Yeah, I figured something like that. > And do whatever is needed to output the numbers from ``slow`` > unbuffered or line buffered. Hm, "slow" of course is just a little test program I wrote for this purpose. In reality I want to call another program whose behavior I can't influence (well, technically I could because it's open-source, but let's assume it to be a black box for now). If 'slow' or some other program does buffered output, how come I can see its output line-by-line in the shell? robert -- http://mail.python.org/mailman/listinfo/python-list
