A method of implementing interprocess communication between Python execution child processes

The example in this article describes the way Python executes subprocess to implement interprocess communication. Share to everyone for your reference. The implementation methods are as follows:

a.py:

?

1 2 3 4 5 6 7

Import subprocess, Time Subproc = subprocess. Popen ([' C:python31python.exe ', ' c:/b.py '], stdin=subprocess. PIPE, Shell=true) time.sleep (0.5) print (' Start ') subproc.stdin.write (' Datan ') subproc.communicate (' Datan ') print (' End ')

b.py:

?

1 2 3 4

Import SYS print (' Receive ... ') s = Sys.stdin.readline () print (' Get: ', Len (s), s)

I hope this article will help you with your Python programming.
