intersect two list of files

useful check to ensure that there's zero overlap between training/ test/ val splits:


set(open('testFree.jpgl')) & set(open('trainFree.jpgl'))


if you put into a bash script it should look like this


#!/bin/bash                                                                                                                                                                                                                                 
echo -e "for i in set(open('$1')) & set(open('$2')):print i" |  python
