[omaha] This is the message I tried to send/post this morning

[Burch Kealey]

   I am thinking I have to create some sort of iterator to move through
   the first subscript I had tried various forms of list comprehension
   and things like append in my many failed attempts. I was sure that I
   could just say something like
   for each in data:
       field1=[data[1]]
   I assumed that by referencing each I was handling the record number
   (equivalent) and field1 is created as a list of single item lists
   The solution that you proposed is similar-it presumes the record
   number is handled by iterating through rec.  Why this works for [0]
   and not any other value??

       sublist = []
       for rec in thedata:
          sublist.append(rec[1])
       Actually-this does not work-I am getting an index out of range
     error.
       When I change the subscript to 0 as in sublist.append(rec[0]) it
       works,  I get the first item from  each  item in  the list. when
     the
       subscript is anything but 0 I get an error message.
