Make standalone gui-enabled app for LINUX
Hi I know there are tools like cx_freeze or nuitka for making a linux standalone python app. but i couldn't find a good tutorial about how to making a portable gui-enabled python3 app in linux. by gui-enabled i mean application which use any gui libs like pygobject, qt or wx. I know most of linux distros have python installed(usually version 2) and a package manager to install packages with their dependencies(rpm or deb). but i'm thinking of really portable app with all dependencies included to run easily almost on every linux OSs with no trouble even for new or less experienced linux users. So again how can i make a portable python3 + gui(pygobject, qt, wx) for linux? I found some helpful guide for windows, but what about linux? Thanks. -- https://mail.python.org/mailman/listinfo/python-list

formal math ?
Hi,
I have just discovered python and it seems so easy ans so powerful to
me that it remind me matlab or maple programming language (sorry free
software purists ears).
So I was wondering if there a sort of formal math library, that can do
a thing like:
lib.solve("x+1=0")
-> x=-1
I have checked numarray and I think it can not do this.
Thanks in advance,
Mehdi

Re: formal math ?
Thanks you two. I was just thinking if it was possible. If I really want to do this, maybe the best way is to do an interface to python of an open source project I have just discovered : maxima. So long, -- http://mail.python.org/mailman/listinfo/python-list

poblem regarding opening a html file
Hi I have a GUI application (wxpython) that calls another GUI Application. I m using os.system (cmd) to launch The second GUI, in the second GUI I m trying to open the html file using the os.startfile (filename) function but It takes lots of time to open the html file. If I am running only the second application then 'os.startfile' quickly open the html file. Any one can help me to solve this problem. Thanks.

Multiprocessing takes higher execution time
Hi, I use multiprocessing to compare more then one set of files. For comparison each set of files (i.e. Old file1 Vs New file1) I create a process, Process(target=compare, args=(oldFile, newFile)).start() It takes 61 seconds execution time. When I do the same comparison without implementing multiprocessing, it takes 52 seconds execution time. The parallel processing time should be lesser. I am not able to get advantage of multiprocessing here. Any suggestions can be very helpful. Thanks, Gopal -- http://mail.python.org/mailman/listinfo/python-list

RE: Multiprocessing takes higher execution time
Thanks Nick. It processes 10-15 projects(i.e. 10-15 processes are started) at once. One Zip file size is 2-3 MB. When I used dual core system it reduced the execution time from 61 seconds to 55 seconds.

I had a brief look at the code and your use of multiprocessing looks fine. How many projects are you processing at once? And how many MB of zip files is it? As reading zip files does lots of disk IO I would guess it is disk limited rather than anything else, which explains why doing many at once is actually slower (the disk has to do more seeks). -- Nick Craig-Wood -- http://www.craig-wood.com/nick -- http://mail.python.org/mailman/listinfo/python-list

python server side scripting with apache2
Hi Guys, I want to do server side scripting in python for one of my applications. So after installing apache2, python lib for apache2 (libapache2), and doing some changes in default file in /etc/apache2/sites-available i was able to execute python scripts in /var/www/ directory from client side. but i want to place all of my python scripts in some other directory like /home/username/myserver, so what changes i have to make in configuration files at /etc/apache2/apache2.conf or some other place (like /etc/apache2/sites-available/default), so that my server side scripts placed in this folder (/home/username/myserver) gets executed from client side using some url like http://machine-ip/home/username/myserver/abc.py.
