How to make python and linux shell interaction？

Question

Now，here is an executable program that I run in a shell. But It needs parameter.How can I use python to pass parameter to the program in a shell. I know a tool in unix named 'expect' which can interact with existing software. I want to know if python can do the same thing！ My english is not good~sorry~

Use the subprocess module. Basic example:

>>> import subprocess as sub
>>> sub.call(["ls", "-l"])

Basically you can pass the command and its parameters as a list of strings.

EDIT: Reading again your question I wonder if pexpect is indeed what you want.
