Does he?  Are you aware of how he treated Hooke?

He was a great technician, but as a person, you would
not have had him marry your sister.

I think you mean SimpleHTTPRequestHandler.  Note that actually reads
the url path and looks in the file system to get the file of that
name, which isn't what the OP wanted.

The OP might also try the junkbuster proxy (google for it) which I
think was renamed a while back.

For the sake of on-topicness, there is this:



#!/usr/bin/env python

'''$Id$

from BaseHTTPServer import HTTPServer
from SimpleHTTPServer import SimpleRequestHandler

handler = HTTPServer (('', 8000), SimpleRequestHandler)

I don't know if this qualifies as "lightweight", but my current best 
strategy is to block ads using a Squid proxy. My /etc/squid/squid.conf has:

acl ads dstdom_regex -i "/etc/squid/squid.adservers"
http_access deny ads
deny_info javascript:void(0) ads

/etc/squid/squid.adservers came from this site:
http://pgl.yoyo.org/adservers/

Ads completely disappear with no visible errors or unnecessary HTTP 
requests. (Sorry, no Python needed for this one.)

##  I was looking in my database of movie grosses I regulary copy
##  from the Internet Movie Database and noticed I was _only_ 120
##  weeks behind in my updates.
##
##  Ouch.
##
##  Copying a web page, pasting into a text file, running a perl
##  script to convert it into a csv file and manually importing it
##  into Access isn't so bad when you only have a couple to do at
##  a time. Still, it's a labor intensive process and 120 isn't
##  anything to look forwards to.
##
##  But I abandoned perl years ago when I took up Python, so I
##  can use Python to completely automate the process now.
##
##  Just have to figure out how.
##
##  There's 3 main tasks: capture the web page, parse the web page
##  to extract the data and insert the data into the database.
##
##  But I only know how to do the last step, using the odnc tools
##  from win32,

import dbi
import odbc
import re

##  so I snoop around comp.lang.python to pick up some
##  hints and keywords on how to do the other two tasks.
##
##  Documentation on urllib2 was a bit vague, but got the web page
##  after only a ouple mis-steps.

import urllib2

##  Unfortunately, HTMLParser remained beyond my grasp (is it
##  my imagination or is the quality of the examples in the
##  doumentation inversely proportional to the subject
##  difficulty?)
##
##  Luckily, my bag of hints had a reference to Beautiful Soup,
##  whose web site proclaims:
##  Beautiful Soup is a Python HTML/XML parser
##  designed for quick turnaround projects like
##  screen-scraping.
##  Looks like just what I need, maybe I can figure it out after all.

from BeautifulSoup import BeautifulSoup

target_dates = [['11','24','2006','November']]

con = odbc.odbc("IMDB")  # connect to MS-Access database
cursor = con.cursor()

