Can't create list of dictionaries
Hi there, I've got a function that returns a dictionary, I need to loop and return 1000 dictionaries and append them to a list, but the thing is that when I do the list.append(funtThatReturnsDict()) the resulting only ever has 1 dictionary attached to it, even after running the append function 1000 times! I've tried using dict.copy() on the dictionary that was returned from the function but this didn't work either. And the function is definately returning different dictionaries each time as I can see that when I print them. I know this is something to do with the dictionries being stored as references but I've no idea how to fix it seeing as the copy() function didn't work. Thanks! -- http://mail.python.org/mailman/listinfo/python-list
Best way to spawn process on back end computer
Hi, I'm running a python cgi script on a frontend web server and I want it to spawn another script (that takes a long time to run) on a backend number crunching server thats connected to the same network. What do you think is the best way to do this? I have a few ideas but I'm sure there is a "best" way to go about this. Thanks. -- http://mail.python.org/mailman/listinfo/python-list

As it happens I've managed to come up with a solution to this problem
using a subprocess rather than a thread. Its not exactly rocket
science but I thought I'd post it anyway. There are 3 files:
## dots.py ###
# a script to print a dot every half second until it is terminated
import time
import sys
while 1 == 1:
sys.stdout.write(".")
sys.stdout.flush()
time.sleep(.5)
# PrintDots.py ##
# This is a simple class to spawn off another process that prints dots
repeatedly on screen
# when printDots() is called and stops when stopDots is called. It is
useful in cgi-scripts
# where you may want to let the user know that something is happening,
rather than looking
# at a blank screen for a couple of minutes.
import time
import subprocess
import os
from signal import SIGTERM
class PrintDots:
# the constructor, called when an object is created.
def __init__(self):
self.pid = 0
# the location of the script that prints the dots
self.dotsScript = "dots.py"
def printDots(self):
self.pid = subprocess.Popen( [ "python", self.dotsScript] ).pid
def stopDots(self):
os.kill(self.pid, SIGTERM)
mainFile.py ##
# The above can then be called from any cgi-script as follows
from PrintDots import PrintDots
p = PrintDots()
p.printDots()
print "Doing R Stuff"
my_Call_To_R_That_Takes_A_Long_Time()
p.stopDots()
print "OK"
And low and behold dots are printed on screen every half second while
python is talking to R, with an output like this:
Doing R Stuff.OK

" is a call to an function in R (the statistical programming language) via Rpy (A python module that allows calls to R). The call takes a couple of minutes to execute. I'm trying to build a web front end to this R function and instead of the user looking at a blank screen for 2-3 mins, I want to print dots to let them feel like the program isn't hanging. What I am saying is that without the "time.sleep(.5)" line, the above code will print dots on the screen continuously for 2-3 mins, filling it up with a ridiculous ammount of dots. Whereas with the time.sleep line, instead of pausing for half a second between dots, its seems to print, as you correctly pointed out: . OK With a pause of 2-3 minutes between the . and the OK. I hope that clears things up a little. I haven't the faintest idea why the code above doesn't work but hope someone has an idea. It wouldn't be something to do with python not being able to handle multiple threads at the same time or something?

Spawing a thread and printing dots until it finishes
Hi, I'm trying to write a piece of code that spawns a thread and prints dots every half second until the thread spawned is finished. Code is something like this: import threading class MyThread ( threading.Thread ): def run ( self ): myLongCommand()... import time t = MyThread() t.start() while t.isAlive(): print "." time.sleep(.5) print "OK" The thing is this doesn't print a dot every half second. It just pauses for ages until the thread is finished and prints prints ".OK". But if I take out the "time.sleep(.5)" line it will keep printing dots really fast until the thread is finished. So it looks like its the time.sleep(.5) bit that is messing this up somehow? Any ideas? Thanks! -- http://mail.python.org/mailman/listinfo/python-list

Get cgi script to begin execution of another script...
I've posted something similar to this already, but now I'm more sure of what I'm asking. Basically I've a CGI script, that when executed by the user, I want to call another script that does a very long running task (10 hours +) and print a message on the screen saying that the user will be emailed on completion of the very long task. The script executing the very long task will then email the user on completion. So far I have something like this (leaving out the obvious)... CGI script: pid = subprocess.Popen(["python", "spawn.py"]).pid print "Thanks you will be emailed on completion" Spawn.py script: doVeryLongCalc() emailUser() Basically the problem with this is that the cgi script page in the browser keeps on acting as if its loading until the Spawn.py script is finished executing. Somehow apache "knows" that the spawned process is still running in the background. So I'm basically asking if I can somehow spawn a script that will be completely independent of its parent script? So Apache doesn't know its running and the page finishes loading? Thanks if anyone can help... -- http://mail.python.org/mailman/listinfo/python-list

It is worth noting that other os.system calls in the script get excecuted fine. -- http://mail.python.org/mailman/listinfo/python-list

