Python interacting with Java Script webpage?

[William Dandreta]

I would like to write a Python program that will be able to connect to a
webpage that runs a Java Script, post data to the form displayed, and save
the data retrieved to a file.

I have been looking for a book, tutorial, or any docs that will take me from
not having a clue as to how to do it to being able to write the program.

I read some of the info in the Python refs about the http built in classes
but I did not fully understand it and there really was not enough info there
to get me started.

Any suggestions would be appreciated.