for d in target_dates:
  #
  # build url (with CGI parameters) from list of dates needing
updating
  #
  the_year = d[2]
  the_date = '/'.join([d[0],d[1],d[2]])
  print '%10s scraping IMDB:'  % (the_date),
  the_url = ''.join([r'http://www.imdb.com/BusinessThisDay?
day=',d[1],'&month=',d[3]])
  req = urllib2.Request(url=the_url)
  f = urllib2.urlopen(req)
  www = f.read()
  #
  # ok, page captured. now make a BeatifulSoup object from it
  #
  soup = BeautifulSoup(www)
  #
  # that was easy, much more so than HTMLParser
  #
  # now, _all_ I have to do is figure out how to parse it
  #
  # ouch again. this is a lot harder than it looks in the
  # documentation. I need to get the data from cells of a
  # table nested inside another table and that's hard to
  # extrapolate from the examples showing how to find all
  # the comments on a web page.
  #
  # but this looks promising. if I grab all the table rows
  # (tr tags), each complete nested table is inside a cell
  # of the outer table (whose table tags are lost, but aren't
  # needed and whose absence makes extracting the nested
  # tables easier (when you do it the stupid way, but hey,
  # it works, so I'm sticking with it))
  #
  tr = soup.tr  # table rows
  tr.extract()
  #
  # now, I only want the third nested table. how do I get it?
  # can't seem to get past the first one, should I be using
  # NextSibling or something? 
  #
  # but wait...I don't need the first two tables, so I can
  # simply extract and discard them. and since .extract()
  # CUTS the tables, after two extractions the table I want
  # IS the first one.
  #
  the_table = tr.find('table')  # discard
  the_table.extract()
  the_table = tr.find('table')  # discard
  the_table.extract()
  the_table = tr.find('table')  # weekly gross
  the_table.extract()
  #
  # of course, the data doesn't start in the first row,
  # there's formatting, header rows, etc. looks like it starts
  # in tr number [3]
  #
  ##  >>> the_table.contents[3].td
  ##  How the Grinch Stole Christmas
(2000) 
  #
  # and since tags always imply the first one, the above
  # is equivalent to
  #
  ##  >>> the_table.contents[3].contents[0]
  ##  How the Grinch Stole Christmas
(2000) 
  #
  # and since the title is the first of three cells, the
  # reporting year is
  #
  ##  >>> the_table.contents[3].contents[1]
  ##   2001 
  #
  # finally, the 3rd cell must contain the gross
  #
  ##  >>> the_table.contents[3].contents[2]
  ##   259,674,120
  #
  # but the contents of the first two cells are anchor tags.
  # to get the actual title string, I need the contents of the
  # contents. but that's not exactly what I want either,
  # I don't want a list, I need a string. and the string isn't
  # always in the same place in the list
  #
  # summarizing, what I need is
  #
  ##  print the_table.contents[3].contents[0].contents[0].contents,
  ##  print the_table.contents[3].contents[1].contents[1].contents,
  ##  print the_table.contents[3].contents[2].contents
  #
  # and that almost works, just a couple more tweaks and I can
  # shove it into the database

Running this in Python should create a server running on localhost
port 80 that only serves blank pages:

import SimpleHTTPServer
import SocketServer

class MyHandler(SimpleHTTPServer.SimpleHTTPRequestHandler):
  def do_GET(self):
print >> self.wfile, ""

server = SocketServer.TCPServer(("", 80), MyHandler)
server.serve_forever()

Thanks, tux looks good, the only problem is that one needs to
recompile the kernel which I really don't want to do (so yes, I'm on
linux). Publicfile seems to "know" already too much.

The reason I need this is that my current best strategy to avoid ads
in web pages is putting all ad server names into /etc/hosts and stick
my local ip number next to them (127.0.0.1) so every ad request goes
to my machine. I run apache which has an empty page for 404 errors so
I'll just see that blank page for every ad. Now I guess apache is a
pretty heavy weight guy so I'm looking for a lightweight alternative.
Lighttpd, nginx and company are all too complex and "know" too much. I
even considered just putting netcat into an infinite loop but I'm
afraid if there is a security hole in netcat I might be screwed.

Maybe now that I outlined a little more why I need this others can
come up with more suggestions.

Tkinter container frames

[Ron Provost]

I've been trying to figure out how to use the container option in a frame 
widget in conjunction with the use option with a Toplevel widget.  Which 
according to the documentation I've read sounds like it will give me a Windows 
MDI like application with free-floating child windows within the container 
widget.  Has anyone successfully used this feature?  Here's the code I've been 
playing with.

Thanks for any help.



import Tkinter as Tk


tkRoot = Tk.Tk( )
f = Tk.Frame( tkRoot, container=True )
f.pack( )

t1 = Tk.Toplevel( use=f )
b1  = Tk.Button( t1, text="Pres me" )
b1.pack( )

t2 = Tk.Toplevel( use=f )
b2  = Tk.Button( t2, text="No pres me!" )
b2.pack( )

[OT] minimalist web server

[Daniel Fetchinson]

Hi list,

This is way off topic but maybe somebody knowledgeable can help.

I'm looking for the most minimalist web server ever that does nothing
else than return a fixed static page for every request. Regardless of
what the request is, it just needs to be an HTTP request to port 80,
the web server should return always the same html document. What would
be the best choice for this? The goal is of course to minimize system
resources in terms of memory, cpu, etc, etc.

