    output buffering


    Hello,

    When reading a large datafile, I want to print a '.' to show the
    progress. This fails, I get the series of '.'s after the data has been
    read. Is there a trick to fix this?

    Thanks

      assuming that you're printing to stdout,

      sys.stdout.flus h()

      should do the trick.

              As Fredrik indicated, you need to flush the output buffer. You might also
              want to check out the progress module available from my Python Bits page:

                      The solutions become better and better.
