Hello!

Could anyone please explain me why this code:

for i in range(7):
    html('<script>alert("Text %g");</script>' % i)
    time.sleep(1)

gives no alert messages before cell completely calculated? Is there any way to force immediate output processing?

Another example:

for x in range(10):
    html('$\\rho$')
    time.sleep(1)

This code gives immediate output as latex-commands like:

\rho
\newcommand{\Bold}[1]{\mathbf{#1}}

and after cell calculation is done it shows the correct symbols instead of latex-commands.

To give periodic reports about what my code is doing, I sometimes do something like this:

print('About to start something')
os.system('date')
sys.stdout.flush()
#
# The code that does the thing
#
print('Finished doing something'
os.system('date')
sys.stdout.flush()

The "flush" business makes the output actually happen, rather than getting queued up for later. I think this works in both the command line and the notebook (I mostly use the command line).

Thanks for reply! But the flush method is not something that works here. The problem is in processing output not printing it. See new example posted - there is output, but this is raw output, not processed by jsmath or browser itself.