Python is an "acceptable" name, but Newton1 (or Newton3) would be a
great name. Shouldn't a great language have a great name? I think so.
And I think Python3000 is a great opportunity to give it a great name.

Of course, if Guido disagrees, I can always use

ok, i see...  python has a concept i'm not accustomed to which i found
described here:

http://zephyrfalcon.org/labs/python_pitfalls.html
4. Class attributes vs instance attributes

so i'm sure what is going on is obvious to experienced python
programmers...  i'm not really sure how to get around this though.  i'll
need to spend some time on reworking our models code i guess...  i
inherited this from someone, and what he was trying to do was to set
default values for objects representing tables (in kind of a simple ORM
layer) and storing the values in a dict, and when the object is
instantiated, the table is queried and the default dict values are
overwritten.  so obviously this method is not going to work as such..

sorry for the misdirection, i didn't quite understand at first..

ok, i see...  python has a concept i'm not accustomed to which i found
described here:

http://zephyrfalcon.org/labs/python_pitfalls.html
4. Class attributes vs instance attributes

so i'm sure what is going on is obvious to experienced python
programmers...  i'm not really sure how to get around this though.  i'll
need to spend some time on reworking our models code i guess...  i
inherited this from someone, and what he was trying to do was to set
default values for objects representing tables (in kind of a simple ORM
layer) and storing the values in a dict, and when the object is
instantiated, the table is queried and the default dict values are
overwritten.  so obviously this method is not going to work as such..

sorry for the misdirection, i didn't quite understand at first..

Multiple Windows in Pygame, using true concurrency in python via Kamaelia

[Michael Sparks]

Hi,


Just thought some people may be interested to hear that I've recently been
looking at adding true concurrency into Kamaelia, by using Paul Boddie's
pprocess as the core mechanism to allow us to run multiple Kamaelia systems
in the same app. (Since we have thread based, and co-operative generator
based components, process based is the next logical step)

   [1] http://kamaelia.sourceforge.net/Home
   [2] http://pypi.python.org/pypi/pprocess

Anyhow, first proof of concept is to take a _relatively_ non-trivial app and
a library hostile to being run in a single process and run it across
multiple processes trivially. (I can't test multicpu since I don't have a
multicpu machine, but this should work fine with a modern OS)

So the app I've chosen is a simple pygame based drawing/doodling app, and to
get it to launch 8 pygame windows from 1 app. Since neither SDL nor pygame
directly support this it struck me as not just a visible proof of concept,
but a useful one too (since pygame rocks! :-)

Anyhow, I've written up the code here and posted a screenshot here:
   http://yeoldeclue.com/cgi-bin/blog/blog.cgi?rm=viewpost&nodeid=1196129474

You'll note 8 pygame windows ... :-)

The original base test is here:
   http://yeoldeclue.com/cgi-bin/blog/blog.cgi?rm=viewpost&nodeid=1196029230

For those curious who don't like clicking on links, the code needed to allow
the 8 pygame windows looks like this:

  class SecondProcessBasedComponent(SimplestProcessComponent):
def main(self):
from Kamaelia.UI.Pygame.Display import PygameDisplay
from Kamaelia.UI.Pygame.MagnaDoodle import MagnaDoodle

X=PygameDisplay(width=200,height=200).activate()
PygameDisplay.setDisplayService(X)
MagnaDoodle().run()
yield 1

  exchange = SecondProcessBasedComponent().activate()
  R = []
  for _ in xrange(7):
 R.append(SecondProcessBasedComponent().activate())

So far, so good :-)

Incidentally, yes the project is alive and well, but a resource crunch
at work means I'm working on this only on my own time at the mo, which
means things like releases are having a longer cycle between them than
I'd like. Some recent developments include a greylisting proxy server,
a ER modelling tool and a (very) simple pygame based logo like tool for
teaching programming to small children. The webserver is aiming for WSGI
compliance, and the project also had a small number of students working
over the summer, assisting with some useful things like AIM/IRC integration,
the ability to use Kamaelia systems in non-Kamaelia based scripts/systems,
and looking at a sub-component model. (ie non-concurrent systems)

Is that REALLY what the code looks like?  Or does it actually look like
this:

  comments = []
  comment = models.comment()
  for row in rows:
  comment.author = row[1]
  comment.text = row[0]
  comments.append(comment)

That construct would produce exactly the result you describe.  You would
also get the result you describe if models.comment() were a normal function
that returns a single object, instead of a class name, as I have assumed.

