A rough beginning might look something like this:

def find_parameter(config_lines, parameter):
    for line in config_lines:
        if line.find(parameter) >= 0:
            return line.split("=")[1]

It can be used like this:

>>> config = ['foo\n', '$db_host="host";\n', '$db_user="user";\n']
>>> find_parameter(config, "$db_user")
'"user";\n'

See http://python.org/doc/current/lib/string-methods.html for more
information about string methods like find and split.

Peace,
