In Python you would need to phrase that as follows:
  if  (fields[8] == 'N' or fields[8] == 'P') and (fields[6] == '0'
  or fields[6] == '1'):
or alternatively:
  if  (fields[8] in ['N', 'P']) and (fields[6] in ['0', '1']):

Well, you needn't really check the length - you could directly do this:
fields[3] = (fields[3].replace('.', '') + '000000')[:6]
(of course if there are more than 6 digits originally, they'd get
truncated in this case)
