[Tutor] name 'x" is not defined
hi, I'm a linguist and absolut new on Python; I'm trying to follow the first chapter of *Natural Language Processing in Python. I'm aware this is a very basic question, but I'm stuck; can someone explain me, what does it mean that a function is not defined and how to proceed? * For example, for fdist: >> for word in nltk.corpus.brown.words(): if fdist(word)>= 3: print(word) I get the following: Traceback (most recent call last): File "", line 2, in if fdist(word)>= 3: NameError: name 'fdist' is not defined Thanks in advance! carme ___ Tutor maillist - Tutor@python.org http://mail.python.org/mailman/listinfo/tutor

You have to tell it, either by defining an fdist() function yourself (using def) or by importing a module that includes it.

See http://hkn.eecs.berkeley.edu/~dyoo/python/idle_intro/ Look for the section that starts, "Now that we've paddled long enough, we might be asking: ok, this is neat, but if we close down Python and start it up again, how do we get the computer to remember what we typed?"

It doesn't work to set the User-Agent header this way. See

for a recipe.

What content do you get? Is it an error message? What does wireshark
show for this request?

I don't think that has anything to do with your problem. httpOnly is
set by the server and interpreted by the browser. The Python change
was to allow httpOnly to be set by servers written in Python.

[Tutor] automatically generate python/pylons documentation
hi! I'm trying to generate documentation for my pylons web application. my personal opinion: 1. pudge: I've reviewed pudge. it was not very useful & hard to know as most of the links are not working on the site and lack of support. 2. epydoc I liked epydoc, the generated document looks more like what is generate by ruby tools, i guess rdoc. if i give it a single python file it works fine. but if i want epydoc to go into a specific folder & generate the documentation for all the files & files in the sub directories, it doesn't automatically do that. any pointers there. 3. sphinx: i've read a little about it. haven't tried it yet. my objective is to automatically generate documentation for my entire pylons webapp or any other python application. regds, arun. ___ Tutor maillist - Tutor@python.org http://mail.python.org/mailman/listinfo/tutor

Re: [Tutor] name 'x" is not defined
"carme colominas" <[EMAIL PROTECTED]> wrote I'm a linguist and absolut new on Python; I'm trying to follow the first chapter of *Natural Language Processing in Python. I'm not familiar witrh it but if the code you have is from the first chapter then I suggest you should go through one of the beginner Python tutorials first. You don't say whether you know any other programjing languages but from your question it doesn't look like it so I'll suggest you try the Non Programmers tutorials: http://wiki.python.org/moin/BeginnersGuide/NonProgrammers what does it mean that a function is not defined and how to proceed? Traceback (most recent call last): File "", line 2, in if fdist(word)>= 3: NameError: name 'fdist' is not defined Note that it doesn't say the function is not defined it says the *name* is not defined. That's a different thing. These kinds of details matter in programming. A name can be as variable or a function or a class or a module or most any other kind of object in Python. Names have to be created before they are used in Python. In this case it is a function and we create it by defining the function or by importing the function from another module. The other possibility is to access it from another module which we have already imported - like you did with the words() function: nltk.corpus.brown.words() You may just need to preface the fdist() function with the name of the module where it is defined. But all of this will makemuch more sense if you go through one of the tutorials on the link above. -- Alan Gauld Author of the Learn to Program web site http://www.freenetpages.co.uk/hp/alan.gauld ___ Tutor maillist - Tutor@python.org http://mail.python.org/mailman/listinfo/tutor

Wayne Watson wrote: I posted a query on sci.physics (newsgroup) on this question. I'll get back if anything useful pops up. Try Amazon with a search on python science, or whatever, as a title. You might try Google and search for high school physics python. There are some pretty advanced HS around the country that might have attempted something like you propose. My guess though is that you will have to construct a course pretty much from scratch. It should be interesting. Personally, I think technology should be left out, and one should concentrate on physics without math or technology. However, that's not easy. I think a famous physicist said something like think about physics not math. (Perhaps he was thinking about energy. We really don't know what it is, but the concept and math works. It's important to understand the abstraction.) I suspect the real motivation of the physicist was to create a concept, and then turn it into a new kind of math, for example, as Feynman did. Just an opinion. In any case, good luck. Ken Oliver wrote: For a starting place, you may want to look at "Mathematics for the Digital Age and Programming in Python" by Maria and Gary Litvin.
