Perhaps it's just bad wordplay from me.  I assumed you knew that
'heading' was a misspelt 'heeding' but you playingly used literally
"heading" in your reply.  For those who didn't get understand that,
though, I offered the correct "heeding" and then rhyming with "soccer
ball", I presented myself as the sucker who offered the correct spelling
when _it was not needed_.

So I didn't think I was heeding a sucker call at any moment, I just
wrote that as a pun.  There were no indirect accusations about your
post, if that is what you meant.

When I was 6 yrs old, Google was inexistant.  It isn't anymore, so my

1.

(a{3})(?:b[ab]*)?$

This finds the first (leftmost) "aaa" either at the end of the string or
followed by 'b' and then arbitrary sequences of 'a' and 'b'.

This will also match "" (from second position on).

2.

If you insist in only three 'a's and you can add the constraint that:

* let s be the "arbitrary sequence of characters" at the start of your
searched text
* len(s) >= 1 and not s.endswith('a')

then you'll have this reg.ex.

(?<=[^a])(a{3})(?:b[ab]*)?$

3.

If you want to allow for a possible empty "arbitrary sequence of characters"
at the start and you don't mind search speed

^(?:.?*[^a])?(a{3})(?:b[ab]*)?$

This should cover you:

>>> s="xayzbaaa123aaabbab"
>>> r=re.compile(r"^(?:.*?[^a])?(a{3})(?:b[ab]*)?$")
>>> m= r.match(s)
>>> m.group(1)
'aaa'
>>> m.start(1)
11
>>> s[11:]
'aaabbab'

Applying my last regex to your test cases:

You're right, Fredrik, but we (graciously as a group :) take also notice of
the other requirements that the OP has provided elsewhere and that are not
covered by the simple test that he specified.

The code above works for "b" too, which the OP has already ruled out,
and it doesn't work for "aaa".

Here I object to either you or your need for a regular expression.  You see,
before the "aaa" in your second test case, you have an "arbitrary sequence

You said the filename comes as data, and not as contents of os.listdir(),
right?

You can only know (for almost certain) what encoding is *not* the filename
(by looping over encodings and marking those where .decode fails).  

If it was textual data, you could be more successful in guessing (btw, it's
been a long time since I requested example texts from various encodings for
my encoding-guessing app, but I was sent only one) by testing characters in
pairs and their frequencies.

I suspect that you have more than one large arrays (lists?) that

I never said "google it".  I presume you mean this post as a reply to all

Steve Holden does know how to help people here, something that can be proven
if you google for previous posts of him.

>groups.google was made to help! not to say google it!

groups.google was made to *archive* newsgroups. By using groups.google, you
just participate in the larger community of Usenet.  Google that strange
term "usenet".  It's kind of public email.  You send to a "newsgroup", then
everybody in the world can see your message, and anybody can reply, and so
forth.

You'll see in one of the top hits (for "usenet") that Google sometime
acquired the Usenet Archive of Deja (Deja.com, DejaNews.com etc), which are
archives of newsgroups since before Google existed.  There is no company
"google.groups" full of professionals getting paid to answer your questions.

Think of groups.google as an agency that allows you to travel in the
dangerous world of Usenet.

>i really dont not what kind of professional you are to say "google it!"

Assuming you reply to Steve Holden; you have false logic.  Like I said,
nobody ever gets paid for replying to newsgroup posts, so professionalism
does not get involved in any sense.  Or have you sent any money to the PSF
[Python Software Foundation] asking for support?  If that is the case, I
fully apologize, and please don't read the rest of my post! ;)

Your writing style hints you are 14-15 yrs old, but you can also be some
non-native English speaker (as I am), even an IT professional (the topic of
LDAP does not concern the average adolescent :); in either case, perhaps you
might be able and not entirely bored to read more than a few pages:

http://www.catb.org/~esr/faqs/smart-questions.html

Let this be your guide in your travels in Usenet.  Show you did your
"homework" before asking others.

You see, imagine yourself after about 15-20 years of using computers and
discussing them with others (in private or on the internet), and new people
keep coming all the time asking the same questions that have been discussed,
answered and beaten to death dozens of times before.  Steve's using
computers for longer than that, and he bothered at least to tell you the
obvious step you didn't take: to google your question so you find the
previous related discussions.

You should thank him for offering his time, because his reply was helpful
even if you don't understand it; he directed you to the whereabouts of the
answer to your question.  Ask groups.google about

group:comp.lang.python ldap

and work your way from there.  When you come back here after you've grokked
the "Smart Questions" document, I (and Steve I am sure, and lots of others
who didn't bother to reply as Steve did) will be more than glad to help you
further your knowledge of Python.

I am on the side of advocating SPF records --and I am one of the first
four postmasters in my country's TLD that set up SPF records for two of
the email domains I'm administrating.  SPF is an internet draft now.[1]

Your method is/will_not be free (as in beer), as hinted in
http://www.ece.arizona.edu/~edatools/home/email/registry/Form-Sender01.htm
.  *That* is a drawback similar to the licensing of the Microsoft's
Sender/Caller-ID scheme.  Why not support open, free standards?

