Yo Tiango,
many thanks for your effort.
But if you say:

I´ll forget about that.

that's what i meant with: "(may i could change "print" to "return")"
But i don´t know how to do this?
May we could return to my example:
def chunk_report(bytes_so_far, chunk_size, total_size):
percent = float(bytes_so_far) / total_size
percent = round(percent*100)
return percent
which is called by the def chunk_read:
while 1:
chunk = response.read(chunk_size)
bytes_so_far += len(chunk)
if not chunk:
break
if report_hook:
report_hook(bytes_so_far, chunk_size, total_size)
How to display the output of chunk_report properly? (or how to update
the ProgressBar with that output?)
Best regards,
Dieter Asman
