Okay, thanks!
listdata4 = data4.tolist()
strdata4 = str(listdata4)
strdata4 = strdata4.replace('[','').replace(']','')
and then
outfile2=open(outfilename2,'w')
for element in strdata4:
outfile2.write(element)
The comma separation and format is okay for this application.
The enumerate function looks handy too, thank you again.
Cheers,
Heather

Error message for that:

Heather,
tolist seems to convert the array to a list. So:
listdata4 = data4.tolist()
I would then expect listdata4 to be a list. Looking at the files, you're
trying to take a list
[1,2,3,4]
and get it into the file as
1,2,3,4
So the way you tried at the beginning could work now, if you convert the
list to a string first:
listdata4 = data4.tolist()
strdata4 = str(listdata4)
strdata4 = strdata4.replace('[', '').replace(']','')
But it might not be obvious to programmers not expecting that method.
You could do a for loop:
for element in listdata4:
outfile2.write(element)
But putting in just the right number of commas is irritating. Still might be
the best way:
for i,element in enumerate(listdata4):
if i:
outfile2.write(', ')
outfile2.write(element)
To explain that code:
for i,element in enumerate([1,2,3,4]):
print i,e
prints out
0 1
1 2
2 3
3 4
And 0 is false, 1-3 are true.
I think there were other solutions in other emails, I just know it's hard to
figure out what's going on at the beginning.
Jeff
Also, I attached the type of file I get (using slightly altered code) if I
don't use NumArray, and I just read in a plain list, it is not the correct
format for GIS to accept.
Thank you,
Heather
