win32com python AttributeError!
by Michael March 31, 2009

March 31, 2009

Hi Python-list - Has anyone figured this out from Rebecca: Hi, I am having trouble with win32com for python. I get the following error when I try to issue any command after using Dispatch. >>> xl=win32com.client.Dispatch("Excel.Application") >>> xl.Visible=0 Traceback (most recent call last): File "<pyshell#7>", line 1, in ? xl.Visible=0 File "D:\Python22\Lib\site-packages\win32com\client\dynamic.py", line 504, in __setattr__ raise AttributeError, "Property '%s.%s' can not be set." % (self._username_, attr) AttributeError: Property 'Excel.Application.Visible' can not be set. >>> I have programs that I used to use all the time and they simply won't run. Is this an error with python or win32com or my setup? Thanks, -rebecca I have the same problem. Thus, myWord = Dispatch("Word.Application") myWord.Visible = 1 # or, True opens a word document but myExcel = Dispatch("Excel.Application") myExcel.Visible = 1 # or, True causes (as Rebecca notes above): AttributeError: Property 'Excel.Application.Visible' can not be set. Thanks, Michael

Detecting Binary content in files
by ritu March 31, 2009

March 31, 2009

Hi, I'm wondering if Python has a utility to detect binary content in files? Or if anyone has any ideas on how that can be accomplished? I haven't been able to find any useful information to accomplish this (my other option is to fire off a perl script from within m python script that will tell me whether the file is binary), so any pointers will be appreciated. Thanks, Ritu

make money!!!!
by filmmaker March 31, 2009

March 31, 2009

THE PAYPAL $6 DOLLAR MONEY-MAKING METHOD: This is all you need: 1) An email address 2) A Pay Pal account 3) Then POST, POST, POST.......... Ever since the internet became popular, the word "scam" has become a daily term. I have never once tried any moneymaking "system" outside of this because of that very reason. However, after reading reports on the validity and reputation of this money making system HERE IS HOW IT WORKS... There is a list of 6 email addresses (you’ll see it as you read further). When someone new comes along (such as yourself) he/she removes 1 off of the list, moves the other five email addresses up one position (i.e. 6 goes to 5, 5 to 4, etc.), and adds their Pay Pal email address in the 6 position. This process is what develops the power of compounding. The bottom line is this... Honesty and Integrity creates Profitability. Following this EXACT process is what creates the money, and that is why this system has been raved about. Altering the system creates weak results. The legality of this system comes from the idea that you are of course creating a mailing list, and a "service" is being provided (more on that later.) INSTRUCTIONS: STEP 1: The first thing to do COPY, PASTE and SAVE this entire post in word or notepad on your computer so you can come back to it later. After that, if you are not already a Pay Pal user you need to go to the Pay Pal website at https://www. paypal. com/ and SIGN UP. To receive credit card payments from other people you must sign up for a PREMIER or BUSINESS account (not just a PERSONAL account). This is highly recommended to allow others easy payment options. To place the initial $6 into your account, you will have to verify your bank account with PAYPAL (which may take a few days). PAYPAL is 100% secure and is used by millions of people worldwide. STEP 2: Here is where the action occurs. Next send a $1.00 payment to each of the 6 email addresses on the current list from your Pay Pal account. To do this quickly and successfully, follow these simple steps: 1. Login to Pay Pal and click the "Send Money" tab near top of screen 2. In the "Recipient’s Email" field type: the email address 3. In the "Amount" field type: "1" (your $1.00 payment) 4. In the "Category" field select: "Service" (Keeping it legal) 5. In the "subject" field type: "EMAIL LIST", 6. In the "message" field type: "PLEASE PUT ME ON YOUR EMAIL LIST". (By doing this, you are creating a service and maintaining the legality of the system by "paying" for the service.) 7. Finally, click on the "Continue" button to complete the payment. 8. Repeat these steps for each of the 6 email addresses. That’s it! (By sending the $1.00 payment to each address, you are implementing the compounding POWER of the system. You will reap what you sow!) Here is the current e-mail list: ************************************************* The email list: 1) formicone(a)o2.co.uk 2) ravewillow(a)hotmail.com 3) haneefgroup(a)yahoo.com 4) kcarebear62(a)aol.com 5) raja12399(a)live.com 6) frob2(a)hotmail.com STEP 3: Now take the 1 email off of the list that you see above (from your saved file), move the other addresses up (6 becomes 5, 5 becomes 4, etc.) and add YOUR email address (the one used for your Pay Pal account) as number 6 on the list. This is the only part of the document that should be changed. **Make sure to use the email address you registered with Pay Pal** STEP 4: Change anything you need to, but try to keep this article as close to original as possible. Now, copy and paste your amended article to at least 200 new groups, message board. (I think there are 32,000 more groups) All you need is 200, but remember, the more you post, the more money you make-as well as everyone else on the list! Use your internet browser is to search for various news groups, on- line forums, message boards, bulletin boards, chat sites, discussions, discussion groups, on-line communities, etc. For example? Log on to any search engine like Yahoo. com or Google. com and type in a subject like ’MILLIONAIRE MESSAGE BOARD’, MONEY MAKING DISCUSSIONS’, ’MONEY MAKING FORUMS’, or ’BUSINESS MESSAGE BOARD’, etc. You will find thousands and thousands of message boards. Click them one by one and you will find the option to post a new message. Fill in the subject, which will be the header that everyone sees as they scroll through the list of postings in a particular group, and post the article with the NEW list of email addresses included. THAT’S IT!!! All you have to do is jump to different newsgroups and post away. After you get the hang of it, it will take about 60 seconds for each newsgroup. HOW THE MONEY WORKS: When you post 200 messages in various forums, it is estimated that at LEAST 15 people will respond and send you a $1.00 ($15.00). Those 15 will Post 200 Posts each and 225 people send you $1.00 ($225.00), etc. through 6 levels of email addresses. For comprehension purposes, here is an easy viewing chart: 1) 15(1) = 15 people ($1) = $15 2) 15(15) = 225 people ($1) = $225 3) 15(225) = 3375 people ($1) = $3,375 4) 15(3375) = 50625 people ($1) = $50,625 5) 15(50625) = 759375 people ($1) = $75,9375 REMEMBER... HONESTY AND INTEGRITY = PROFITABILITY YOUR NAME COULD CYCLE FOR A LONG TIME! THIS MAKES IT THE GIFT THAT KEEPS ON GIVING. REMEMBER, THE MORE NEWSGROUPS YOU POST IN, THE MORE MONEY YOU WILL MAKE!! GOOD LUCK!!

