Re: [Tutor] cgi scripts
Bt "Crash", I mean the browser displays: Internal Server Error The server encountered an internal error or misconfiguration and was unable to complete your request. The code I sent before had a silly mistake in it. Here is a better example of the things I am trying and failing at. I can print a single key. I can iterate over the keys, just printing out "hello" for each iteration. But I can't figure out how to iterate over all the keys printing out somethinf sensible. #!C:\python25\python.exe import cgi, sys # import cgitb; cgitb.enable() #Send errors to browser sys.stderr = sys.stdout #Parse data from form data = cgi.FieldStorage() #Send response to browser print "Content-type: text/html\n" print "CGI Form Response\n" print "This is the data passed to the cgi script" # This next bit works and I can see a list of keys displayed in the browser print "Version 4: data.keys()\n" print "" print data.keys() # This next bit also works and I can see the value of the variable "JQuiz_q01_score" print "-" print "JQuiz_q01_score = ", data["JQuiz_q01_score"].value # However, whenever I try to iterate over all the keys, I get the "Internal Server error" print "-" for k in data.keys(): print ""data[k].key # I have also tried data[k] #data.key[k] #data[k].value # and many other random combinations. ___ Tutor maillist - Tutor@python.org http://mail.python.org/mailman/listinfo/tutor

Re: [Tutor] cgi scripts
Thanks guys, This works :) field_list = '\n' for field in data.keys(): field_list = field_list + '%s : %s\n' % (field, data[field].value) field_list = field_list + '\n' print field_list I think the problem wasn't in getting the keys and values, but I might have been producing illegal HTML code before. I think I'd better brush up on my HTML skills. Jim Alan Gauld wrote: "Jim Morcombe" <[EMAIL PROTECTED]> wrote The code I sent before had a silly mistake in it.

Poorly formed HTML won't give an internal server error. That is due to something more serious such as a syntax error in your program. With bad HTML you will see *something* in the browser, even if only a blank page, and you can view source to see the actual code.

Re: [Tutor] gnuplot from a python gui
[EMAIL PROTECTED] a écrit : Hello tutors, I'm trying to generate a plot using gnuplot from within a python gui. In Windows, if after the plot is drawn I use a raw_input string demanding a 'RETURN' be hit, the plot will persist on the screen until the 'RETURN' is pressed. In *nix, one can use the 'persist' switch to easily and much more elegantly accomplish the same. My question is, is there a better way IN WINDOWS to keep the plot on the screen rather than having to leave the gui and find the console window in which a 'RETURN' must be pressed to continue? My gui will not 'quit' until I enter the 'RETURN' in the console window. Kind of a chintzy way to end the gui, really. There must be a better way than using raw_input??? Daniel B. Maybe a stupid question: as your application has a GUI, why do you use this raw_input() trick? As far as I know, this is a way to let the console open at the end of execution so that the user can watch results (otherwise it's autom. closed). What's the point in doing that in a GUI app?

[Tutor] Upgrading from Python 2.5 to Python 2.6 - IDLE not working...
Hi All, This is my first post, so I apologize in advance for any etiquette violations. I am interested in learning Python, and to that end, I undertook to upgrade my current version of Python 2.5 (available via openSUSE repositories and YaST) to Python 2.6. I have Python 2.6 running (compiled from source [I'm not a total bonehead]) but idle gives me the following when I invoke it in bash: [EMAIL PROTECTED]:~> idle Traceback (most recent call last): File "/usr/local/bin/idle", line 3, in from idlelib.PyShell import main File "/usr/local/lib/python2.6/idlelib/PyShell.py", line 14, in import macosxSupport File "/usr/local/lib/python2.6/idlelib/macosxSupport.py", line 6, in import Tkinter File "/usr/local/lib/python2.6/lib-tk/Tkinter.py", line 39, in import _tkinter # If this fails your Python may not be configured for Tk ImportError: No module named _tkinter [EMAIL PROTECTED]:~> I thought of unistalling and reinstalling (using YaST) the associated Python packages to make them aware of the version change, but the Idle package says it requires Python 2.5.2, nothing more or less, so I didn't attempt it. Thanks in advance for your patience.

I'm confused by the import macosxSupport. There is a known problem with IDLE on MacOSX: http://bugs.python.org/issue4017 For linux I think there is a build option to include tkinter but someone else will have to answer that one.

Re: [Tutor] Question
Last I checked, Notepad ++ works with Python. I've never used it for Python, so I don't know how it works.
