addressed odd python 3 issue where whichdb cannot recognize an ndbm unless that module has been previously imported.  Also removed file_location variable as it wasn't being used afterall
updated string printing to be consistent between python 2 & 3.  Previously, python 3 would print the db key & values as byte code, while python 2 inherently ignores this when printing.  Now the stdout is the same in both versions.
corrected the import of python 3 modules.  Updated print statements to function form to work correctly with python 2 & 3.  Also decoded the subprocess output into unicode string for splicing and processing of keys