There is not nearly enough information for us to diagnose the problem here.

Although it was a bit rude to choose the destructive form

C as it is and don't want their language overwritten!

Also there's the rather confusing fact that the value of

Yep, that's what I'm looking for.  Either a client that synchronizes message

Impossible:
(1) in "for word in words:" each word would end in "\n" and he'd have
to strip those and there's no evidence of that.

The answer is (1) he needs to supply a file of any kind for a start
[read the error messages that he got!!]
(2) despite the silence of the docs, it is necessary to have opened
the file in binary mode on systems where it makes a difference
(notably Windows)

[If the OP is still reading this thread, here's an example of how to
show a problem, with minimal code that reproduces the problem, and all
the output including the stack trace]

C:\junk>type dpkl.py
import pickle

d = {'and': [1, {'to': 1}], 'down': [1, {'upon': 1}], 'them': [1,
{'down':
1}], 'no': [1, {'others': 1}], 'this': [1, {'it': 1}], 'is': [2, {'a':
2}], 'upon': [1, {'a': 1}], 'it': [2, {'is': 2}], 'think': [2, {'and':
1, 'words': 1}], 'write': [1, {'this': 1}], 'to': [3, {'write': 1,
'put': 1, 'think': 1}], 'words': [1, {'no': 1}], 'others': [1,
{'think': 1}], 'put': [1, {'them': 1}], 'sin': [2, {'to': 2}]}

s = pickle.dumps(d, -1)
dnews = pickle.loads(s)
print "string", dnews == d

out = open("mchain.pkl",'wb')
pickle.dump(d, out, -1)
out.close()

f = open("mchain.pkl", "rb")
dnewb = pickle.load(f)
f.close()
print "load binary", dnewb == d

f = open("mchain.pkl", "r")
dnewa = pickle.load(f)
f.close()
print "load text", dnewa == d

C:\junk>python dpkl.py
string True
load binary True
Traceback (most recent call last):
  File "dpkl.py", line 24, in 
dnewa = pickle.load(f)
  File "c:\python25\lib\pickle.py", line 1370, in load
return Unpickler(file).load()
  File "c:\python25\lib\pickle.py", line 858, in load
dispatch[key](self)
  File "c:\python25\lib\pickle.py", line 1169, in load_binput
i = ord(self.read(1))
TypeError: ord() expected a character, but string of length 0 found

Changing the first line to
import cPickle as pickle
gives this:

C:\junk>python dpkl.py
string True
load binary True
Traceback (most recent call last):
  File "dpkl.py", line 24, in 
dnewa = pickle.load(f)
EOFError

Each of the two different errors indicate that reading was terminated
prematurely by the presence of the good ol' ^Z aka CPMEOF in the file:

>>> s = open('mchain.pkl', 'rb').read()
>>> s.find(chr(26))
179
>>> len(s)
363

You can count me in that large proportion. 8^)

By the way, after thinking about it a bit, here's a good name for
Python3000:

Newton1

The appended 1 serves to disambiguate the name from that of a late,
great scientist. It could be called N1 for short.

The 1 also serves to identify the major version. If it ever undergoes
a major revision (as in Python3000), it could then be called Newton2,
but that would not be done more than once per decade or so.

The docs for pickle.load(file) say """
Read a string from the open file object file and interpret it as a
pickle data stream, reconstructing and returning the original object
hierarchy. This is equivalent to Unpickler(file).load().

file must have two methods, a read() method that takes an integer
argument, and a readline() method that requires no arguments. Both
methods should return a string. Thus file can be a file object opened
for reading, a StringIO object, or any other custom object that meets
this interface.
"""

The error message(s) [plural??] that you are getting suggest(s) that
the argument that you supplied was *not* an open file object nor
anything else with both a read and readline method. Open the file in
binary mode ('rb') and pass the result to pickle.load.

