题 In Python, how can I have one setup (which may contain expensive function calls) for a whole set of unit tests? Example: import unittest class Test1(unittest.TestCase): def setUp(self): print "expensive call" def test1(self): self.assertEqual(1, 1) def test2(self): self.assertEqual(1, 1) if __name__ == "__main__": unittest.main() Will run the expensive call twice: $ python unittest.py expensive call .expensive call . ---------------------------------------------------------------------- Ran 2

问题 I'm trying to make a file like object which is meant to be assigned to sys.stdout/sys.stderr during testing to provide deterministic output. It's not meant to be fast, just reliable. What I have so far almost works, but I need some help getting rid of the last few edge-case errors. Here is my current implementation. try: from cStringIO import StringIO except ImportError: from StringIO import StringIO from os import getpid class MultiProcessFile(object): """ helper for testing multiprocessing

问题 I am not able to install any additional modules on an AIX server I am scripting on. It has Python 2.6.2 installed and basically I am trying to run the below command psql -c "select * from cms_agprm;" -o u350932.txt -d tctmsv80 -U tctmsv80 Now I have done some goggling and found a few different recommendation on how to do this. None with much success. I'm also a little paranoid because I am dealing with processes and want to make sure that i get things right in this script otherwise things

问题 I have Python 2.7 operating correctly on Windows. I installed 2.6 in another folder. However, when I run 2.6 in IDLE or PowerShell , it does not recognize basic commands and cannot import installed libraries. Whenever I launch 2.6, the first thing that comes up is: 'import site' failed; use -v for traceback I can't find anything on this error aside from some mentions with specific libraries. Trying again using -v suggests 2.6 is pulling libraries from 2.7 which is causing some of the errors.

问题 I'm doing something very similar to what this user was doing: trying to load a javascript object declaration into a python dictionary. However, unlike that user, the property names aren't enclosed in quotes. >>> simplejson.loads('{num1: 1383241561141, num2: 1000}') Traceback (most recent call last): File "<stdin>", line 1, in <module> File "/Users/lalalal/site-packages/simplejson/__init__.py", line 385, in loads return _default_decoder.decode(s) File "/Users/lalalal/site-packages/simplejson

问题 I'm busy creating a function in my rigging tool which allows mirroring of joints and replacing the prefix. The mirroring of joints (both behaviours and orientation) is working but I get an error when I search and replace what is in my two text fields. The prefix of joints in the scene is either R_ or L_ and I would like to replace them with this. The error is as follows: NameError: name searchFor is not defined. The odd part here is that I actually create a variable called searchFor and one

问题 I have a problem importing a module: It is under this directory ./dao and the code that calls it is here ./core . Schematically represented as: rnaspace/ __init__.py core/ __init__.py logger.py dao/ __init__.py storage_configuration_reader.py This is the error message: Traceback (most recent call last): File "logger.py", line 21, in <module> from rnaspace.dao.storage_configuration_reader import storage_configuration_reader ImportError: No module named rnaspace.dao.storage_configuration_reader
