Localized strftime()
Hi! I'm trying to get a localized date format from strftime() but it seems that is doesn't have any parameters for that or any information about this issue in Python docs. For example I want to turn this: 19 Oct, 2005 to this(slovene language): 19 Okt, 2005 Thanks for help, Sebastjan -- http://mail.python.org/mailman/listinfo/python-list

Dictionary string parser
Hi, is there any library or some way to parse dictionary string with list, string and int objects into a real Python dictionary? For example: >>> my_dict = dict_parser("{'test':'123','hehe':['hooray',1]}") I could use eval() but it's not very fast nor secure.

PIL and ImageMagick scalability
Hi everyone! I have a question about image processing. We have a website which will process a lot of images a day.It will be running Apache(worker) with mod_python. My question is what should we use for processing. If we use PIL the processing will be done with the same process that handles other requests and that will probably slow them down when there will be a peak. If we use ImageMagick you create new process that does the image processing which probably uses multiple CPUs better and is more scalable, right? Thanks, Sebastjan -- http://mail.python.org/mailman/listinfo/python-list

Re: encoding problem
I think you are trying to concatenate a unicode string with regular one so when it tries to convert the regular string to unicode with ASCII(default one) encoding it fails. First find out which of these strings is regular and how it was encoded, then you can decode it like this(if regular string is diff): mailbody +=diff.decode('') Sebastjan On 3/3/06, Yves Glodt <[EMAIL PROTECTED]> wrote: > Hi list, > > > Playing with the great pysvn I get this problem: > > > Traceback (most recent call last): >File "D:\avn\mail.py", line 80, in ? > mailbody += diff > UnicodeDecodeError: 'ascii' codec can't decode byte 0xe9 in position > 10710: ordinal not in range(128) > > > > It seems the pysvn.client.diff function returns "bytes" (as I read in > the changelog of pysvn: http://svn.haxx.se/dev/archive-2005-10/0466.shtml) > > How can I convert this string so that I can contatenate it to my > "regular" string? > > > Best regards, > Yves > -- > http://mail.python.org/mailman/listinfo/python-list > -- http://mail.python.org/mailman/listinfo/python-list

I see, intuitively one would think it would try to get it from global context as it's not yet bound in the local. Thanks for the explanation.

Re: imap folder scanner
A very simple example... import imaplib m = imap.IMAP4() m.login(username,password) m.select('myfolder') status, data = m.search(None,'(SUBJECT "BIKES")') assert status=='OK', "Error. Message: %s"%data data = data[0] #you get your results in a list and search returns only one result assert data,"No results" #cool, we have results, but IMAP's search command only returns IDs so we have to fetch #msgs now status,senders = m.fetch(data.replace(' ',','),'(BODY.PEEK[HEADER.FIELDS (FROM)])') assert status=='OK', "Error. Message: %s"%data Now you just have to parse the "senders" data. There are many examples about sending emails with python, like this one: def send_notice(): import smtplib msg = 'we got your mail, indeed' from email.MIMEText import MIMEText mail = MIMEText(msg, 'plain', 'utf-8') mail['From'] =fro='[EMAIL PROTECTED]' mail['Subject'] = "Spam machine" mail['To'] = to = '[EMAIL PROTECTED]' server = smtplib.SMTP('localhost') errors = server.sendmail(fro, to, mail.as_string()) server.quit() That other program should be very simple to make now.

"senders" is list, that is why that regex does not work.
