Question

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.

Answer 1

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?
