output buffering

[JD]

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.flush()

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:
