[Python.NET] Installing Python for .NET with .NET 2.0?

[Brian Lloyd]

Hi Aaron - 

PythonNet tip 'o the day: you can probably just construct the array in
Python as a normal list:

  mylist = [[1, 2], [3, 4], ...]

If you pass that to a method with a signature that takes int[,] then
everything should Just Work so long as the lists and their contents
are actually convertible to the stated type ;)

The syntax you're using below is actually trying instantiate a
bound generic type (Array[int] is equivalent to Array<int> in C#),
so when you say 'Array[int](10)' it is trying to create the bound
generic type and initialize it with 10 (which is not an array),
which is probably not what you intended.

hope this helps,

-Brian
