Python in web development
Hello All, I have been using Python as a scripting language for my office tasks. Now I have been thinking of using (and learning as well) for web development. For my tasks, I need to perform some tasks and report on the web. Now I have no experience of web development with Python. So, I want to conform first whether Python is best for web development. Python is my personal choice for my automation works and I want to extend it for web development. REQUIREMENT: I need to develop a html form which would take user input and perform some operations (generate intermediate files) and report result on web. >> Some guys in my organization are using Perl for this purpose and thus I >> could get the setup for free.But I want to learn and use Python as >> substitute for Perl. (PHP could also be an option. I have worked on PHP once >> for handling the form data.) So my questions are:- 1. Can I use Python (I want to use personally :)) over PHP/Perl? 2. If Yes, I want to know the modules that I should learn for achieving my requirement. I searched internet and found Python provides CGI, Django etc. I don't much about Django/CGI, please suggest which module I should learn and use. Thanks Sarbjit -- http://mail.python.org/mailman/listinfo/python-list

I resolved it by creating a soft link to this file in my /usr/lib and /usr/lib64. At that point also my LD_LIBRARY_PATH was having path for python lib but was resolved with soft link only. -- http://mail.python.org/mailman/listinfo/python-list

Yes, I configured the makefile for mod_wsgi as without any error : ./configure --prefix=/opt/lampp/ --with-apxs=/opt/lampp/bin/apxs --with-python=/opt/lampp/python/bin/python2.7 --with-mutex-dir=/opt/lampp/var/run/wsgi -- http://mail.python.org/mailman/listinfo/python-list

Yes, I did tried compiling these from the source code and got some errors. I am using Xaamp for linux and following the below link for configuring python/mod_wsgi :- http://www.apachefriends.org/f/viewtopic.php?f=17&t=42975 When I initially tried to compile mod_wsgi, I was getting errors which got resolved by using development package fro Xammp for linux. (Solution found on google) Now I am getting the following compiling errors:- # mod_wsgi.c:14967: error: expected expression before ')' token mod_wsgi.c:14974: error: expected ';' before 'do' mod_wsgi.c:14979: error: expected ';' before '}' token mod_wsgi.c:14984: error: too many arguments to function 'wsgi_log_python_error' mod_wsgi.c:14989: error: expected expression before 'module' mod_wsgi.c: In function 'wsgi_allow_access': mod_wsgi.c:15003: error: 'PyObject' undeclared (first use

How to install development package on linux?
Sorry for this basic question but I am having problem compiling mod_wsgi on Linux. As per mod_wsgi package site, user must have python development package installed on system. I had installed Python2.7 on my Linux system from source code, using the following configuration few months back :- ./configure –prefix= --enable-shared Make –i install But I am not able to find how to install development package from source code. Can some one please conform if I can install the development package from the same source code (Downloaded from Python Website for Unix) and please share the configuration switch for the same. Thanks, Sarbjit -- http://mail.python.org/mailman/listinfo/python-list
How to print stdout before writing stdin using subprocess module in Python?
I am writing a script in which in the external system command may sometimes
require user input. I am not able to handle that properly. I have tried using
os.popen4 and subprocess module but could not achieve the desired behavior.
Below mentioned example would show this problem using "cp" command. ("cp"
command is used to show this problem, i am calling some different exe which may
similarly prompt for user response in some scenarios). In this example there
are two files present on disk and when user tries to copy file1 to file2, an
conformer message comes up.
proc = subprocess.Popen("cp -i a.txt b.txt", shell=True, stdin=subprocess.PIPE,
stdout=subprocess.PIPE, stderr=subprocess.STDOUT,) stdout_val, stderr_val =
proc.communicate() print stdout_val b.txt?
proc.communicate("y")
Now in this example if i read only stdout/stderr and prints it, later on if i
try to write "y" or "n" based on user's input, i got an error that channel is
closed. Can some one please help me on achieving this behavior in python such
that i can print stdout first, then should take user input and write stdin
later on.

How to configure Tkinter Listbox to disable state keeping selected item highlighted
I am having a problem configuring a listbox widget such that the selection remains highlighted even while it is set (programmatically) to the DISABLED state. Below code shows the problem: from Tkinter import * master = Tk() listbox = Listbox(master) listbox.pack() listbox.insert(END, "Text1") listbox.insert(END, "Text2") listbox.insert(END, "Text3") listbox.selection_set(first=0, last=None) listbox.configure(exportselection=False) listbox.configure(state=DISABLED) Now when I change state to NORMAL, selected item is being highlighted. Is there a way I could disable widget (i.e. No response on mouse clicks) but keep the selected object remain highlighted? Intent: I want to utilise this widget on wizard App that I am creating. I would like this widget to indicate the current page / wizard number which the user selected. Is there any other widget I could use instead of it?
