Python named pipes on Linux. How to read and write?

Question

linux

OS: CentOS 7
Python: 2.4.
Created a named pipe in Linux, using the OS itself through:

mkfifo

. I'm trying to open it for reading like this:

pipe = open("testpipe","r")

But the program just hangs on this command. Does not crash on an exception, but freezes, interruption on

ctrl+c

works, so, in fact, I complete its work.
What could be the problem and how to deal with it?

Answer 1

Perhaps this is not a problem.
You are working with a named pipe. If you read it, the program does not freeze, but waits for someone to write something to this channel.
