[Tutor] Help! Pickle file
This may sound silly, but when writing a program where there is a pickle file, how does that get included into the entire program? For instance; to create a new pickle file.. #!/usr/bin/python # Filename: pickling.py import cPickle as p #import pickle as p (snipped from python.org) Does this fall anywhere in the program in particular?

[Tutor] Key Error
Sorry, this is probably too general a question, but I can't find any specific information on it. What exactly is a "key error" and how do I clear it? I entered something like this: abcd=h[key]['ABCD'] and when I run it I'm getting KeyError: 'ABCD' What does this mean? Thanks! - Shape Yahoo! in your own image.

Re: [Tutor] Key Error
Probably best if I skip the example and show what code I do have:
~~~
for key in h.keys():
wssd=h[key]['WSSD']
wspd=h[key]['WSPD']
wmax=h[key]['WMAX']
newi=h[key]['NEWI']
if wssd<-989. or wspd<-989. or wmax<-989.: break
if wspd==0.: break
~
Where the "newi" = "abcd" that I showed before. I have no where else in my
code anything pertaining to these 4 keys. The first 3 were there, and produce
no errors. I am making adjustments to an existing script. I only have C
programming knowledge so my thought was that it "newi" was just a variable that
needed to be assigned. You'll notice the parameters below (i.e., if wssd <
-989 ) but there is obviously nothing for "newi" at the moment. The program's
only error at the moment seems to be this line:
newi=h[key]['NEWI']
But as you can see, the other items are set up the same way.
Thanks bundles!!!

Hi Sara,
It means you've tried to access a data structure (most likely a
dictionary) with a key that does not exist in that structure. Witness
>>> my_dict={42:"Six times seven", 1: "The loneliest number"}
>>> my_dict[42]
'Six times seven'
>>> my_dict['42']
Traceback (most recent call last):
File "", line 1, in
KeyError: '42'
>>> my_dict[17]
Traceback (most recent call last):
File "", line 1, in
KeyError: 17
>>>
It isn't a question of `clearing' it, but of tracking down the wrong
assumption behind your code. It may be that you thought you were using
a key you'd added before and were wrong (my_dict['42'] as opposed to
my_dict[42] shows a common source of that).
But, from your
> abcd=h[key]['ABCD']
I'm guessing that you've got the key-access syntax a bit wrong. Did
you mean
abcd = h['ABCD']
instead?
HTH,

Re: [Tutor] Key Error
I appologize...but what is, 'grep'? I'm at the end of my rope, which right now looks about as sturdy as string (and I don't mean a string buffer either)!!! Okay, where to go from here... Again, as I mentioned there may be holes in what I'm giving but that's because 1). segments of this program do work, and I don't want to overload this list with my Python problems (and believe me, I have enough to probably keep you kind, knowledgable folks busy for weeks!) and 2). I don't always know if I'm giving you all enough information to decipher my mess, or too much information. I believe 'NEWI' is supposed to be a new subkey that will hold a value called 'newind.' But if I can't get the program to initialize this 'NEWI' then I don't know how any values can come from it. Thanks anyways...

OK, Then that is telling us that h is a dictionary containing further dictionaries inside. The error tells us that at least one of the dictionaries does not have a key 'NEWI' If this code is supposed to be production strength it is not of good quality. It should either be defending these dictionary accesses with a try/except block or it should be using the get() method of the dictionary to force a default value. (The tests at the end are poorly written too. If one of my team produced code like this I'd be having strong words with them!) Which is the best solution will depend on the situation... > I have no where else in my code anything pertaining to > these 4 keys.

You need to find why that data is missing. Or, you could find a valid default value and assign that, either through a try/except block or by uysing a get() instead of key access. -- Alan Gauld Author of the Learn to Program web site http://www.freenetpages.co.uk/hp/alan.gauld - Get the Yahoo! toolbar and be alerted to new email wherever you're surfing. ___ Tutor maillist - Tutor@python.org http://mail.python.org/mailman/listinfo/tutor

I brought this up with Kent a little while ago...

What happens if I need to sort alphabetical and numerically?
I guess in this case it would be
('Fred', 20), ('Joe', 50), ('Kent', 80), ('Sara', 90)
I'm taking the original list and the original values
i.e., ('Fred', 20), ('Joe', 90), ('Kent', 80)... and switching it so that it
reads in both ways...
