As Peter said, nothing for now. But you seem very resistant to telling us what exception was raised. Though looking at your code more closely I can see that likely the error is related to the fact that /tmp/mypipe is not an executable program. popen (which is deprecated and replaced by the subprocess module) is for running programs and communicating with them over pipes created by the popen function. So your code is not likely to ever work as it is presently given. Here's the bash equivalent of your code: $ mkfifo /tmp/path $ cat </tmp/path & $ echo hello, world | /tmp/path Bash will say, "bash: /tmp/path: Permission denied" The correct bash line is: $ echo hello, world > /tmp/path popen() (and subprocess) is the equivalent of the first bash command. open() is the equivalent of the second line.