I am running apache on windows by the way. I think there may be issues with unbuffered output on windows... -- http://mail.python.org/mailman/listinfo/python-list
Re: "Dynamic" website content
To be honest that doesn't seem to work. Also it seems that only Mozilla based browsers support server push. Maybe it is something to do with how Apache is configured? Or is Python buffering the output? Is there a line of code to make python unbeffered? -- http://mail.python.org/mailman/listinfo/python-list
User login system
Can anyone recommend an open source user login system already written in Python that I could use with my site? Simplicity is the most important factor, but the ability to track users using cookies would be helpful. Hopefully somebody knows one? -- http://mail.python.org/mailman/listinfo/python-list

Flushing to stdout doesn't seem to work anyway. Honestly have no idea how you'd implement it in Javascript so might have an ask on one of their forums... -- http://mail.python.org/mailman/listinfo/python-list
Concatinating PDF files
I am converting TIFF images of patents to PDF files. Each patent comes in about 20 seperate TIFF images and I want to put them all in the one PDF file. Is there a way to do this? Using the Image library I think you can only convert individual TIFF images to PDF? Maybe there is a way of concatinating these files or maybe there is a way to create the PDF from the TIFFs in the first place? -- http://mail.python.org/mailman/listinfo/python-list
Re: "Dynamic" website content
To give you a better explaination of what I want, you could visit www.pat2pdf.org. Type in 123456 as the patent number, you see what it does? It tells the user that it is requesting the various TIFF images and then displays the link to the PDF file that it has created. This is exactly what I want to do, so if anyone has any idea how it is done I would be greatful. I'm not asking how to get the TIFF files of create the PDF etc, that is grand, just how it updates the screen with its progress like that... -- http://mail.python.org/mailman/listinfo/python-list
"Dynamic" website content
Basically I have written a cgi script to automatically download TIFF images of patents from the US patent office. What I want is that the user can see what is happening when the images are being downloaded, because it takes a while to download them and there can be anything up to 30 individual files for each image. Is there a way of using Python or any other means, that I could it could print on the webpage: Downloading image 1 Downloading image 2 ... Downloading image X as the individual pictures are being downloaded so the user doesn't think the program is hanging? -- http://mail.python.org/mailman/listinfo/python-list
Re: Uncompressing TIFF files directly in Python
Ya that was the original plan but it didn't support the G4 compression of the tif files! I think the idea of using tiffcp is the best as it runs on both unix and windows which is what i need! -- http://mail.python.org/mailman/listinfo/python-list

Re: Uncompressing TIFF files directly in Python
I mainly just need it to work with windows and assumed that an os call would only work with windows! I've downloaded that free image software and the ctypes program, it seems to be working but I haven't yet worked out how to get it to decompress a G4 TIFF image... If anyone knows it would be of help? -- http://mail.python.org/mailman/listinfo/python-list
Uncompressing TIFF files directly in Python
Hey guys, OK this is a long shot but does anyone know of a way to uncompress tiff files directly in python. I know it can be done with an os call but that'll only work on unix and only if the right software is installed! I need to convert tiff images downloaded from uspto.gov to pdf, these images are compressed using G4, so I dunno if anyone knows of a method of doing this witout the os call! Surely there is a utility out there somewhere? Sophie -- http://mail.python.org/mailman/listinfo/python-list
Re: Converting TIFF files to PDF and/or JPEG
Hmm, does anyone know if there is a way to uncompress Tiff files in python itself without having to make an os call. This is because the script is kind of supposed to run on windows also... Sophie. -- http://mail.python.org/mailman/listinfo/python-list
Converting TIFF files to PDF and/or JPEG
Hey guys, As part of a college project I'm trying to write a script to convert TIFF images downloaded from the US patent office site, www.uspto.gov. The tiff images are encoded using CCITT Group 4 compression and appear to throw an error when i try to save them using the Image library: >>> im.save(outfile, "PDF) It looks like this odd compression format is not supported, or am i wrong? I know its a long shot but would anyone have a different solution? Sophie. -- http://mail.python.org/mailman/listinfo/python-list
CGI question
I was wondering if there was a way to extract everyting in the url after the "?" question mark in one go. I have a search page and a results page, and I want the results page to be able to keep a history of what searches have been performed, but there is always a different number of search terms so there is always a differnet number of parameters, ie. localhost/cgi-bin/results.cgi?TERM1=hello&FIELD1=3&TERM2=python&FIELD2=43&&TERM3=Yallo&FIELD3=21. Is there any easy way of getting the results.cgi program to read this entire URL (or even just the bit after the question mark) or is it a case of writing a comlex bit of code to extract the parameters one by one and create the URL that way? -- http://mail.python.org/mailman/listinfo/python-list
Passing cgi parameters to script...
Is there any way that I can pass cgi parameters to my script locally, before i upload it to the webserver, so that i can debug it. Normally I would pass parameters like this: www.webserver.com/script.cgi?TERM1=hello&FIELD1=TTL&TERM2=goodby&FIELD2=GOVT The problem is that I get errors that do not show up when I run the script locally and I do not have access to the error logs. So is there a way I can pass the form values TERM1, FIELD1 etc to the script without having to upload it to the server? -- http://mail.python.org/mailman/listinfo/python-list
