You need to have round brackets to actually call the close method, i.e.:

Did you mean to have the paths of folders (e.g. 'Lab_2/aforker') in the
same list as the paths of zip-files (e.g. 'Lab_2/aforker/aforker_Lab2.zip')?

I don't know what ArcGIS is but if it runs Python then I'm sure that it can
be done with a stand alone .py file.

You're trying to open the directory as if it were a zipfile. You should
pass in the path to a zipfile not to a folder.
Also you're opening the files in append mode 'a'. I think you really want
read-only mode 'r'.

Remove the folder paths from the list of paths.
