This works 100% on Mac OSX 10.3.2... The time.sleeps had to be added to 
make it work consistently.

def set_pass():
    # Function to change root passwd on Mac 10.3 systems
    import pexpect
    import time
    set = r"password"
    child = pexpect.spawn("/usr/bin/passwd")
    child.expect_exact("New password:")
    child.sendline(set)
    time.sleep(0.1)
    child.expect_exact("Retype new password:")
    child.sendline(set)
    time.sleep(0.1)
    child.close()

set_pass()