List 1, [('Fred', 20), ('Joe', 90), ('Kent', 50), ('Sara', 80)]
List 2, ('Fred', 20), ('Joe', 50), ('Kent', 80), ('Sara', 90)]
How would I do that so I wind up with both lists? I have two lists now, but
if I try and reorder them they just reverse in alphabetical order without
affecting the second value (the number).
Thanks!

Re: [Tutor] Bundle help!
Sorry to be so confusing. Just realized a dumb mistake I made. It doesn't
need to be resorted alphabetically and numerically. I need one list
alphabetical and one numerical.
(Alphabetical) List 1, [('Fred', 20), ('Joe', 90), ('Kent', 50), ('Sara',
80)]
(Numerical) List 2, [('Fred', 20), ('Kent', 50), ('Sara', 80) ('Joe', 90)]
It looks like these are appended together, but to re-sort, how do I (not sure
if this is a word) "unappend" them?

You can supply your own comparison function to the sort routine.
You can also just specify the key to sort by for simple cases.

But you lost me here. You seem to be switching the values

Re: [Tutor] Bundle help!
Sorry, just needing to clarify. As I may have eluded to in other posts, this is sort of a script that was written and I'm making modifications to. Due to my serious lack of experience, I'm afraid to rewrite anything. However, would I accomplish the same result by copying the lists, then breaking them apart with zip()? I haven't used that before, but I'm willing to try it as long as I don't ruin what's already been done. Unfortunately, the link you posted didn't bring up anything. I tried to search google groups and got a bunch of asian text (using comp.lang.py). Again, sorry for my lack of experience here. I do speak C somewhat.

This is probably a long shot given the code you've posted so far,
but I don't suppose there are any design documents available?
Structure charets, class diagrams? Even plain text or pseudo
code?
Not sure I follow what you mean by those specific documents or diagrams, but
I do have the output and the sample code. Seems like it would be easy to just
enter it all in and get that output, except for the different files I've had to
include ("chmod" command on various scripts). Not sure if I've described that
correctly. Nonetheless, I've had to bundle this and pickle that and create 3
different files plus one script. Only close on one of those. If you are
talking about the output on this one step, I can put it into a text file and
attach it. Again my fear is that whatever I do to make that happen will
eventually lead to the other outputs as well.
In an ideal world it would be possible to find the faulty function
without having to read any code, but few projects are that well
documented. But then again few projects have nothing! If you
can find it it might tell you at a high level how the code hangs
together.
I'm not sure zip is the best tool for breaking lists apart,
but I'm no expert with it. But its easy to do with a simple
loop if you are dealing with a list of tuples:
list1 = []
list2 = []
for item in theList:
list1.append(item[0])
list2.append(item[1])
I will give this a try and some of the other suggestions I have received.
Thanks again!

Re: [Tutor] Bundle help!
Thanks to everyone for your help and quick responses!
Has anyone heard of the "bundle method?" Some of you have already said you
didn't. I wonder why it's included as part of my code/instructions. I'm
trying to accomplish what I 'think' they want with the other questions I've
posed here.

#SUB-TASK 1: Fix the above to print/write only the keys with >0% missing,
sorted alphabetically
#by the key. (No need to use the "bundle method" for that). But ALSO append the
#same information to outfile2, sorted by worst offender. (Use bundle for that).
Just curious, but in this link ('
http://xahlee.org/perl-python/sort_list.html ') you mentioned, what does the
"re" part mean? At first I thought it was the name of the list or 'return' but
that's included later.
***

import re
def getNum(str): return float(re.findall(r'\d+',str)[0])
return cmp(getNum(x),getNum(y))

Re: [Tutor] interpreter restarts
Luke, Jacob, et. al...
Dumb question (may be slightly off course from what you two were discussing),
but are you both describing how to get the IDLE to run along with the editor?
I may just be getting too many things confused. I've tried to run IDLE, but
that's not working. I have the same function through opening it separately
from the Start menu but then it doesn't work as IDLE should work with the
editor (or so I've been told that happens). I can type the word Python in my
editor and it comes up, but then the editor is gone. I've gone so long with
just SSH, but at this point it's worth it if I find a way that makes sense. As
someone mentioned from this list, at least it'll be code that is easier to read
for a newbie like myself.
(Hope that didn't confuse or cause unnecessary headaches...)

