How do Java interfaces translate to Python?
by Gordon Tyler Oct. 1, 2001

Oct. 1, 2001

Hi, I'm primarily a Java programmer but I dabble in Python on a regular basis. My current project is a low- and high-level interface to IRC which can be re-used to write IRC clients and bots. My question is this: Java being my primary language, I'm very used to using interfaces and I was wondering if there was an equivalent construct or idiom in Python? How does one do in Python what one would do with interfaces in Java? Thanks, Gordon

Have you tried to call manage_main instead of manage? This is normally the way if you try to look up Zope without a frame-capable browser.

MySQLdb where's fetchoneDict()?
by Gabriel Ambuehl Oct. 1, 2001

Oct. 1, 2001

-----BEGIN PGP SIGNED MESSAGE----- Hello, I wonder whether there's a fetchoneDict() equivalent to fetchallDict() in version 0.9 in case one wants to fetch only one row and thus don't want to have the data in a a list of dictionaries. (The reason I don't just want to use fetchone() is that I've got tables with some 20 fields and it's rather hard to handle that many fields in a tuple when you have only numerical indexes in order to access them...). cursors.py says I should use fetchone() instead as fetchoneDict() is deprecated for some reason not noted there. Ooh I just noticed that v 0.9 says that for all the fetch*Dict() calls, does that mean I've got to rewrite all code that was written using fetch*Dict() based on v0.3.5?

There used to be an explicit FAQ entry on this, in http://www.python.org/doc/FAQ.html entry 3.11 or thereabouts. It's gone now ;(. For older versions, you should be able to do something like this: make CFLAGS=-fpic mkdir .shared cd .shared ar xv ../libpython.a gcc -shared -o ../libpython.so *.o --titus

That is all true, but you deleted my main point, which is that given that the digest is in fact a bit string, is there any reason to avoid future-proofing against new algorithms that may not return a byte-integral number of bits? This *is* a PEP, after all. ;-) Also, algorithms such as MD5 are always specified as 128-bit, not 16-byte, so from a clarity standpoint (if not the most useful), bits make more sense to me. >>What exactly does update() do?

We're supposed to make it *LOOK* that way, yes, but, hey, deep down many of us aren't driven by *application needs* in tinkering with tools. At least, I know I am not, and I've known many other geeks who feel the same.

a new hope for office-tools scripting in Python...
by Alex Martelli Sept. 30, 2001

Sept. 30, 2001

Still in alpha, but...: http://www.linuxworld.com/site-stories/2001/0928.hancom.html ''' two layers of scripting that will be available in HancomOffice 2.0. One is aimed at programmers, and the other at non-technical users. All applications will share the ability to do raw Python scripting, which Gordon compares to Visual Basic. The apps will also share a more user-oriented scripting capability called AV, built on top of Python ''' This is all I know about it (I hit upon it while looking for a way to finally and definitively pension off MS Word and thus never have to boot into Windows any more -- unfortunately StarWord 5.2 isn't happy with O'Reilly's styles, sigh -- and HancomWord 2.0 is "farthest from release" according to the article, so I'll have to keep suffering for now...), but I thought some c.l.p readers could be as interested as I was. The 'Gordon' mentioned is CEO of theKompany as well as the new HancomWhatever firm that's making this HancomOffice multiplatform office suite, BTW. They're definitely not new to doing good Linux stuff, in other words:-). And I'm in love with KDE 2.2, but that's another story:-). Alex

Yes, exactly. My thinking is: "If you don't want a reply, you don't get one". And making it difficult to reply is a sure sign you don't want a reply. Also, most e-mail address collecting robots can automatically delete nospam etc. In case of doubt, they include both (or more) variations. (I sometimes even got spam addressed at Message-IDs - thanks to the mail catch-all on my domain). Two friends of mine just got their individual spam filtering method: The first one uses a mail address that contains nospam in two places: user.nospam(a)nospam.domain.tld. However, all four combinations (deleting none, either or both nospam) go to valid mail addresses, and are processed by the same MDA. All mails are delayed some time, and if a mail arrives at more than one address, it sorted into a special folder he sorts manually every week or so. The second, Nico, has an email catch-all on his subdomain, and his MTA and NNTP-Proxy generate a new, unique address for each outgoing message. Now, whenever an incoming mail arrives for more than 2 addresses, he deletes the first two deliveries, and the current and any further delivery attempt gets caught in a "teergrube". He had this in a test phase where he didn't delete his mails for 2 months, and he didn't catch any non-spam, and only two spams did pass. However, both setups need some sophisticated mail setup, and not everyone does have access to such one. markus -- "The strength of the Constitution lies entirely in the determination of each citizen to defend it.
