As you may or may not know, Microsoft is discontinuing Visual Basic in favor
of VB.NET and that means I need to find a new easy programming language. I
heard that Python is an interpreted language similar to VB. This means that
it doesn't have all the hard stuff like pointers, classes and templates like
C, C++ and assembly language.
Where I work we use Microsoft Office with a lot of customization using
Visual Basic. I would like to switch to Python to do it since VB is being
discontinued. Would Python meet our requirements? I need to make lots of
GUI applications (message boxes, forms, etc.) and do the underlying business
logic too.
Thanks in advance.

First of all, discontinuing VB doesn't mean you have to stop using it.
I worked on a project which was compiled with Visual C 1.52, for many
years after it was not supported. The project is used by nearly every
engineer at the company where I work.
We are still devleoping the project I work on now in VB6, and have no
reason to bail.
For new projects, it would make sense to look into VB.net or some
alternative.
Python has classes, but not templates. However, you don't have to use
classes in your program, but it will make life easier if you learned
them.
Python's classes are not as complicated as C++, it's a much better
language to learn from.
VB has classes too, and if you haven't used them in your programs, then
there's a good chance you can program that way with Python too, but I
wouldn't make a point of it.
VB has a much better IDE than the IDE's for Python, although Eric3 is
one of the best, and is absolutely free.
VB's ide is it's strongpoint, not the language itsself.
If you need to do Gui's then it is extremely usefull to learn the
basics of classes, your code will be much simpler in the long run.
There are many gui toolkits/frameworks for Python, but the foreunners
are pyQT, wxPython, pyGTK, and TK/Tkinter.
You don't have to worry about pointers though :-)
"Would Python meet our requirements? "
Yes and no. Because Python is a very high-level language and
dynamically typed it is easy to learn. Python doesn't make use of
pointers but you are able to write object-oriented code (as opposed to
just being object-friendly like Visual Basic is). You will find that on
its own you won't be able to do any Office macro scripting although
there are several packages that will give you added functionality like
access to Com+ objects (see win32 modules by Mark Hammond). Now, this
may require more work than using VBA but it *is* doable. The com
portion of the win32 modules can enable one to create even a
macro-language unto itself!
Python is very powerful. There are many 3rd party modules and
frameworks (Zope, CherryPy). Also, there are many GUI toolkits
available for it (wxWindows, GTK, QT, Tk and on and on) and you can
also use it as a wrapper to write and compile to Java bytecode (see
Jython). The problem for you, however, is it may or may *not* meet
every requirement. For that you'll have to find out for yourself. I
suggest downloading Python and giving the Python tutorial a whirl and
then taking a look at other Python-related stuff:
[For programmers:] http://docs.python.org/tut/tut.html
[For non-programmers:] http://honors.montana.edu/~jjc/easytut/easytut/
[Win32 stuff:] http://starship.python.net/crew/mhammond/
[Tk 'Tkinter':] http://www.pythonware.com/library/tkinter/introduction/
[wxPython:] http://www.wxpython.org/
[PyGTK:] http://www.pygtk.org/
Purusing these links will give you a very good idea of whether Python
is right for you. Naturally we'd all like to say 'YES Python is good
for you!' but you have to investigate for yourself.
Good luck!

So far as I know, VB.NET is the next version of Visual Basic,
making use of the "common language runtime" -- which, as I understand,
is M$ speak for a byte-code interpreter, ALL the Visual Studio.NET
languages generate the same byte-code (VC still offers a "non-managed"
native mode for writing real low-level stuff). The core VB language is
essentially the same (some more Object Oriented features, maybe), it is
just the associated system libraries that change.
heard that Python is an interpreted language similar to VB. This means that
it doesn't have all the hard stuff like pointers, classes and templates like
C, C++ and assembly language.
You know of an assembly language that does Object Oriented?
My... The world has been waiting with bated breath for that.
Python is OO... It has classes. Unlike Java, it doesn't force
them down your throat if all you want to do is print "Hello World".
Python doesn't have "begin"/"end" (or "{"/"}") to mark code blocks -- it
relies on indentation. Do you have the discipline to rely on the shape
of your code to control logic flow?
Where I work we use Microsoft Office with a lot of customization using
Visual Basic. I would like to switch to Python to do it since VB is being
Visual Basic, or Visual Basic for Applications? VBA is the
internal language of the Office package -- and I wouldn't be surprised
if the newest version of Office starts incorporating parts of the CLR.
VB is the VBA language with stand-alone additions.
discontinued. Would Python meet our requirements? I need to make lots of
GUI applications (message boxes, forms, etc.) and do the underlying business
logic too.
Python, OORexx, PERL, all can do what you want... So could Ada,
C, C++... The question is, would you /want/ to do it in some of those.
You're not going to get, in most cases, drag&drop GUI designers. You'll
have to get down to the native windows calls (if using the win32
extensions for Python), I don't think MFC has been mapped to Python; or
learn a whole new GUI toolset (Python comes with Tk and the Tkinter
interface to it; there are a half dozen other options, some free, some
$$$)
Of the alternatives, I'd push Python, OORexx (though you may
need to "buy" the "batteries" for access to external/system calls), and
maybe Ada or Java... OTOH, I'll also speak blasphemy and suggest you
really look at some of the publications about converting from VB6/VBA to
VB.NET and decide if that is really as bad as you think it is. Check out
appendix A of "VB.NET Language in a NutShell"... Think of VB.NET as "VB
on Java"; some of the changes give VB similar behavior to Java --
strings are immutable and one does not declare a string size, modifying
a string dynamically generates a new string (which is also what Python
does).

On windows it might make sense to choose wxPython, though I've heard
some good stuff about new versions of pyGTK as well.
People coming from VB background probably also appreciate the ability
to draw the UI in point&click style: http://gazpacho.sicem.biz/ http://wxglade.sourceforge.net/
Unfortunately these seem to still be a tad rough around the edges...

VB is not interpreted. Sure! You can compile it to P-Code if you want
to but most people compile to machine code (like C, C++, Assembler).
You are confusing between static linking in C++ etc and mandatory
dynamic linking with VB runtimes with interpreted languages. VB needs
runtimes but is not interpreted generally.
Python is NOT similar to VB. It is much better as a language. VB is
optimized to what you are doing currently. Python is a more general
purpose language.
This means that
it doesn't have all the hard stuff like pointers, classes and
templates like C, C++ and assembly language.
Python has classes.
C and Assembly do not have classes and templates.
If I remember correctly, VB could have pointers too (Address
function?).

using Visual Basic. I would like to switch to Python to do it since VB is

You will probably find migrating to VB.NET easier than to Python if you
have to do WYSIWYG data bound form design.
VB.NET is quite a nice language (I personally prefer C#). Much nicer
than VB6. Python is better but it may not meet YOUR needs
infrastructure wise.

There is no binary distribution for Eric3 on MS Windows. The OP sounds
like he is an exclusively windows programmer.
While we are on topic, is there no one in the Python open source
community who has a commercial license to Qt for Windows and can make a
binary distribution for Eric3 for MS Windows?

I wouldn't advise you to switch to Python from VB if...
1. the installer must be downloaded from the Net, so must be kept as
small as possible (GUI layers like wxWidgets of PyGTK add several
megabytes to your app)
2. you're used to sophisticated GUI designers like VB or Delphi, and
want something as polished
3. you expect an IDE as rich as those two proprietary tools (including
IntelliSense, intigrated GUI designer, compiler, etc.)
4. your app uses third-party components that are not available to
platforms other than VB (or Delphi)
After checking out the tools currently available, I got to the
conclusion that Python is a very fine tool for text-based apps or
moderately-sophisticated GUI apps like BitTorrent.
For more demanding GUI apps, I would advise you stick to VB until the
..Net framework stabilizes and trickles down to being available on 80%
of hosts, at which point you can safely trade horses (VB.Net does
solve some of the oddities of VB Classic.)
In an ideal world, we'd have open-source development tools as rich as
VB or Delphi, but at this point, I haven't found any that doesn't fall
short on any of the points above (probably because the work involved
is underevaluated, and just not doable without a constant and
sufficient revenue stream.)
Just my opinion,
Joe.

This is more a strategic decision than a technical one.
MS has proven that it uses and forces its developers community to
maximize their own profits and spread of technologies. Personally I dont
want to be forced ("Where do you want me to go today?")
Who guarantees that VB.NET will not have the same tragic kismet that VB6
had?
Open Source is totally different and thats the real difference between
VB and python.
As long as their are users and working code, there will be a community
around an OSS tools project.
This is not true for commercial tools, as perfectly proven by MS with
VB6. Its users are crying and MS is deaf because of strategic MS
considerations. http://news.com.com/Developers+slam+...31.html?tag=nl http://news.com.com/Microsoft+walks+...?tag=nefd.lede
