How to answer to prompts automatically with python fabric?

Question

I want to run a command which prompts me to enter yes/no or y/n or whatever. If I just run the command local(\"my_command\") then it stops and asks me for input

Answer 1

Note: this answer is several years old, and in the mean time fabric has (interestingly similar looking) implementation of this. See the answer by @timothée-jeannin below.

See https://stackoverflow.com/a/10007635/708221

pip install fexpect

from ilogue.fexpect import expect, expecting, run 

prompts = []
prompts += expect('What is your name?','John')
prompts += expect('Are you at stackoverflow?','Yes')

with expecting(prompts):
    run('my_command')

Fexpect adds answering to prompts to fabric with use of pexpect