I have developped scripts of my own to perform various consistency
checks (including SPF lookup) and maintain my own black list (I am
consulting three RBL's which I have found to be close to my standards,
but I want to avoid excessive usage of their bandwidth), and although it
takes some time almost every day overseeing things, I would be very
timid to support such a free (as in jazz :) scheme.  I mean, the
"reputation" idea is nice, but paying for this reputation won't help its
spreading.

Good luck with it as a business, though.

You might start having troubles, though, as soon as SPF checks get more
widespread.

Say your work mail is [EMAIL PROTECTED], and your private mail is
[EMAIL PROTECTED]; if you send email through your office mail server
with the envelope "MAIL FROM: [EMAIL PROTECTED]", then some (and
eventually many) receiving servers shall ask yagoohoogle.com for their
SPF record, and since your office mail server won't probably show up as
a valid email sender from yagoohoogle.com , your email will get
rejected.

That's a good thing.

Overload the __or__ special function (ie the 'pipe' operator) instead of the
__gt__ operator.

sinks) but I couldn't find it in google.groups.com --I think Aahz had
something to do with it, but ICBW.

The problem with the operators chaining is that ">" is treated differently
than "|".  Check the following disassembly:

>>> import dis
>>> dis.dis(compile("a>   24 ROT_TWO 
 25 POP_TOP 
>>   26 RETURN_VALUE
>>> dis.dis(compile("a|b|c", "", "eval"))
  0   0 LOAD_NAME0 (a)
  3 LOAD_NAME1 (b)
  6 BINARY_OR   
  7 LOAD_NAME2 (c)
 10 BINARY_OR   
 11 RETURN_VALUE


The comparison operators include some logic in order to "do what I mean" (so
that 4" operator, just don't chain it, in order to
avoid such unexpected behaviour.

I think that you haven't grasped the fact that a chain of calls of a
recursive function needs a return for *every* invocation of the function
(but I could be wrong :)

Check the following function, analogous to your own:

>>> def f(x):
if x > 4:
print "   returning", x
return x
else:
print "   start recursion"
f(x+1)
print "   end recursion"


>>> print f(0)
   start recursion
   start recursion
   start recursion
   start recursion
   start recursion
   returning 5
   end recursion
   end recursion
   end recursion
   end recursion
   end recursion
None

Do you see why the function returns None?

The difference between art and pornography, as I perceive it, is that you
don't have to think about it when you see pornography.  You can even turn
off the audio in cinematographic/video pornography and still the message
comes through (in the vague lines of "jerk off along").

So, in pornography there's no interpretation step involved; therefore, by
pure logic, all "compiled to machine code" languages should be looked down
upon as pornographic, and Python is art.  QED.


PS You (the READER) are licensed to substitute other "non compiled to

just do it outside comp.lang.python (the COMPANY).  We don't care what you

Just for those who don't know, in general *nix operating systems (and the

because obviously is the path separator, and '\0' because it's the

As a word of caution: the OP is checking for the permissions of an
*existing* file.  Both Juho's and Sybren's suggestions *destroy* the file's
contents.

So, VJ, I'd suggest the following change:

Open the file for read write

outfile= open(outfilename, "r+b") # I assume binary

and later on catch errors in .write operations.

I see someone suggested imgseek.  This uses a Haar transform to compare
images (check on it).  I did make a module based on imgseek, and together
with PIL, I manage my archive of email attachments (it's incredible how many
different versions of the same picture people send you: gif, jpg in
different sizes etc) and it works fairly well.

E-mail me if you want the module, I don't think I have it currently online

To quote a Google reply:

"IPv6 multicast addresses are distinguished from unicast addresses by the
value of the high-order octet of the addresses: a value of 0xFF (binary
) identifies an address as a multicast address; any other value
identifies an address as a unicast address."

Actually, it should go to the CheeseShop, since it is a python module that
is a bridge between PIL and the C module (I don't believe multi-file modules
are appropriate for the cookbook, but ICBW); however, my web space is out of
reach for some months now (in a web server at a previous company I worked
for), and I'm in the process of fixing that :)

There's a TreeWidget.py module in idlelib, which you can modify to your
needs.  There's also the Tix.Tree widget, if you have Tix installed (and you
probably do if you run a recent Python on your Windows box), which also is
very powerful.

His code was indented fine, as you maybe noticed later on.  The actual

other newsreaders too) did not show indentation.

Fredrik suggested already the typical "use spaces, not tabs"; I just thought
that "lack of indentation" was unfair for the OP.

Anything to do with recent rumours about license change?  Will programming

pleasing after all, it should be illegal)?  There will be a charge per line

This works (unless there are long network timeouts, when downloading...),
but another idea is to wait for the existence of a zero-byte sentinel file
that is created last, after the transfer (or process, in general) has ended.

This method is the one that has worked best for me.

Try

and then this *might* work for you:

month_as_string= "Jan"
time.strptime(month_as_string, "%b").tm_mon

"Localization" (as Fredrik also suggested) is the reason for the *might* in

Well, either port your system out of the window or port tput.c to your
