I can not figure out the format specifications, but the following function might be a good starting point:

def lst_to_file(lst, filename, fmt='%08d'):
        '''
        lst: list of arrays to write
        filename: output file name
        fmt: The format of  single item
        '''
	str_lst = []
	for l in lst:
		format = len(l)*fmt + '\n'
		str_lst.append(format % tuple(l))
	open(filename, 'w').write(''.join(str_lst))

Hi Nadav,

Thank you very much. My next question;

How can I save lines_list to a file with the following
so called small field format (NASTRAN). Each row consists
of ten fields of eight characters each.
Field 1 should be empty in my application.
Field 10 is used only for optional continuation 
information when applicable.

12345678123456781234567812345678123456781234567812345678123456781234567812345678
xxxxxxxxyyyyyyyyzzzzzzzz........
  

Cheers,
               Nils
