python可以代替vb吗,Python是否像VB一样？

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.

解决方案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!
