Re: programming toolbox
hi william, I am slightly more experienced in python than you (2 years to be presise). Before this I handled pritty heavy as in coding and as in usage projects in java. Untill I came into the wonderful and powerful world of free software, I programmed in c++ using borlands c++ compiler and IDE. But having all this experience (I still use c for some system programming), python has hooked me. I am so hooked up to python that I have explored all things that is possible in python to the extent of zope and python cgi. If you find that wxpython is any harder then try java swing. By the way have you looked at pygtk. It is not just rich with widgets from gtk but also has great power and flexibility. And since you know wxpython, learning pygtk would be a snap. But as the saying goes, one shoo does not fit all . Obviously if you are thinking about system programming like writing device drivers etc, you will have to keep c in your programming thinkbox. And I find php much better comfortable and powerfull enough for web server programming/ scripting. I can only say one thing. If vb facinated you on windows then, python is a cross platform vb with power of c in many aspects. although as fellow hackers rightly said on this thread previously, there is no harm learning some languages like java which have long life. Keep away from rubbish like c# and similar .net based language. They are very short lived and lak many powerfull features. Happy hacking. Krishnakant.

I think the answer depends on what your goals are. If you want to be a well-rounded programmer, it's good to experience a number of different languages, so you can see different approaches to different problems. Languages like Python tend to obscure to some degree how things actually work inside the machine, whereas languages like C/C++ encourage that a bit more (though assembler much more so). I think it's also a good idea to have more languages under your belt if you want to be a professional programmer. The more tools you have in your toolbox, the more marketable you are... If you only want to learn to program to solve your own problems, then it doesn't really matter. The only reason to learn additional languages is if you find a case where what you've learned doesn't solve your problem, or the solution is a lot harder than it should be. -- Derek D.

Re: Python Written in C?

That's what I was searching for: Python was written in what other language? Are you a PH.d researcher In the first place why do you want to make an issue of what an x language is compiled in and if that' is what you are researching in, then sorry to say you don't seam to have a mindset needed for researcher. See, my concern was something like: OK, if Python is so hot, then, hopefully someone is writing it in assembly language for each MPU chip out there. Otherwise, if, say, they've written it in C#, then it looks like the REAL, generally useful language to learn is C# and Python is akin to Visual Basic or something: a specialty languagewhereas REAL WORLD programmers who want to be generally useful go and learn C#. First off all c# is absolute rubbish waist of time. if I need to learn it then I better lern java or pythonfor that matter. and by the way what is a real programmer? I never knew that there are robots who program vertually and a real programmer . What do you think I am a spam bot who is writing a vertual program every day? first give me your defination for real programmer. So I was suspecting the Python compiler or interpreter is written in a REAL language like C#. So, Wiki says it's written in C! It's almost as if it were an intentional trick...write your own, new language in an OLD, real world language that is passe. Compile it into executable modules of course, so it is a real, working compiler, alright. But the SOURCE is some old, high level language which no one wants to use anymore! So now you've got a hot new language package and no one can say well, it is written in, the SOURCE code is written in, a REAL language. No, it's not! The source is some outdated language and compiler and no one is going to prefer learning THAT to learning your hot new language! what! no one is using c? I want to know what people use to write device drivers? I am such a fool I really never new that people use c# to create device drivers for hardware and for creating firmware. I admit my stupidity that I never knew that c# is real programming language . and what is your programming language?python is a free and open source programming language and does not belong to one person. I'm not dissing Python, here. Just noting that, if it is written in C, that throws a curve at me in trying to balance the value of learning Python vs. some other major language. My request and strong recommendation to you is don't learn python, because you don't deserve to. I am not saying for dissing you, i know you are real programmer . but you seam to have a typical mindset which the rubbish microsoft has inculcated in many programmers, aa sorry real programmers line you. I don't think there is any point saying vvb kind of some thing is great and python is rubbish. every language has its value and vb is not a language in the first place. python is made with a view that it is usefull for all purposes and it has been so far successful and I don't really care why it is done in c as long as it does the work. happy hacking.

