Answer 1

VBA as in what was implemented as part of Office 2000, 2003 and VB6 have been deprecated in favor of .Net technologies. Unless you are maintaining old code stick to python or maybe even go with IronPython for .Net. If you go IronPython, you may have to write some C#/VB.Net helper classes here and there when working with various COM objects such as ones in Office but otherwise it is supposed to be pretty functional and nice. Just about all of the Python goodness is over in IronPython. If you are just doing some COM scripting take a look at what ActiveState puts out. I've used it in the past to do some COM work. Specifically using Python as an Active Scripting language (classic ASP).

I think the equivalent of lists would be arrays in terms of common usage. Where it is common to use a list in Python you would normally use an array in VB. However, VB arrays are very inflexible compared to Python lists and are more like arrays in C.

' An array with 3 elements
'' The number inside the brackets represents the upper bound index
'' ie. the last index you can access
'' So a(2) means you can access a(0), a(1), and a(2) '

Dim a(2) As String
a(0) = "a"
a(1) = "b"
a(2) = "c"

Dim i As Integer
For i = 0 To UBound(a)
    MsgBox a(i)
Next

Note that arrays in VB cannot be resized if you declare the initial number of elements.

' Declare a "dynamic" array '

Dim a() As Variant

' Set the array size to 3 elements '

ReDim a(2)
a(0) = 1
a(1) = 2

' Set the array size to 2 elements
'' If you dont use Preserve then you will lose
'' the existing data in the array '

ReDim Preserve a(1)

You will also come across various collections in VB. eg. http://devguru.com/technologies/vbscript/14045.asp

Dictionaries in VB can be created like this:

Set cars = CreateObject("Scripting.Dictionary")
cars.Add "a", "Alvis"
cars.Add "b", "Buick"
cars.Add "c", "Cadillac"

"I'm having trouble equating a simple List in Python with something in VBA..."

This isn't the best way to learn the language. In a way, you're giving up large pieces of Python because there isn't something like it in VBA.

If there's nothing like a Python list in VBA, then -- well -- it's something new. And new would be the significant value in parts of Python.

The first parts of the Python Built-in Types may not map well to VBA. That makes learning appear daunting. But limiting yourself to just things that appear in VBA tends to prevent learning.

Probably not exactly what you are looking for but this is a decent VBA site if you have some programming background. It's not a list of this = that but more of a problem/solution

Answer 5

This may sound weird, but since I learned data structures in C++, I had a really hard time figuring out how to create them without pointers. There's something about VB6/VBA that makes them feel unnatural to me. Anyway, I came across this section of MSDN that has several data structure examples written in VBA. I found it useful.

Creating Dynamic Data Structures Using Class Modules

Answer 6

While I'm not a Python programmer, you might be able to run VSTO with Iron Python and Visual Studio. At least that way, you won't have to learn VBA syntax.
