I have this following line of code for which I'm not quite sure the output would be. I have found out that `sys.path` has the first index as an empty string. I think this means add `path1/path2` to the `sys.path` but not sure why do I need `' '` for? I'm using python 2.7. Thanks!

```
extracting_paths = re.findall('.*path1/path2/.*', ' '.join(sys.path))

```
