Hello, Sorry for the newbie question. How do I run a program that could block, waiting for user input, using subprocess.Popen? For example,from subprocess import * def foo(): a = Popen(['python'] ...) I want to be able to get input from the user and send input to the subprocess, printing stdout and stderr as data becomes available, then return once the subprocess exits. Is it possible to send to the subprocess keyboard interrupts, EOF, and such? I tried doing stdout=PIPE, stderr=PIPE, stdin=PIPE. I tried using communicate(), but could only call it once; subsequent calls raised "ValueError: I/O operation on closed file." And both a.stdout.read() and a.stderr.read() blocked the program. Any help would be much appreciated.
Use pexpect, which emulates a pseudo-terminal speaking with the subprocess. Diez -- http://mail.python.org/mailman/listinfo/python-list
