Actually that was only a quick fix. The real problem was that I forgot to account for the base case in the searchForFile() method (when the array "files" is null). Thanks again though.

THANKS!!!

I think I may be a little confused, I thought I was doing that.

When the method searchForFile() is ran, it prints out that the file is found (if you created it), once this happens the method should terminate but it does not. I don't understand why the method...

I replaced the old line numbers with the actual line of code

I've created my own recursive file search. When the file is found it is printed that it is found, but the method searchForFile() does not terminate once the file is found, it continues to iterate and...

Begin:

The <expression>s are evaluated sequentially from left to right, and the value of the last <expression> is returned. This expression type is used to sequence side effects such as input and...

I was wondering if there is something in python similar to the begin expression in Scheme, and if not how would you write something in python to simulate it.

What is it??

How would you write a begin procedure in python that would be analogous to the scheme expression.

How would you write your own begin expression, that would be analogous to the built in procedure in scheme?
