Newbie Question

[Saint Malo]

I am new to programming, and I've chosen python to start with. I wrote
a simple program that asks several questions and assings each one of
them a variable via raw_input command.  I then combined all the
variables into one like this a = b + c + d.  After this I wrote these
values to a file.  What I want to do now is be able to search through
the file for any data in there.  Is this possible?
