Reminder: 9th London Python Code Dojo next week
by Nicholas Tollervey April 29, 2010

April 29, 2010

Folks, A quick reminder that the next London Python Code Dojo is a week away. It's on 6th May, starts at 6:30pm (coding at 7:30) and will be at the offices of Fry-IT (details at the end). You can sign up here (just so we know how much pizza to order): http://ldnpydojo.eventwax.com/9th-london-python-code-dojo We hope to get close to finishing the text-adventure game we've been writing by adding behaviour to objects and puzzles. Peter will start the evening with a quick recap on the Bayesian parser we "blessed" at the end of the last dojo and we'll work in teams as before. As always, free pizza and beer will be provided by Fry-IT (thanks!) and there is also a copy of "Natural Language Processing with Python" to win (thanks to O'Reilly). Look forward to seeing you there! Nicholas. Venue: Fry-IT Limited 503 Enterprise House 1/2 Hatfields London SE1 9PG Telephone: 0207 0968800 Nearest Tubes: Waterloo Southwark

April 29, 2010

Hi, I have a query. I have two modules viz. MnSem5Main.py and MnCEMMain.py in different folders. I have created the below instances in MnSem5Main.py: 'app' , 'frame' Please note that 'app' is created using wx.App and 'frame' using wx.Frame builtin classes. I want to access these in MnCEMMain.py. How to access these instances?

Next CamPUG meeting, Tue 4th May
by Tony Ibbs April 27, 2010

April 27, 2010

As it says on our Google group: The next meeting will be 7.30pm, Tuesday 4th May, at RealVNC (http://tinyurl.com/realvncoffices). Since this is rather short notice, it's probably sensible to do a lightning talks meeting, so if you have something that can be explained in five minutes or so, please do so. As normal, volunteers beforehand to myself or the list, or just turn up and talk. If someone did get to last weekend's BarCamb meeting (I know Robin was hoping to go), that would be worth telling us about. Subsequent meetings are expected to be: * Tue 1st June, which should be another Dojo meeting (and I shall be away) * Tue 6th July, another talks meeting (I shan't repeat the EuroPython advert here) Tibs

Announcing the 9th London Python Code Dojo
by Nicholas Tollervey April 16, 2010

April 16, 2010

Folks, When..? 6th May 18:30 – 21:30 (ish). Where..? The usual place: Fry-IT Ltd, 503 Enterprise House, 1/2 Hatfields, London SE1 9PG Sign-up here: http://ldnpydojo.eventwax.com/9th-london-python-code-dojo Peter B. will give a quick talk at the start of this dojo so everyone can catch up with where we’re at in terms of the bayesian parser that was "blessed" at the end of the last dojo. Dave K. suggested that we add behaviour to objects and the ability to create/define puzzles. If we manage to pull that off we have a more-or-less finished adventure game. :-) Photos from all the dojos so far can be found here: http://divvyshot.com/event/IsJtx/ (a photo sharing site built w/Python) Free pizza and beer will be provided. (Thanks Fry-IT) Participants get the chance to win a cool book: "Natural Language Processing with Python". (Thanks O'Reilly) Remember to bring a laptop with Python and GIT installed (actually, shouldn't we be using Mercurial..?) Looking forward to it, Nicholas.

easy_install pip won't work, am concerned Ministry of Packaging may chase after me.
by Mike MacCana April 1, 2010

