Tkinter documentation (Was: What does "batteries are included" mean?)
by Martin v. Loewis Jan. 24, 2001

Jan. 24, 2001

> It's already a blot on Python that the standard documentation set > doesn't cover Tkinter. Just point your friendly web browser to Ping's HTML generator and ask for Tkinter, or invoke "pydoc.py Tkinter". [I wouldn't have brought this up if it hadn't been the contribution of my friend Nils Fischbeck:-] Regards, Martin

BROWSER status
by Eric S. Raymond Jan. 24, 2001

Jan. 24, 2001

I spent the morning writing and testing patches to make urlview and GNU Emacs BROWSER-aware, and have sent them off to the relevant maintainers. I've also sent a patch to Andries Brouwer for the environ(5) man page. Those of you interested in my latest bit of social engineering can take a look at http://www.tuxedo.org/~esr/BROWSER/ A bow in Guido's direction -- if he hadn't been grouchy about this I probably wouldn't have gotten to shipping those patches for a while. -- <a href="… [View More]

re: sets
by Greg Wilson Jan. 24, 2001

Jan. 24, 2001

1. I did a poll overnight by email of 22 friends and colleagues, none of whom are regular Python users (yet). My question was, "Would you expect the interface of a set class to be like the interface of a vector or list, or like the interface of a map or hash?" 15 people have replied; all 15 have said, "map or hash". Several respondents are Perl hackers, so I'm sure the answer is influenced by previous exposure to the set-as-valueless-hash idiom. Still, I think 15-0 is a pretty … [View More]

Is X a (sequence|mapping)?
by Martin v. Loewis Jan. 24, 2001

Jan. 24, 2001

> i don't see an easy way to test if something supports one of these > abstract interfaces in Python. Why do you want to test for that? If you have an algorithm that only operates on integer-indexed things, what can you do if the test fails? So it is always better to just use the object in the algorithm, and let it break with an exception if somebody passes a bad object. Regards, Martin

Sets: elt in dict, lst.include

The only change that needs to be made to support sets of immutable elements is to provide "in" on dictionaries. The rest is then all quite natural: dict[key] = 1 if key in dict: ... for key in dict: ... (Then we can also get rid of the ugly has_key method.) For those that need mutable set elements badly enough to sacrifice a little … [View More]

getting rid of ucnhash
by Fredrik Lundh Jan. 24, 2001

Jan. 24, 2001

It's probably just me, but the names of the two unicode modules tend to irritate me: > ls u*.pyd ucnhash.pyd unicodedata.pyd (the former contains names, the latter data) I've been meaning to rename the former, but I just realized that it might be better to get rid of it completely, and move its functionality into the unicodedata module. The result is a single 200k unicodedata module, which con- tains the name database as well as two new functions: name(character [, default]) =&… [View More]