Re: Newbie to python --- why should i learn !
hello, I have programmed co insidentally in all the 3 languages. so out of my experience of 10 + years, I got my personal share of reasons to prefer python over the other 2 namely c++ and java. firstly as every one has already explained, python is easy, fun to learn and can do many things much productively for programmers compared to c++ and java. and c# is no better in that. besides, now a days python has become much much faster in some cases faster than java. compare pygtk vs java swing. python has huge amount of libraries/ modules which are as easy to use as the language itself. the syntax difference mentioned in the first email on this thread makes a huge difference when the code becomes complex and the number of lines increase. so there are a lot of reasons to prefer python over java. for the question what can I do in python easier than other languages is not a question to be answered because it all depends on how one associates the problem space with the language space in which the programmer wishes to express the solution. there will be people who will say java is much better choice for large scale programmes but people like myself will always question that. happy hacking.

I tried reading the python docs but did not understand the concept of delta object and how can I measure the difference in terms of days between two dates. I expect that the days would be integers. secondly the format of my date is actually 16/10/2007, and this is all in varchar field inside a postgresql database. I understand that datetime.datetime.strptime would convert this string 16/10/2007 into a date object which I can then compare with the current date created by datetime.now(). is that right? if yes then please explain me how I can get the delta object to give me results in days. regards, Krishnakant. -- http://mail.python.org/mailman/listinfo/python-list

I have not found any such function. if I have looked (or over looked ) in the wrong places I am really sorry. secondly I also want to know the way in which I can convert a given string to a date object. for example if I have a string 29/09/2005, I know it is a valid date although it is in a string form. now I want to convert the above string into a real date object. how can I cast it this way? regards, Krishnakant. -- http://mail.python.org/mailman/listinfo/python-list

problem with quoted strings while inserting into varchar field of database.
hello, I finally got some code to push a pickled list into a database table. but now the problem is technically complex although possible to solve. the problem is that I can nicely pickle and store lists in a blob field with the help of dumps() for picklling into a string and then passing the string to the blob. I am also able to get back the string safely and do a loads() to unpickle the object. but this only works when list contains numbers. if there is a list such als lst = [a,b,c] then after a dumpls I get a pickled object into a string but when I try to insert this into the blob field it refuses to get into the table. there is an sql syntax error. I further discovered that the string variable that contains the pickled object contains a lot of single quots ' and this is what is probably preventing the sql insert from succedding. can some one suggest how to work around this problem? regards, Krishnakant. -- http://mail.python.org/mailman/listinfo/python-list

I created a package in which there were 4 modules and one __init__.py file I created the entire project in eclipse (pydev). it works fine there with the ide. but now when I try running the code without eclipse, that is when I run the individual .py file from a command promt it gives me error. for example I have mainwindow.py, customer.py, stock.py and of course __init__p.py in my package the app is in wxpython which is not important in the context of this problem. never the less I go in the directory called pbcf which is the name of my package there I have all the above mentioned files and the mainwindow.py file is the one I run for testing all the menus. but here the moment I run the file, it starts giving me an error saying pbcf is not a module. I find that the same code runs without any problem in eclipse. in mainwindow.py I have from pbcf import * and in __init__.py I have of course included MySQLdb and wx and in __init__.py I have a connection object called CONCSS. now when I have all the imports in mainwindow, it does work in eclipse but does not on a normal command prompt. why is this? regards.

So, your package must be installed in any directory listed in sys.path, for python to be able to actually find it; perhaps in site-packages. can I have package in a folder and then a main.py in the same folder but out side the package? Also, if you try to execute a module inside your package, it does not even *know* that it lives inside a package. but all this is working in eclipse with pydev. and I looked in the console but there were no errors. -- http://mail.python.org/mailman/listinfo/python-list
Re: confused on python rpc with apache, is it possible?
Use mod_python with some xmlrpc handler. There is more than one around. Google for them. That way you can keep Apache for both Python and PHP. I am confused. I have some documents on xml-rpc but none of them mentioned apache. Krishnakant. -- http://mail.python.org/mailman/listinfo/python-list

python packages and __name__ query.
hello all, I had previously mentioned my doubt and confusion about having a main() to be an entry point in my python based software. I am still having a particular doubt. I use cx freze for creating a python executable. my software is essentially a package containing a few modules and one file where I created the main() function. if needed and suggested by experts I may as well put it in my __init__.py file of the package. coming back to the point. where do I put the following code if __name__ == __main__: main() I have 5 modules in my package each doing a specific task. and a file that contains the main() function. the 5 modules and the exec.py file all are in the same package. if it is a wrong practice please correct me. so plese clear my doubt given the above situation.

