ok but still i am not clear with my problem. if i test this one ============== kk ='how old are you' >>> len(kk) 15 ========== but in my case ========== >>> abebe = 'አበበ በሶ በላ' >>> len(abebe) 23 ========== why the lenght is 23 while I am expecting to be 9 only. becuase I have 9 characters(including space) just typed. there must be a kind of trick over it. thanks all Seid M On 10/30/08, python-list-request(a)python.org <python-list-request(a)python.org> wrote: > Send Python-list mailing list submissions to > python-list(a)python.org > > To subscribe or unsubscribe via the World Wide Web, visit > http://mail.python.org/mailman/listinfo/python-list > or, via email, send a message with subject or body 'help' to > python-list-request(a)python.org > > You can reach the person managing the list at > python-list-owner(a)python.org > > When replying, please edit your Subject line so it is more specific > than "Re: Contents of Python-list digest..." > -- "RABI ZIDNI ILMA"

download image from flickr.com

Oct. 30, 2008

Dear Pythoners, Could you please help me look at a code, which is to download image from flickr.com? I wish to download images from flickr.com automatically. You can get the code at http://cid-bbc15003189d7799.skydrive.live.com/self.aspx/Public/FImageCrawl.…. There is still some problem with the code. I do not know much about regular expression. There seems to be something wrong with the line of "compile_obj = re.compile(r'dyn.Img\(".*?",".*?",".*?","(.*?)"')". Could you please help me debug it? And I aslo hope to download the first 10 pages of the images, how can I do this? Thank you so much ! Good night!

Need some help speeding up this loop
by erikcw Oct. 30, 2008

Oct. 30, 2008

Hi all, I'm trying to write a loop that will build a list of "template strings". My current implementation is *really slow*. It took 15 minutes to finish. (final len(list) was about 16k entries.) #combinations = 12 small template strings ie "{{ city }}, {{ state }}..." #states = either a django model or a list of 50 states #cities = either a django model of 400 cities or a smaller list of cities. templates = [] for c in combinations: if len(states): for state in states: if type(geo) is City: cities = state.city_set.all() else: cities = geo for city in cities: if type(city) is City: city = city.city templates.append(c.template.replace('{{ city }}', city)) templates.append(c.template) #just in case there are no cities templates = [k.replace('{{ state }}', state.state).replace('{{ state_abbr }}', state.abbreviation) for k in templates] elif len(geo): for city in geo: templates.append(c.template.replace('{{ city }}', city)) else: #no cities or states so add roots templates.append(c.template) The final output needs to be a list of the templates combined with all the states and cities (some templates will only have the city, some only the state). Any ideas how I can optimize this? Thanks!

This typically gives you something that you could enter in any Python program. Note that e.g. the string 'አበበ በሶ በላ' is not suitable in any Python program, it requires an encoding where those characters are supported like e.g. UTF-8. Now, if you type "print X" on the commandline, it will output the thing as a string instead, giving you the original contents. If, like for a list, no string representation exists, it will fall back to using repr() instead. Disclaimer: I'm not a pro yet myself, but I think this covers the background a bit. Maybe someone will correct me if I'm horribly wrong. Uli -- Sator Laser GmbH Geschäftsführer: Thorsten Föcking, Amtsgericht Hamburg HR B62 932

Use an outer join like in my (generated) sql to fix that and "distinct" to suppress duplicate contact_id-s. The following should work with SQLite3: select distinct c.contact_id, a.value as address, t.value as telnumber, e.value as email from contacts as c left outer join contacts as a on c.contact_id = a.contact_id and a.field_id=1 left outer join contacts as t on c.contact_id = t.contact_id and t.field_id=2 left outer join contacts as e on c.contact_id = e.contact_id and e.field_id=3 Peter

Because lists represent their content in the `repr()` form. So you, the programmer, can see what's really in there. Ciao, Marc 'BlackJack' Rintsch
