I write a program :
from PyQt4.QtCore import *
from PyQt4.QtGui import *
def main():
app = QApplication([])
button = QPushButton("hello?")
button.show()
app.exec_()
if __name__=="__main__":
main()
the file name is t.py,
when I run:
pylint t.py
in ubuntu9.10, pyqt4,
I got this:
pylint t.py

I only got a error message, why?
Looks like a bug in astng. They try to read the name of a function which does not publish it (native extension func). I'd report a bug to both astng and pyqt projects. The first one would be that they should handle a no-name situation better. The second one would be that every sane extension should publish at least the function names.
I would check if you're using the very latest astng, pylint, etc.

try this.

if you are using Windows you need use programs like zadig or LibusbK and install filters.

from Lib.DBVersionTools import DBVersionNormalizer, DBVersionPolisher
ImportError: cannot import name DBVersionPolisher
The module is on the path, and is within a folder with an __init__.py file. Sphinx is clearly able to import the first class, but not the second. Tests involving both classes work fine. I have deleted all of the old .pyc files, but that failed to resolve the issue. If I remove the second class from the import statement and comment out references to it, then the docs work without a problem.
Any ideas on how to fix this issue, or failing that hide the import statements from sphinx (but not other scripts, like my tests)?
Additional code:
All import statements:
import Error
import logging
import re
import Lib.globals as Globals
from flask import Blueprint, jsonify, request, current_app, make_response
from functools import update_wrapper
from datetime import timedelta
from Lib.VerifyCookie import verify, req_to_dict
from Lib.MSSQLTools import MSSQLTools
from Lib.DBVersionTools import DBVersionNormalizer, DBVersionPolisher
Sphinx extensions and path modifications:
sys.path.append('E:\\workspace_zach\\API') # Root directory for the project
extensions = [
'sphinx.ext.autodoc',
'sphinxcontrib.httpdomain',
'sphinxcontrib.autohttp.flask',
'sphinx.ext.autodoc',
'sphinx.ext.viewcode',
]
A previous version of the file, without the modifications being imported, existed on another path of the computer I was developing on, and had been added to the pythonpath.
sys.path.remove('E:\\workspace\\API') was sufficient to remove the other path and fix the problem.
Does anyone have any experience using Python with AutoCAD? I'm just trying, as a test to see if I can open a new instance of AutoCAD via Python and though that PyAutocad worked well (feel free to offer other suggestions, if you have any).
Anyway based on the doc (https://pypi.python.org/pypi/pyautocad/#downloads) - it says these lines of code should do it, but nothing's happened as of yet.
from pyautocad import Autocad, APoint
acad = Autocad()
acad.prompt("Hello, Autocad from Python\n")
Just these lines of code should generate info on the commandline but instead results in about 50 lines worth of traceback (which I can post as well if anyone's interested) - any ideas?
Traceback (most recent call last):

After adding the VBA Module, the traceback now reads:

Have you considered IronPython?
http://through-the-interface.typepad.com/through_the_interface/2009/03/using-ironpython-with-autocad.html
Here's a quick example of how it could be leveraged:
import clr
import System
from System import Type, Activator
acApp = Activator.CreateInstance(Type.GetTypeFromProgID("AutoCAD.Application"))
acApp.Visible = 1
acApp.ActiveDocument.SendCommand("(Princ \"Hello World from Python!\")(Princ)\n")
Obviously the ProgId will correspond to whichever version of AutoCAD was opened last.
I am trying to run Pyramid with Jinja2 using new Python 2.7 runtime in threadsafe mode and GAE 1.6.0 pre-release SDK. I've made modifications to my app as outlined here, i.e. I've set runtime: python27, threadsafe: true in app.yaml and got rid of main() function. When I generate response by myself it works fine, but when I try to bring jinja2 into the equation, I get the following exception:

ImportError: Cannot re-init internal module __main__
I'd be happy if anybody could shed some light on what pyramid is trying to do under the hood. Judging by the latter stack trace it seems it's trying to resolve an asset, but why is it trying to reload __main__? I'm not even sure my problem is caused by pyramid or GAE.
Thanks for any insight on this issue.
I'm not familiar with pyramid, but the problem really does seem to be with this line:
config.include('pyramid_jinja2')
Whatever that config thing is, it seems to be doing some dynamic import magic.
Don't do that.
The app engine environment doesn't handle imports the way you would in normal python. Step through that line with a debugger and you'll wind up in the replacement version of the import system, which you'll soon see, only implements a small part of what real python does.
If possible, just use a normal import statement... Otherwise, you're going to have to dig into config.include and get it to play nice with the restricted importing features on GAE.
I managed to make it work using Pyramid 1.3's AssetResolver. First attempt is here. Just not sure what the lifetime/scope of the resolver should be in this case, I will figure it out later.
In pyramid_jinja2/__init__.py add the following code before _get_or_build_default_environment()
class VirtualModule(object):
def __init__(self,name):
import sys
sys.modules[name]=self
def __getattr__(self,name):
return globals()[name]
VirtualModule("__main__")