It could be a file, in which case its iterator method would read lines
from the file and cause that error message.  But I think the answer is
that the pickle itself needs to be opened in binary mode, as someone

Wht??
self.words is obviously an iterable (can you see "for word in
self.words" in his code?), probably just a list.
self.words.count looks like a standard sequence method to me.
self.words.count(word) will return an int -- can you see all those
"[1,", "[2," etc in his printed dict output?

Should be, but a large proportion of the population pronounce it so

Are you opening the file in binary mode ("rb") before doing pickle.load on it?

Amazing what you can find in obscure corners of the obscure docs! BTW,
how many folks know what "bijective" means ?

Hmmm ... the encode is documented as "Produce a string that is
suitable as Unicode literal in Python source code", but it *isn't*
suitable. A Unicode literal is u'blah', this gives just blah. Worse,
it leaves the caller to nut out how to escape apostrophes and quotes:

>>> test = u'Python\'\'\'\'\"\"\"\"\u1234\n'
>>> print repr(test)
u'Python\'\'\'\'\u1234\n'
>>> print test.encode('unicode-escape')
Python\u1234\n
>>>

Why would someone bother writing this codec when repr() does the job
properly?

Anyhow, here's a solution to the OP's stated problem from first
principles using basic building blocks:

>>> line = '\\u0050\\u0079\\u0074\\u0068\\u006f\\u006e\n'
>>> u''.join(unichr(int(x, 16)) for x in line.split(r'\u') if x and x != '\n') 
>>> + u'\n'
u'Python\n'

Pickling dictionaries containing dictionaries: failing, recursion-style!

[lysdexia]

I'm having great fun playing with Markov chains. I am making a
dictionary of all the words in a given  string, getting a count of how
many appearances word1 makes in the string, getting a list of all the
word2s that follow each appearance of  word1 and a count of how many
times word2 appears in the string as well. (I know I should probably
be only counting how many times word2 actually follows word1, but as I
said, I'm having great fun playing ...)


printed output of the dictionary looks like so:

{'and': [1, {'to': 1}], 'down': [1, {'upon': 1}], 'them': [1, {'down':
1}], 'no': [1, {'others': 1}], 'this': [1, {'it': 1}], 'is': [2, {'a':
2}], 'upon': [1, {'a': 1}], 'it': [2, {'is': 2}], 'think': [2, {'and':
1, 'words': 1}], 'write': [1, {'this': 1}], 'to': [3, {'write': 1,
'put': 1, 'think': 1}], 'words': [1, {'no': 1}], 'others': [1,
{'think': 1}], 'put': [1, {'them': 1}], 'sin': [2, {'to': 2}]}

Here's the actual function.

def assembleVocab(self):
  self.wordDB = {}
  for word in self.words:
try:
  if not word in self.wordDB.keys():
wordsWeights = {}
afterwords =  [self.words[i + 1] for i, e in
enumerate(self.words) if e == word]
for aw in afterwords:
  if not aw in wordsWeights.keys():
wordsWeights[aw] = afterwords.count(aw)
self.wordDB[word] = [self.words.count(word), wordsWeights]
except:
  pass
  out = open("mchain.pkl",'wb')
  pickle.dump(self.wordDB, out, -1)
  out.close()

My problem is, I can't seem to get it to unpickle. When I attempt to
load the
saved data, I get:

AttributeError: 'tuple' object has no attribute 'readline'

with pickle, and

TypeError: argument must have 'read' and 'readline' attributes

Looking at the pickle pages on docs.python.org, I see that I am
indeed
supposed to be able to pickle ``tuples, lists, sets, and dictionaries
containing only picklable objects''.

I'm sure I'm missing something obvious.  Clues?

To answer indirectly, usually the EAFP (easier to ask forgiveness than

None. None of them are good names by my criteria. But then, a name is
only a name. One of the few names I like is Pascal, because he was a
great mathematician and scientist.

