Programmatically enter password on prompt within Python?

I need functionality similar to the Unix expect from within a Python script, as an external executable is prompting for password. I am currently doing this:

p = subprocess.Popen("execA",stdout=subprocess.PIPE,stderr=subprocess.STDOUT)

where execA is prompting for password. I'd like to wrap it with "expect" to supply said password.

There seem to be a few alternatives:

Pexpect - Noah Spurrier

Python Expect

What is the best way to do this? If there's a more efficient way to go about it, I'd love to know.

Those kind of programs typically access the tty directly and put it in "raw" mode. So the stdio pipes don't work. You need to spawn the subprocess in a pty. A simple read/write with that might work. Those "expect-like" modules are usually for more complex scenarios.

Of course I prefer this one, but I'm not sure it will work on OSX.

Pexpect is the one I've used in the past to do things like this.

Though depending on the program it might be sufficient to just write to it's stdin?
