RE: Python CGI Script
by Iyer, Prasad C Oct. 2, 2005

I guess your python script isn't getting executed. a. I guess you might have to tweak the server if the script is not getting executed. b. Maybe your script is getting executed but you are not setting the "Content-type" parameter which is essential for browser that it is an html page. Note :- Set "Content-type" to "text/html" I guess this should work regards prasad chandrasekaran --- Cancer cures smoking -----Original Message----- From: Efrat Regev [mailto:efrat_regev@yahoo.com] Sent: Friday, September 30, 2005 4:20 PM To: python-list(a)python.org Subject: Python CGI Script Hello, I'm a data-structures course TA trying to write a python CGI script for automatically compiling and testing students' projects. Unfortunately, I've run into some questions while writing this, which I couldn't solve with the various (and helpful) python-CGI documentation. (It's possible that I'm posting to the wrong group; if so, I'd appreciate suggestions for the appropriate group.) 1. In my HTML page, I have the following: <form method="post" action="submission_processor.py" enctype="multipart/form-data"> .... </form> In the above, submission_processor.py is the python CGI script. I didn't write a URL in the action field, since I'm first testing everyting on a local machine (running FC4). The first line of submission_processor.py is #!/usr/bin/python and I've done chmod +x submission_processor.py When I hit the "submit" button, my browser (Firefox on FC4) doesn't run the script; it asks me whether it should open submission_processor.py or save it to disk. I couldn't figure out why. 2. My HTML page has the option for an instructor to list the various submissions and scores. Obviously, this should be inaccessible to students. The instructor has a password for doing this, therefore. Suppose I place the password inside a python script, and give this script only +x permission for others. Is this adequate as far as security?

gtk.TextView.move_mark_onscreen() broken?
by Tony Nelson Oct. 2, 2005

Oct. 2, 2005

Is gtk.TextView.move_mark_onscreen() broken? Perhaps only in Python's gtk module, in Python 2.3, gtk 2.4.14? I'm asking here because I'm using gtk from Python and don't want to write a C program to verify my issue. I've also tried gtk.TextView.scroll_to_mark() and gtk.TextView.place_cursor_onscreen(), and none of them want to do anything. The rest of my program works, so I'm not a complete gtk bazo. ________________________________________________________________________ TonyN.:' *firstname*nlsnews(a)georgea*lastname*.com ' <http://www.georgeanelson.com/>

Question about stdin and PATHEXT on Windows XP
by Lasse Vågsæther Karlsen Oct. 2, 2005

Oct. 2, 2005

I got a loop like this: while True: line = sys.stdin.readline() if not line: break line = line.rstrip() log_message(options.channel_name, line) print line this loop will read text if I execute it from a command prompt like this: dir | python.exe log.py however, since I've set PATHEXT to contain .PY, I tried this: dir | log.py which ended up with the loop just skipping. Does anyone know how to fix this problem ? Being able to use PATHEXT execution (just execute python file directly) and still being able to grab stdin? I assume that since there is some magic involved in invoking python.exe here, stdin gets munged on the way. -- Lasse Vågsæther Karlsen http://usinglvkblog.blogspot.com/ mailto:lasse@vkarlsen.no PGP KeyID: 0x2A42A1C2

Fair enough. I hadn't come across it as a programming construct until I hit Python. I'd seen the (presumable) precursor of set comprehension it in maths & formal methods before though. To help Xah along, this shows a //more nearly// correct version of his table function (his doesn't do anything like the spec). It works correctly for tables of the form: table("i", ("i",3)) table("i,j", ("i",3), ("j",3)) table("math.cos(i+j)", ("i",3), ("j",-3,3)) It doesn't produce quite the right structure when you have more than 2 iteration rules). Problems with this implementation: * mkrange() is not passed along the existing context. This means tables of the form: table("i,j", ("i",3), ("j",1,"i")) Won't work. This would require changing the mkRange function such that it's passed the most currently built environment. This is a relatively trivial change, which I'll leave for Xah. * The structure is incorrect for more than 2 iteration rules. I think I'm missing a simple/obvious trick in my mkTable._extend_table function. I'm not really fussed though. (It's clearly something dumb :) * It's not really clear which list nests which. It's possible the lists are nested the wrong way round. I'm fairly certain that the evalTable code will work fine when the mkTable code creates the right structure. I'll leave that to Xah to fix. It's somewhat further along than his original attempt though. (actually matches his spec for 1 or 2 iteration rules). def mkRange(listspec): if len(listspec)==2: return xrange(1,listspec[1]+1) elif len(listspec)==3: return xrange(listspec[1],listspec[2]+1) return [] def mkTable(ignore, *listspecs): def _extend_table(listspecs, result): if len(listspecs) == 0: return result else: listspec = listspecs[-1] listspecs = listspecs[:-1] r2 = [] for R_ in result: for R in R_: # SMELLY inner_result = [] for i in mkRange(listspec): inner_env2 = dict(R[1]) inner_env2[listspec[0]] = i inner_result.append( (ignore, inner_env2) ) r2.append(inner_result) result = _extend_table(listspecs, r2) return result return _extend_table(listspecs, [[(ignore,dict(globals()))]]) # SMELLY def evalTable(table): if len(table) ==0: return table else: result = [] for evallist in table: inner_result = [] for eval_args in evallist: try: r = eval(*eval_args) inner_result.append(r) except TypeError: inner_result.append(evalTable(eval_args)) result.append(inner_result) return result def table(ignore, *listspecs): abstract_table = mkTable(ignore, *listspecs) return evalTable(abstract_table) Example: >>> import math >>> table("math.cos(i+j)", ("i",3), ("j",-3,3)) [[-0.41614683654714241, 0.54030230586813977, 1.0], [0.54030230586813977, 1.0, 0.54030230586813977], [1.0, 0.54030230586813977, -0.41614683654714241], [0.54030230586813977, -0.41614683654714241, -0.98999249660044542], [-0.41614683654714241, -0.98999249660044542, -0.65364362086361194], [-0.98999249660044542, -0.65364362086361194, 0.28366218546322625], [-0.65364362086361194, 0.28366218546322625, 0.96017028665036597]] Regards, Michael.

struct.unpack
by g.franzkowiak Oct. 2, 2005

Oct. 2, 2005

Hello Everybody, I've read a pipe and store it in a object. My next step was the separation from 4 bytes with obj = string.join(list(dataObject)[:4] ==> '\x16 \x00 \x00 \x00' and the converting by value = struct.unpack('I', obj) generated the error "unpack str size does not match format" Unfortunately is len(obj) 7, but integer lengt 4. Why 7 ? Any ideas ? gf