After thinking about it a bit, here are examples of what I would
consider a good name for a programming language:

Newton#
Newton*
Newton+

Newton was a great scientist, and his name is easy to spell and
pronounce. The trailing character serves to disambiguate it from
Newton in online searches. For shorthand in online discussions, N#,
N*, or N+ could be used as aliases.

Names of other great scientists, mathematicians, or computer
scientists could also be used, of course. Take your pick.

That's not a persuasive argument.

First of all, Python is named for a comedy troupe from England.  For
comparison, Perl is named for a knitting technique, Lisp is named for a
speech impediment, Ruby is named for a rock, Smalltalk is named for a
not-so-useful form of communication, and Java is named after a beverage
or an island.  

Which of those is a good name for a programming language by your
criterion?  I like the name Python.  It has a nice ring to it, and has
connotations that are simultaneously badass and humorous.  

For that matter, why name sneakers after a goddess of justice?  Why name
a car after a planet/resort town/rodent/mountain?

Because brand names are supposed to be memorable, not meaningful.

Cheers,
Cliff

No, I haven't, but I do know for a fact that the only location of the module
found is where I think it is.  There are no other modules on the system (or
in the search path) named _modulename.

That was in the original code to silently ignore things like a README file
or a directory that didn't have a __init__.py file.  The code I posted was
from my benchmarking script.  The code in the framework does a listdir()
and goes through that list trying to import.  We'll probably "smarten up"
that code a bit, but for now it works.

A directory and a file that aren't referenced in my test, but are
in the framework's import attempts (see listdir() comment above). 
Regardless, setting sys.path to just one directory speeds up both the
benchmark and the framework.

As I said above, no I haven't, but I will just to double check.

On Linux, print x, x.__name__ produces the expected result whether I have
one element in sys.path or all of them. On Windows, same result.

I don't know, but it does.  Right now, we're just importing empty modules. 
Once those modules have imports of their own, my "fix" will probably fall
apart, and we'll be back to square one.

> What directory tree walking?? Should be none

I know, that's the crazy thing...there should be no directory tree walking
or other filesystem activity after finding the module.  But setting
sys.path to one element does make a difference; that can be seen.  I don't
know the internal implementation of __import__, so I can't really comment
beyond my results.  Maybe I need to strace a python run.

> Are you sure the modules

'' would be whereever I start the benchmark script (~/bin), or whereever the
framework is started from, probably from the web server's home directory,
or from ~/bin when I'm profiling the framework.

Thanks for your responses.  I still trying to figure this out too. :)

Think about proposing its use to someone who has never heard of it

snake. Why should a programming language be named after a snake?

No.

I know that. But "C" was already a dumb name, and "C++" compounded the
dumbness. Actually, "C" was probably intended as a temporary name for
internal use, but not for a widely used, standard language.

Right, except that it should be return 0 (or preferably return False)
unless you want inverted logic.

Change to return 1/True (inverted) or return 0/False (not inverted)

Change "return 3" to "raise", so the exception gets propagated.

> return 0

Again, if you do not want the logic to be inverted, use return 1/True
instead

Well, that much is obvious.  What's probably not so obvious is *why*
the "variable thingy" is not initialized.  From what I can tell, this
could only happen if, and only if, PfFlagArrSize <= 0.  In that case,
the body of the for loop will never execute and PfFlag will *not* be
set, hence the error.

CoCoPy Beta released

[Ron Provost]

I would like to introduce CoCo/r to the Python world.  CoCo/r is an scanner 
generator and LL(k) parser generator which has already been ported to many 
languages.  CocoPy 1.0.3b1 can be found in the Python Package Index.

Features:
- The generated scanner and parser are completely independant.  Either is 
easily replaced by handwritten equivalents.

- The syntax for the target language specification is reminicent of the Pascal 
family of languages.

- The production syntax is not the usual UNIX regular expression syntax.  
Instead, CoCo uses the much more readable EBNF syntax introduced by Nicholas 
Wirth.  This same syntax is used for writing productions for both the regular 
(token syntax) and context free (phrase or statement syntax) grammars.

- The specification language supports botn inherited and synthetic attributes; 
as well as embedding semantic actions throughout a production.

