console output delay

[Dominik Kaspar]

hello, my question concerns the following code fragment:

print "searching for bla bla...",
[long calculation]
print "found", numberofblablas

when this program is running, the "please be patient message" is not
displayed until the long calculation has actually completed.
is there any way to force the first print statement to be shown on the
console?

sys.stdout.flush() ?

Alternatively you may find "python -u" to be of help. Using "python -h"
to learn more.

did you try leaving off the comma on the first line?