how to mimik a main() function to start a program with entry point?
hello all. I have one simple query and may be that's to stupid to answer but I am not finding the answer any ways. I have a set of modules in my package and out if which one is my actual starting point to my entire program. say for example I have an entire database application ready and I want a main (as in java or c) to initiate the program and may be bring up a login screen and then pass the control on to the main window. if I am giving raw source code that is easy because I will tell user to run the command ./xyz.py which has that function. but if I freze it into an executable with py2exe for example , how do I solve this problem? thanks.

confused on python rpc with apache, is it possible?
hello all. I will like to know if the following combination is possible. I have looked around on google and did not find any thing productive so bothering the list: sorry. I am developing a distributed application which will have 3 layers namely the thin client written in wxpython, an application layer on a server and a database server of course. database and application server will be on same physical machine. what I want to know is if I can use python as the base for developing the application layer as an rpc server and use apache server to handle http remote procedure requests from the client? if yes then what basic configuration settings I will need? I believe I must first have apache recognise python interpreter and then do some settings in apache so that it knows that what is happening is not a web page request but an xml-rpc application created in python. can some one guide me? thanks Krishnakant. -- http://mail.python.org/mailman/listinfo/python-list

can't find a suitable application server
hello, I have read about zope and found it very good. but right now I am a bit confused about one project I have just procured. it is supposed to be a simple 3 tear application. the front end will be a thin client which we will develop using wxpython. We are using MySQL for the database and I need to find out a suitable application server where I can do just the following. 1. write my business logic which will actually be the workhorse. 2. send data to the thin client in form of either text or lists or tuples as required. I want my thin client just to take the data and recieve the data. 3. an application server that will process data coming from the thing client. this layer will fire the queries etc. 4. send the processed results in the forms mentioned in point number 2 (sorry if I am redundent). I thought zope is too heavy and complex for this task and zope is generally used in places where the data is too dynamic and the system very complex. I am any ways using MySQL for the rdbms which is more than sufficient so no need for a object oriented database like what zope has. can any one suggest me what to do? right now I get an impression that I must create sockets and send and receave data through that socket to the thin client and put the actual business logic on a seperate machine or on the database server what ever. thanking all.

issues with making a package. where do classes link?

I want to know when I make a package, what are the basic things I must generally do in the __init__.py file? and how do I link all the modules in my project with each other? like when I make a compilation unit in java under a package, the first like of that file will read package mypackage. I did not find any such thing in python that can say that this xyz file is in the abc package. if I want to use one module into another in my same package I can't figure how python figures it out?

problem formatting dates from text fields.
hello all. thanks for the help and for pointing me to the proper url for wxpython related issues. I am so happy that I now have a very easy gui library that can do practically every thing with such ease (no flames intended but I was never at so much ease with java swing ). I however have a problem with dates. I am tired searching for some good tutorial that can explain the basic functionality of wx.datetime class and the datetime picker. I want to display the date in dd/mm/ format and allow the user to change the dates. I then will like to take the value (the entire date) and put into a database. now this is my first question. the other problem is even more tough to solve with my given knowledge of wx.datetime and related classes. unfortunately the database given to me has a text field for date and the data is neetly entered. but when I get the data back from that text field I some how want to convert it back to actual date in the same dd/mm/ format and send this as a value to my date time picker. how can I achieve this? thanking all.