April 1, 2010

Hey UK Pythonistas, In accordance with the new directives issed at http://s3.pixane.com/python_comrades.png, I've installed virtualenv and virtualenv_wrapper, made, and activated a project like so: # mkvirtualenv imeveryone # workon imeveryone However using the easy_install inside the virtualenv to install pip doesn't seem to be working. But easy_install inside the virtualenv does successfully install other packages (eg, I tried installing ipython and it was fine). Am I doing something wrong? I'm not really experienced with the various Python packaging tools. [Note the system is Ubuntu 10.04 beta, but I don't think that's the cause of the prob] Full output is below. Thanks for your help, much appreciated, Mike (imeveryone)root@mike-desktop:~# easy_install pip /root/.virtualenvs/imeveryone/bin/easy_install:5: UserWarning: Module pkg_resources was already imported from /root/.virtualenvs/imeveryone/lib/python2.6/site-packages/setuptools-0.6c9-py2.6.egg/pkg_resources.py, but /usr/lib/python2.6/dist-packages is being added to sys.path from pkg_resources import load_entry_point /root/.virtualenvs/imeveryone/bin/easy_install:5: UserWarning: Module site was already imported from /root/.virtualenvs/imeveryone/lib/python2.6/site.pyc, but /usr/lib/python2.6/dist-packages is being added to sys.path from pkg_resources import load_entry_point Searching for pip Reading http://pypi.python.org/simple/pip/ Reading http://pip.openplans.org Best match: pip 0.6.3 Downloading http://pypi.python.org/packages/source/p/pip/pip-0.6.3.tar.gz#md5=0602fa917… Processing pip-0.6.3.tar.gz Running pip-0.6.3/setup.py -q bdist_egg --dist-dir /tmp/easy_install-bgHiZO/pip-0.6.3/egg-dist-tmp-9OS3pv Traceback (most recent call last): File "/root/.virtualenvs/imeveryone/bin/easy_install", line 8, in <module> load_entry_point('setuptools==0.6c9', 'console_scripts', 'easy_install')() File "/root/.virtualenvs/imeveryone/lib/python2.6/site-packages/setuptools-0.6c9-py2.6.egg/setuptools/command/easy_install.py", line 1671, in main File "/root/.virtualenvs/imeveryone/lib/python2.6/site-packages/setuptools-0.6c9-py2.6.egg/setuptools/command/easy_install.py", line 1659, in with_ei_usage File "/root/.virtualenvs/imeveryone/lib/python2.6/site-packages/setuptools-0.6c9-py2.6.egg/setuptools/command/easy_install.py", line 1675, in <lambda> File "/usr/lib/python2.6/distutils/core.py", line 152, in setup dist.run_commands() File "/usr/lib/python2.6/distutils/dist.py", line 975, in run_commands self.run_command(cmd) File "/usr/lib/python2.6/distutils/dist.py", line 995, in run_command cmd_obj.run() File "/root/.virtualenvs/imeveryone/lib/python2.6/site-packages/setuptools-0.6c9-py2.6.egg/setuptools/command/easy_install.py", line 211, in run File "/root/.virtualenvs/imeveryone/lib/python2.6/site-packages/setuptools-0.6c9-py2.6.egg/setuptools/command/easy_install.py", line 446, in easy_install File "/root/.virtualenvs/imeveryone/lib/python2.6/site-packages/setuptools-0.6c9-py2.6.egg/setuptools/command/easy_install.py", line 476, in install_item File "/root/.virtualenvs/imeveryone/lib/python2.6/site-packages/setuptools-0.6c9-py2.6.egg/setuptools/command/easy_install.py", line 655, in install_eggs File "/root/.virtualenvs/imeveryone/lib/python2.6/site-packages/setuptools-0.6c9-py2.6.egg/setuptools/command/easy_install.py", line 930, in build_and_install File "/root/.virtualenvs/imeveryone/lib/python2.6/site-packages/setuptools-0.6c9-py2.6.egg/setuptools/command/easy_install.py", line 919, in run_setup File "/root/.virtualenvs/imeveryone/lib/python2.6/site-packages/setuptools-0.6c9-py2.6.egg/setuptools/sandbox.py", line 27, in run_setup File "/root/.virtualenvs/imeveryone/lib/python2.6/site-packages/setuptools-0.6c9-py2.6.egg/setuptools/sandbox.py", line 63, in run File "/root/.virtualenvs/imeveryone/lib/python2.6/site-packages/setuptools-0.6c9-py2.6.egg/setuptools/sandbox.py", line 29, in <lambda> File "setup.py", line 48, in <module> File "/usr/lib/python2.6/distutils/core.py", line 113, in setup _setup_distribution = dist = klass(attrs) File "/root/.virtualenvs/imeveryone/lib/python2.6/site-packages/setuptools-0.6c9-py2.6.egg/setuptools/dist.py", line 223, in __init__ File "/usr/lib/python2.6/distutils/dist.py", line 270, in __init__ self.finalize_options() File "/root/.virtualenvs/imeveryone/lib/python2.6/site-packages/setuptools-0.6c9-py2.6.egg/setuptools/dist.py", line 256, in finalize_options File "/root/.virtualenvs/imeveryone/lib/python2.6/site-packages/setuptools-0.6c9-py2.6.egg/pkg_resources.py", line 1918, in load while parts and parts[-1]=='00000000': ImportError: <module 'setuptools.dist' from '/root/.virtualenvs/imeveryone/lib/python2.6/site-packages/setuptools-0.6c9-py2.6.egg/setuptools/dist.py'> has no 'check_packages' attribute

I might have preferred the gentler 'has been superseded'. :-) So you're recommending installing pip manually, by downloading from PyPI, unzipping and running 'python setup.py install', followed by 'pip install virtualenv virtualenvwrapper'. I know that's not much bother, but in case it enhances my understanding, are there specific reasons why 'easy_install pip' is harmful in this context? By definition this install isn't into a virtualenv. Thanks, Jonathan Jonathan Hartley Made of meat. http://tartley.com tartley(a)tartley.com +44 7737 062 225 twitter/skype: tartley
