Strings for a newbie

[Malcolm Wooden]

I'm trying to get my head around Python but seem to be failing miserably. I 
use RealBasic on a Mac and find it an absolute dream! But Python....UGH!

I want to put a sentence of words into an array, eg "This is a sentence of 
words"

In RB it would be simple:

Dim s as string
Dim a(-1) as string
Dim i as integer

s = "This is a sentence of words"
For i = 1 to CountFields(s," ")
  a.append NthField(s," ",i)
next

That's it an array a() containing the words of the sentence.

Now can I see how this is done in Python? - nope!

UGH!