I think experts on this list can give better answer, but efficiency and maintainance wise there is nothing like python I believe. the problem here is that I am from India and all indians on this list can correct me if I am wrong, very few people know about python here. infact a vast majority of programmers ask me python? what is that! they don't even know that it is a programming language, let alone using it. but I am amongst the very few who have actually used both java and python. I need some strong evidence to prove to these stupid and java oriented officials that there is some thing better than java called python. can some one provide me some urls or may be share some personal experience on this issue? I saw a couple of blogs and a few success stories on the python web site itself. but the common answer I am getting is y! even java can do this and java is much faster!

evaluating gui modules, any experience on tkinter?
hello all, I seam to have noticed this a bit late but it appears to me that tkinter is being used very widely for gui development on all platform? is that right? since fredric lundh has written a very good introduction to tkinter (was that just an intro?), I have got keen interest to know the following. may be fredric himself might put some light on these points. 1. I seriously don't intend to start a flame war but does tkinter stand up to the standards of heavy gui development? can I have an entire mdi application working fine with tkinter? I know wxpython can do it and I have heard enough about pyqt, but tkinter seams to be very rich in gui objects. 2. as usual I always look out for accessibility when it comes to gui design. will tkinter be useful for blind people? I mean, are gui apps in tkinter accessible on windows? 3. I don't know if I need any thing else as dependencies on my windows machine. I am using python24 and I did not find any thing about installation in the introduction to tkinter. can some one give me the process of installing tkinter and all necessary things? 4. is tkinter absolutely compatible with windows gui? does it call on native api for native look and feel? in that case I think accessibility issue is automatically solved. I am looking out gui library for some serious application development. one is an erp system and the other is a customer relation management system. so I am confused between wxpython pyqt and now tkinter. out of the 3 I only found qt talking extencively about accessibility, but did not find a way to install qt in the first place. I could not compile qt nor did I find any run-time dlls for mingw so that I can use it out of the box. wxpython is the poorest in documentation and tkinter seams to be best at that. please give me some advice. thanking all.

Re: Secure Python
after reading all the mails on this thread, I have the following observations. I am relatively new to python at its development side but very old as far as using python is concerned. firstly, talking about gnu/linux there is no question about security. python, if at all it is non-secure wont harm a linux machine much any ways. secondly with OS like windows, things will be non-secure, no matter what you do. and it will be un stable and un secure no matter what language you use. how far then is python secured or non-secured in its absolute sence? I need to use python for a very mission critical project. may be I will also use zope. so I will like to know how far I can trust python for security in its absolute (platform independent ) sence? I mean running unwanted code at run-time etc. thanks. Krishnakant. -- http://mail.python.org/mailman/listinfo/python-list
how to print pdf with python on a inkjet printer.
hello all. I am developing an ncurses based python application that will require to create pdf reports for printing. I am not using py--qt or wx python. it is a consol based ui application and I need to make a pdf report and also send it to a lazer or ink jet printer. is it possible to do so with python? or is it that I will have to use the wxpython library asuming that there is a print dialog which can open up the list of printers? if wx python and gui is the only way then it is ok but I will like to keep this application on the ncurses side. thanks.

python and accessibility issues.
this question is streight forward, short and sweet. I am developing some applications and being blind myself, expect that including me, all other blind people must be able to use it. so my question is, is wx python complying with Microsoft Active Accessibility or MSAA for short? I will use wx python or any other gui library that is having support for MSAA built in. thanking all. Krishnakant. -- http://mail.python.org/mailman/listinfo/python-list
a newbi problem: can't find complete python curses library
hello, I am a new member to this list. I am Krishnakant from India, Mumbai. I have been coding in python for quite some time and now I am at the intermediate level of programming as far as python is concerned. I am going to develop a accounting software that can work on the console and accessed through ssh from other terminals. I will like to use the curses or ncurses library for the menus and the input forms with add, save, delete, update and cancel buttens. I also need to create drop down menus with a top level menu bar. I read a few articles about python wrapping curses but can't find some thing very comprehencive. my question is, does python possess a complete wrapper to ncurses and its related libraries like menu, panel and form? if yes then where can I find documentation? I read the python documentation and could manage to find out the window object but nothing on menus and panels and forms. thanks and regards. Please help, Krishnakant. -- http://mail.python.org/mailman/listinfo/python-list