It sounds like python_icon.exe is a fake executable that just contains
the icon for python programs...
hence the name.
You probably stumbled across the path to the icon to use, instead of the
path that is used when running the 'Edit with IDLE' thing.
Try this:
open an Explorer window, via Start Button -> Run -> explorer {ENTER}
or your favorite method. Use the My Computer shortcut if you want,
either way.
Now hit "Alt, t, o" to browse to the Tools -> Folder Options menu setting.
Go to the File Types tab, and scroll down till you find "PY"
click the Advanced button.
You should now see a dialog box with Edit with IDLE listed under actions.
Click Edit when "Edit with IDLE" is selected.
in the "Application used to perform action:" field you should see
something like this:
"C:\Python24\pythonw.exe" "C:\Python24\Lib\idlelib\idle.pyw" -n -e "%1"
Basically, this is the same as saying:
python idle.py
except it's more verbose because python may not be on your path (and
pythonw is used instead of python so there's no dos box)
As you will notice, there are some parameters there at the end.
the -n is the one you're interested in .
-n means no subprocess.
Just remove that, and you will have a subprocess on the 'Edit with IDLE'
feature.
There is some caveat here - it doesn't work correctly on some systems,
I'm told.
I've never had problems changing this, but I don't recommend it to
people randomly just in case it were to cause problems for them.
Then I'd feel bad.
But since you asked, I thought I'd give you all the info you need.
HTH,

Re: [Tutor] IDLE Usage - was Interpreter Restarts
First off, yes, I was referring to (I guess you could say) a non-python editor. I use an SSH editor set up by my school. If I type python at the prompt in SSH, I get the Python shell. My problem is, I can't open a GUI no matter what I subscribe to or purchase. I have Python 2.3 and yes, I can access the commandline, but that does not work the way it's been described to work. If this still doesn't make any sense, just ignore me... Sara >>Not quite what we were discussing, but I think you may have given just enough clues that i can be of some help. Just for reference ~ which editor are you using? IDLE is both an editor and a python shell or interpreter. It is not the same thing as typing python.exe wherever you might be typing it. Typing Python into an editor should put the word "Python" into your currently open file. I don't believe that this is what you mean. Perhaps you are confusing what exactly is an editor? You use Windows you've mentioned before. So here's what you can do. Start -> Programs -> Python 2.5 -> Python (commandline) This is the python interpreter. As you might already know. And then this. Start -> Programs -> Python 2.5 -> IDLE (Python GUI) This is IDLE. As you probably know. Two windows should come up when you click IDLE. One is an editor. The other is the python shell, or interpreter. You can open .py files in IDLE by right clicking and selecting "Edit with IDLE". At any time that you wish to run a program that is open in the editor half of IDLE, hit F5 and the Python shell half of IDLE comes to the top and runs the program. If doing all that doesn't do what I expect it to do, or you have something else in mind, reply back. If it does, then great! Oh. And tell me which editor you are using which magically opens a python interpreter when you type Python into it. ;-) JS ___ Tutor maillist - Tutor@python.org http://mail.python.org/mailman/listinfo/tutor It's here!

Re: [Tutor] IDLE Usage - was Interpreter Restarts
Everyone who has commented... I have XWin32It hasn't worked. I've talked to some people in the IT departments and they've given me things to check (boxes to check or uncheck) and that doesn't seem to make a difference. When I picked up these projects I was given a lot of stuff and left to figure it out. I was also left with the impression that I should have the GUI working. If a lot of Python programmers use SSH, then I guess there is no problem. But when you're a newbie who really doesn't understand what they're doing, anything that might make the process a tad more straight-forward is worth it. For example, I worked on this basic Unix editor 'Pico' before I learned I could switch to Vi and have my code color-coordinated so that I knew where my comments were and I could see if I accidentally commented something out that needs to be there. So maybe it's not too important that I use the Python shell with my school's editor program open (as I was advised to do). Some of you have already seen my confusion from the different questions I've asked about my code (or rather, the code I've been editing). So I thought most of the Python programmers preferred to use IDLE and that maybe it would simplify things just a tad for me. I'm about 2000 miles away from where I should be with these projects.

I'm not sure what your problem is. Does the SSH program provide a file transfer utility? could you write your code on your local computer then just transfer the final code to the server? A lot of Python programmers use Vi for writing their code. do you have access to that through SSH?