- The generated scanners are DFAs.

- The generated parsers are recursive descent (hence the /r in CoCo/r)

- Features like comments and case (in)sensativity are handled automatically.

- Lexemes may be context dependant.

- CoCo provides a unique and easy to use error recovery system; a difficult 
problem in recursive descent parsers.

- The developer can customize error messages and event include his own.

What follows is a very simplistic example compiler included in the distribution.

How to read strings cantaining escape character from a file and use it as escape sequences?

[slomo]

How to read strings cantaining escape character from a file and use it
as escape sequences?

for example, a file 'unicodes.txt' has contents:

\u0050\u0079\u0074\u0068\u006f\u006e

Now,

>>> file = open('unicodes.txt')
>>> line = file.readline()
>>> line
'\\u0050\\u0079\\u0074\\u0068\\u006f\\u006e\n'
>>> print line
\u0050\u0079\u0074\u0068\u006f\u006e

But I want to get a string:

"\u0050\u0079\u0074\u0068\u006f\u006e"

How do you make it?

In this case, odbchelper.py is a module you are trying to import.

http://docs.python.org/tut/node8.html

One suggestion is to make a directory in your /home dir where you keep
your downloaded and homemade Python modules and scripts. I call mine
"Python" so it's ~/Python or /home/rick/Python.

Then, as suggested, add this dir to your Python path, so that you can
import your custom modules (with import odbchelper).

You may also want to add that dir to your system path, so that you can
call your Python scripts from anywhere without having to change back
to the ~/Python directory:

export PATH=~/Python:~/bin:$PATH

Here I've added two directories: Python and bin to $Path so that the
system knows to look for executables there.

Good luck.

Well, the language was going to be called "One of the cross beams
has gone out askew on the treadle" but that was a little unwieldy
and hard to understand when mumbled in a hury.  Searching for the
runtime "ootcbhgoaott" returns zero hits on Google.  That would
have guaranteed that the only hits that came back related to the
language.  However typing things like

 sh$ ootcbhgoaott myprog.ootcbhgoaott

became too cumbersome.  So they decided on Python instead.

Besides...nobody expected a kind of Spanish Inquisition...

(assuming "kind of tips")

I stuck "explorer command line options" into Google and... Bingo!
(All right, I'm cheating a bit: I knew that explorer *had* command
line options because I've been around a bit).

I remember reading an interview with a young woman who danced with a python
across her shoulders and down her arms. The interviewer asked if she was
afraid when she danced. She replied that she was afraid that the python
would go to sleep if she didn't keep him moving.

No. How would you pronounce it? Pai-tn?

Why don't you create a fork where the only difference is the name?

Why not? 

BTW, is "Windows" a great name for an operating system?

Really "unique" names; the OP wouldn't be happy about it when using
google ;)

It's "C incremented".

os.access() under windows

[Yann Leboulanger]

Hi,

Under Windows XP os.access has a strange behaviour:

I create a folder test under e:

then os.access('e:\\test', os.W_OK) returns True. Everything's ok.

Now I move My Documents to this e:\test folder

Then os.access('e:\\test', os.W_OK) returns False !!

but this works:
f = open('e:\\test\\test', 'a')
f.write('abc')
f.close()

So why os.access returns False ?

Re: 25 MOST FREQUENTLY ASKED QUESTIONS ABOUT ISLAM

[farsheed]

No , I tell you in brief what exactlly Islam is. (I know this is now a
good location but excuse me this time)

I was muslem for 25 years and happily not now. I read quran (muslem's
book) every day and it is full of inhuman words.
rozbeh(salman) and mohhamad made this book to **ck their people. if
you are a muslem you probebly be angry when you read this comment but
search about the rozbeh(salman) and his powerfull influence on
muhammad. muhammad had 40 wifes (**cking ***hole) and killed too many
poeple that you can't imagine. ali also was a killer and they all
where super super terrorists.

keep this in your mind:

20% of world is real
80% is what you made in your mind.

At one stage, "Monty Python's Flying Circus" was going to be called

If that had eventuated, then presumably we would all be disussing the Owl
