Check out module "subprocess" which is meant to replace function "popen3":

pr = subprocess.Popen(["command", "-option1", "-option2"], stdin =
subprocess.PIPE, stdout = subprocess.PIPE, stderr = subprocess.PIPE,
bufsize = 0, close_fds = True)

# And then:
line = pr.stdout.readline()
print line
pr.stdin.write("hello to command")