With perl, I'm thinking of doing something like the below: if ( ( -B $filename || $filename =~ /\.pdf$/ ) && -s $filename > 0 ) { return(1); } So my isbin method should return a true for any file that isn't entirely ASCII text, so I guess for my purposes classifying a unicode file as a 'binary' would be alright.

custom handler does not write to log file
by dj March 31, 2009

March 31, 2009

It seems that you can create custom handlers and add them to the logging.handlers namespace(http://mail.python.org/pipermail/python- list/2008-May/493826.html.) But for reasons beyond my understanding my log file (test.log) is not written to. #################### my handler class ####################################################### import logging.handlers # create my handler class class MyHandler(logging.handlers.RotatingFileHandler): def __init__(self, filename): logging.handlers.RotatingFileHandler.__init__(self, filename, maxBytes=10485760, backupCount=5) # Register handler in the "logging.handlers" namespace logging.handlers.MyHandler = MyHandler ################ test app.py ################################################################## import logging import logging.handlers from myhandler import MyHandler # log file path LOG_FILE_PATH='H:/python_experiments/logging/test.log' # log file path #log file formatter myformatter = logging.Formatter('%(asctime)s %(levelname)s %(filename) s %(lineno)d %(message)s') # setup a log instance for myHandler logger2 = logging.getLogger('myLog2') logger2.setLevel(logging.CRITICAL) hdlr2 = logging.handlers.MyHandler(LOG_FILE_PATH) hdlr2.setFormatter(myformatter) hdlr2.setLevel(logging.CRITICAL) logger2.addHandler(hdlr2) # give it a try print 'using myHandler' logger2.debug('this is a test of myHandler') print 'after logger using myHandler' Thanks in advance for your help.

regex negative lookbehind assertion not working correctly?
by Gabriel Rossetti March 31, 2009

March 31, 2009

Hello everyone, I am trying to write a regex pattern to match an ID in a URL only if it is not a given ID. Here's an example, the ID not to match is "14522XXX98", if my URL is "/profile.php?id=14522XXX99" I want it to match and if it's "/profile.php?id=14522XXX98" I want it not to. I tried this: >>> re.search(r"/profile.php\?id=(\d+)(?<!14522XXX98)", "/profile.php?id=14522XXX98").groups() ('14522XXX9',) which should not match, but it does, then I tried this : >>> re.search(r"/profile.php\?id=(\d+)(?<!14522XXX98)", "/profile.php?id=14522XXX99").groups() ('14522XXX99',) which should match and it does. I then tried uring /positive lookbehind assertion/ instead and it does this : >>> re.search(r"/profile.php\?id=(\d+)(?<=14522XXX98)", "/profile.php?id=14522XXX98").groups() ('14522XXX98',) which matches as it should and then I tried this : >>> re.search(r"/profile.php\?id=(\d+)(?<=14522XXX98)", "/profile.php?id=14522XXX99").groups() Traceback (most recent call last): File "<stdin>", line 1, in <module> AttributeError: 'NoneType' object has no attribute 'groups' which doesn't match as it should. Could someone please explain why the negative lookbehind assertion is not working as I understand it? Also, notice how the last digit of the first expression is not matched, I get ('14522XXX9',) instead of ('14522XXX98',), why? It does on the others.... Thank you, Gabriel
