Use textlines(file) instead of file.readlines() when it's not possible or
desirable to read the entire file into memory at once.  For example:
  for line in textlines(file):
    ...
is computationally equivalent to
  for line in file.readlines():
    ...
but only reads one line at a time into memory.
