Keep Track Of Number Of Bytes Read

I would like to implement a command line progress bar for one of my programs IN PYTHON which reads text from a file line by line. I can implement the progress scale in one of two

Solution 1:

bytesread = 0whileTrue:
  line = fh.readline()
  if line == '':
    break
  bytesread += len(line)

Or, a little shorter:

bytesread = 0for line in fh:
  bytesread += len(line)

Using os.path.getsize() (or os.stat) is an efficient way of determining the file size.