Re: [Tutor] IDLE Usage - was Interpreter Restarts
- Original Message From: Robert H. Haener IV [EMAIL PROTECTED] If you name the SSH client (which I believe you've been calling an "SSH editor") you're using, I might be able to give you step by step instructions for setting your client to use X Forwarding. If the SSH server doesn't allow X Forwarding, I recommend using a program called 'screen'. Basically, 'screen' allows you to use a shell a bit like the tabbed browsing in Firefox (or Opera, IE7, etc.) by creating a framework wherein you can create new virtual shells and switch between them using keyboard shortcuts. What is more, you can label the virtual shells and even copy/paste text between them. I can give you plenty of information about using 'screen' if you want it, what I'm getting around to is that if I was in your situation I would have the python interpreter running in one virtual shell whilst running vim in another virtual shell. That's pretty much what I was attempting. I was advised to mark the "Tunneling" box (TunnelingX11 Connections), and it's checked. I don't see the X Forwarding option, however. Under that same tab I checked for anything else system-wise that would pertain and I don't see anything. Again, I have XWin32 installed, but I probably need to renew it or somehow get it to work as you've described.

Re: [Tutor] IDLE Usage - was Interpreter Restarts
Alan, Actually, I think you just solved one of the main issues I've had. That is, trying to figure out how much it'll help to have the GUI session open with the SSH session (as was recommended when I set out to do these projects). I had it in my mind that having this up and working would mean that these projects would make more sense. I could have been using two SSH sessions all along, I suppose. Another concern was more towards the specific nature of these projects, once I have to concern myself with graphics on a few tasks. For all I know it may not matter either way, but I had to check. I've been talking to someone else off list about that. Anyways, thanks for help!

OK, Personally I'd forget about a GUI, its not that big a win for Python IMHO. What I'd do instead is open two SSH sessions, in one of them I'd open a vim session (or emacs if you prefer) to edit my code. In the second window open a python interactive session for testing stuff. You can also use Unix job control to background this session if you need to test the scripts, or you can open a third SSH session with a Unix shell prompt. In practice that's how I do nearly all my serious Python programming on Windows - using 3 separate windows: vim, Pyhon and shell. Try ideas out in the Python session, copy those ideas into the editor and save the file and then run the code in the shell window. Repeat as needed. > I have Python 2.3 and yes, I can access the commandline, but that > does > not work the way it's been described to work. What is missing? It should work like any standard >>> prompt. However it will be the vanilla version without some of the nice extras that IDE shells often provide and depending on how your Python was built it may not offer GNU readline capability to recall previous commands etc. Finally, If you really want to run an X GUI I'd recommend getting cygwin. Its big but it includes a near complete Unix/ X environment for your PC (including the fonts) as well as an SSH client and provi8ded your SSH server allows X to run - and many don't for security reasons - then it should work. You will have to issue the xhosts incantations of course to tell the server to accept requests from your PC. Pesonally I think its more work than is worth it unless you will be doing a lot of work on that server over a long time..

On the style front, if you want to force a result to a float it's more
conventional to use the float() conversion function:

And comparing to 0.0 doesn't really add anything except two

Argghh!!! No, no, no! Attribute Error! No matter how much data you have in
the file, you will *never* be able to call sort on it, because file objects
do not understand sort. They do not have the "attribute" called "sort".
Lists have sort. If you want to sort them like you are trying, you will have
to convert the file into a list (of lines).
lst = list(outfile2)
lst.sort()

Re: [Tutor] attribute error - quick addition
No luck finding tutors. I don't make enough. It seems to be this script that's throwing me off. But I understand and I'll take what I've learned to date and something will work eventually. Thanks for your concern and support.

I'm still learning about lists, tuples, etc... Sarah, You've been hanging around with this list for a few weeks now. If you just took one day out to go through the official tutorial then you should know enough to answer all of these questions. Seriously, invest the time to learn the language and you will cut the time messing around and solve your problem a lot sooner. Hacking away in the hope of stumbling on a solution and asking questions here if it doesn't work is one of the most inefficient ways to get your job done. (Both for you and us!) We are all here to help people learn Python and answer questions but you will make it easier on all of us if you work through a tutor to get the basics clearly fixed. Not only will your problem be easier to solve but the answers we give will make more sense too!
