"Append" means to put at the end.

"Prepend" means to put at the beginning.


Here is a list: [1, 2, 3, 4]


If we APPEND "foo", we get: [1, 2, 3, 4, foo]


If we PREPEND "foo", we get: [foo, 1, 2, 3, 4]


Does that help?

Which module? We don't know which module you are talking about, which makes it 
hard to give you a specific answer.
