# Python3.x Python3 os.pipe() Method [ Python3 OS File/Directory Methods](#) * * * ### Overview The os.pipe() method is used to create a pipe, returning a pair of file descriptors (r, w) for reading and writing respectively. ### Syntax The syntax for the **pipe()** method is as follows: os.pipe() ### Parameters * None ### Return Value Returns a pair of file descriptors. ### Example The following example demonstrates the use of the pipe() method: #!/usr/bin/python3import os, sys print ("The child will write text to a pipe and ")print ("the parent will read the text written by child...")# File descriptors r, w are used for reading, writing r, w = os.pipe() processid = os.fork()if processid: # Parent process # Close file descriptor w os.close(w) r = os.fdopen(r) print ("Parent reading") str = r.read() print ("text =", str) sys.exit(0)else: # Child process os.close(r) w = os.fdopen(w, 'w') print ("Child writing") w.write("Text written by child...") w.close() print ("Child closing") sys.exit(0) Executing the above program outputs the following result: The child will write text to a pipe and the parent will read the text written by child...Parent reading Child writing Child closing text = Text written by child...
