[Tutor] re Binding Event

working.
The he() is working well but clicking on the frame has no result.

frame.bind("", callback)
frame.pack()
self.button=Button(root,text='quit',fg='red',command=frame.quit)

Should this not be self.callback?

This looks like a method? Although the indentation is messed up

Re: [Tutor] help with loop that is to be fed out of a word list
"David" wrote
def uses_all(word, required):
for letter in required:
if letter not in word:
return False
return True
Now, I want to feed this code a list of words. This is what I have
so far:
def uses_all(required):
It is usually better to leave things that work alone.
You could have renamed the original finction then used it
in your new one. That would make the code much simpler.
fin = open('words.txt')
for line in fin:
word = line.strip()
if old_uses_all(word, required)
print word
But as ever its better to return a value from a function rather
than print from inside so i'd make your new function:
def uses_all(required, wordfile="wordlist.txt"):
words = []
for line in open(wordfile):
word = line.strip()
if old_uses_all(word, required)
words.append(word)
return words
required = raw_input("what letters have to be used? ")
print required
for word in uses_all(required)
print word
The code runs, but does not print the words. All I get it the output
of
the 'print required' command:
I realise that my loop fails to execute beyond the first word in the
list ("aa"), but why?
Look at your code:
def uses_all(required):
fin = open('words.txt')
for line in fin:
word = line.strip()
for letter in required:
if letter not in word:
# print "False!"
return False
return exits the function so the first letter you find that is not in
a word you will exit.

I think the only reliable way to parse all the citations correctly, in
the absence of "magic word" is to have a list of names. It involves a bit
of manual work, but should be good enough if there are a small number of
cases that is cited a lot of times.
>>> names = '|'.join(['Carter', 'Jury Commision of Greene County', 'Lathe
Turner', 'Fouche'])
>>> rep = '|'.join(['.*?'])
>>> dd = {'names': names, 'publ': rep}

Unless your program doesn't wait for any input before quitting.Then you just
have to add a line like this:
raw_input("Press to quit")
and that will block until you hit return.

A few issues here:
S.A. - this is hard, to allow this while filtering out sentences
R.J. O'Brien, etc. - Loosening up the rules for the second name can allow these
1517-18 - allow page ranges
The name issues are getting to be too much for me. Attached is a PLY
version that just pulls out the citation without the name; at one
point you indicated that would work for you.

To me, the context of a mailing list warrants the use of Reply-All to
the list, since a mailing list is typically meant to be a group
discussion. In this configuration, it takes extra effort to reply
privately, which is exactly the sort of thing you'd want to promote in

Kent The citation without the name is perfect (and this appears to be how most citation parsers work). There are two issues in the test run: 1. The parallel citation 422 U.S. 490, 499 n. 10, 95 S.Ct. 2197, 2205 n. 10, 45 L.Ed.2d 343 (1975) is resolved as: 422 U.S. 490 (1975) 499 n. 10 (1975) 95 S.Ct. 2197 (1975) 2205 n. 10 (1975) 45 L.Ed.2d 343 (1975) instead of as: 422 U.S. 490, 499 n. 10 (1975) 95 S.Ct. 2197, 2205 n. 10 (1975) 45 L.Ed.2d 343 (1975) ie. parsing the second page references should pick up all alphanumeric chars between the commas. 2. It doesn't parse the last citation ie. 463 U.S. 29, 43, 103 S.Ct. 2856, 2867, 77 L.Ed.2d 443 (1983). I tested it on another sample text and it missed the last citation too. Thanks!

In python (and many other languages) some special characters that are not easy
to represent have a code:
LF : \n
CR : \r
TAB : \t
So just add \n to to first line to add an eol: Text = "Hello World.\n" [Beware
that inside python \n actually both means char #10 and 'newline',
transparently, whatever the os uses as 'newline' code for text files. Very
handy.]
Alternatively, as you seem to be used to web codes, you can have hexa
representation \x0a or even octal \012

Well, the problem you are getting is probably a ValueError, meaning that the number of items does not match the expected number: >>> a, b = 1, 2, 3 Traceback (most recent call last): File "", line 1, in ValueError: too many values to unpack >>> a, b, c, d = 1, 2, 3 Traceback (most recent call last): File "", line 1, in ValueError: need more than 3 values to unpack Assuming that you want to have empty strings as the default you can use: a, b, c = (line.split() + ["", ""])[:3] Ok, step by step: line.split() produces a list with at least one string, assuming that line is a string. line.split() + ["", ""] creates a new list with two empty strings added to the end. [:3] gives you the first three strings of that list. Generally speaking, the above should be only used when you really really know that you want to threat your data such a way (ignore all later fields, add empty strings), it has a real potential for later debugging pains, when the data turns out to be different than what you expected. Another way would be: a, b, c = "defaultA", "defaultB", "defaultC" try: flds = line.split() a = flds[0] b = flds[1] c = flds[2] except IndexError: pass That still ignores any errors coming your way, usually it's better to check on len(flds). Generally, defensive programming (as in processing ANY data given, e.g. HTML parsing in browsers) is sometimes necessary, but often not such a good idea (one usually prefers an error message than faulty output data. Nothing more embarrasing then contacting your customers to tell them that the billing program was faulty and you billed them to much the last two years *g*). Andreas > > Moos > > P.S.

[Tutor] can't import Danny.OOo.OOoLib.py

I found several ways and I was able to get some of them to work. But I found the Danny.OOo.OOoLib.py tools (kind of old 2005 but still on the wiki) and was hoping I could try them. I placed the Danny.OOo.OOoLib.py file into my local folder and attempted to import. It immediately fails with the following message: ImportError: No module named Danny.OOo.OOoLib So could someone enlighten me as to why it reports this error?
