Re: [Tutor] Python 3.2 Install Not Responding To Python Command!!
I know this was a while ago but you can add the ppa by going to the terminal and typing: sudo add-apt-repository ppa:irie/python3.2 then sudo apt-get update and sudo apt-get install python3.2 Rohan On Sun, Apr 10, 2011 at 1:33 PM, Walter Prins wrote: > > > On 9 April 2011 19:45, Nevins Duret wrote: > >> I can't thank you enough for your help.

First try to learn how to read a web page. You are right to look into urlib and urlib2. Its only a handful of lines of code to open a web page and retrieve it to your system. Once you do that there is a package called beautiful soup that is a good tool to read through the tags in the page Let us know how you are doing. -- Joel Goldstick ___ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: http://mail.python.org/mailman/listinfo/tutor

Re: [Tutor] Pictures
Observing the page source i think :
page=urllib.urlopen('http://finance.blog.lemonde.fr').read()
x=re.findall(r"http://s2.lemde.fr/image/2011/02/16/87x0/1480844_7_87fe_bandeau-lycee-electrique.jpg
"
x.extend(y)
x=list(set(x))
for img in x:
image=img.split('.')[-1]
if image=='jpg':
print img

[Tutor] distutils site.cfg variable expansion
I'm learning my way around package building using setuptools, and would like to have scripts for a system administration package installed under $(prefix)/sbin instead of under the default $(prefix)/bin directory without requiring the installer to use the manual 'python setup.py install --install-scripts=...'. I would like to have something in the setup.cfg file like this which would be handled by the normal ConfigParser expansion. Either I have the syntax wrong, or the setuptools/distutils configuration parsing is different. [global] prefix=/path/to/prefix [install] install-scripts=%(prefix)s/sbin Better yet would be for the prefix to be available from the command line or taken from sys.prefix if not specified. Is there a way to do this other than fiddling the site.cfg file? Bill -- INTERNET: b...@celestial.com Bill Campbell; Celestial Software LLC URL: http://www.celestial.com/ PO Box 820; 6641 E.

[Tutor] Calling a python script using subprocess
I am trying to execute a python script using the subprocess module. I am feeding parameters into the script, which reads them using argparse and returns a list. The script simply returns a list when called. When I execute my script from my prompt, I get the following: H:\pythonscripts>installModule.pyc --mods mod1 mod2 mod3 ['mod1', 'mod2', 'mod3'] # This is the result I would like When I call the script from within another script using subprocess I get an error: p = subprocess.Popen(r'installModule.py --mods mod1 mod2 mod3', executable = sys.executable, stdout = subprocess.PIPE, stderr = subprocess.STDOUT) 'Unknown option: --\r\n' 'usage: installModule.py [option] ... [-c cmd | -m mod | file | -] [arg] ...\r\n' Is the subprocess module the best thing for me to use? Is there a better way to call this script?___ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: http://mail.python.org/mailman/listinfo/tutor
