[Tutor] Online Scripting

[Omer]

Hello.

I started a project with a goal: To have a script "read" an entire message
board, dedicated to various events,
process this information into an iCalendar file,
and finally- base a Google Calendar on the iCal file.

Now,
The script is done and it works great on my desktop.
The problem is, seeing as I plan this a sort of a service for the forum
people,
It can't be based off of my desktop, which is only available 5 ~ 6 days a
week.

So,

Has anyone a clue as to where might I host my script, so's A: the host
"runs" my script periodical (Once every Two hours? If I can configure it to
only run during the day than that's even better), and B: The host lets my
script create an iCal file (a single, <1MB file) and C: lets GCal have
access to this file.

I've looked Google App Engine. It's a huge effort: First remodeling my
script to use the GAE way of opening urls, to use the GAE way of storing
information, and I haven't as yet even looked into how do I store the
prepared iCal file, or how do I schedule the runs of my script. The need to
learn an entire platform, (Although I do plan to learn it someday), is too
large for me now. (Although, if there's no choice that's what I'll do.)

Sorry about this message's length,
Help will be appreciated, thank you for your time.
Omer.

Re: [Tutor] Looking at a String as a Struct?

[Omer]

Class Person:
def __init__(str):
self.Firstname = str[0:4]
self.Surname = str[5:7]
(...)

If your string separates the values of each person using tags rather than
fixed lengthes, build it like:

or:
self.Firstname = str[0:str.find("Last name:")]
self.Surname = str[str.find("Last name:")+len("Last
name:"):str.find("date_of_birth")]

And just create a list of these, adding various get methods for easy
information retrieval.

(Here's for wandering whether my way of doing it counts as Pythonic.)
HTH.
Omer.

Re: [Tutor] Printing Scripts with color/good formatting

I went through a similar process:
I got used to PyWin on XP, then when switching to Vista pywin did not
install with Python.
So I simply downloaded and installed it.

No, I shouldn't think it is. Lots o' folk use this list in archived mode and
the important bit is that each question comes with an answer, regardless of

[Tutor] Class Extend Help

[Omer]

Hey.

I'm trying to do something I think is basic and am failing.

The goal is:
[mimicking the google urlopen syntax]

try:
from google.appengine.api.urlfetch import fetch
except:
from urllib import urlopen as fetch


How do I add this "fetch" the property of content?

I basically want fetch(url.com).content to replace urlopen(url.com).read()

Mind, content is not a method.

Thoughts?

Thx. Omer.

[Tutor] Fwd: Class Extend Help

[Omer]

Hey!

Thx for the help,

@Martin,
At the moment my only need is basic retrievals of source code of basic files
from the internet, so no need for urllib2 or response objects just yet.


Now, copying and pasting line by line into the interactive mode I get this:

>>> from urllib import urlopen
>>> class fetch(urlopen):
... def __init__(self,*args):
... urlopen.__init__(self, *args)
... self.content = self.read()
...

Traceback (most recent call last):
  File "", line 1, in 
TypeError: Error when calling the metaclass bases
function() argument 1 must be code, not str

Anybody, any idea what's up with that?

[Tutor] RE Silliness

[Omer]

I'm sorry, burrowed into the reference until my eyes bled.

What I want is to have a regular expression with an optional ending of
""

(For those interested,
urlMask = r"http://[\w\Q./\?=\R]+";
is ther version w/o the optional  ending.)

I can't seem to make a string optional- only a single character via []s. I
for some reason thuoght it'll be ()s, but no help there- it just returns
only the . Anybody?

Thx,
Omer.

Re: [Tutor] RE Silliness

[Omer]

Bob, I tried your way.

>>> import re
>>> urlMask = r"http://[\w\Q./\?=\R]+()?"
>>> text=u"Not working examplehttp://this.is.a/url?header=nullAnd
another linehttp://and.another.url";
>>> re.findall(urlMask,text)
[u'', u'']

spir, I did understand it. What I'm not understanding is why isn't this
working.

(Whereas,

>>> OldurlMask = r"http://[\w\Q./\?=\R]+";   #Not f-ing working.
>>> re.findall(OldurlMask,text)
['http://this.is.a/url?header=null', 'http://and.another.url']

does work. Which is what had me frowning.
Also,
this ugly url mask is working:

>>> UglyUrlMask = r"(http://[\w\Q./\?=\R]+|http://[\w\Q./\?=\R]+)"
>>> re.findall(UglyUrlMask,text)
['http://this.is.a/url?header=null', 'http://and.another.url']

Anyone?)
