mkfifo() method in Python is used to create a FIFO (a named pipe) named path with the specified mode. FIFOs are named pipe which can be accessed like other regular files. This method only create FIFO but don’t open it and the created FIFO does exist until they are deleted.To create a FIFO(named pipe) and use it in Python, you can use the os. mkfifo(). But mkfifo fails with File exists exception if file already exists. In order to avoid that, you can put it in a try-except block.Pipe is a Python library that enables you to use pipes in Python. A pipe ( | ) passes the results of one method to another method. I like Pipe because it makes my code look cleaner when applying multiple methods to a Python iterable. Since Pipe only provides a few methods, it is also very easy to learn Pipe.

- Access the named pipe using the appropriate I/O method.
- Communicate through the pipe with another process using file I/O functions: …
- Close the named pipe.
