Use the csv module in the standard library.  Here's some pseudocode to 
help you on your way:

Open array.csv to read
Create a csv.reader for it
Open new file (say, out.csv) to write
Create a csv.writer for it
for each line in the reader:
   write the columns you want through the writer

Without a more detailed description it's difficult to be very helpful. 
Basically you read the information from each input file separately and 
write it to your output file.
