HFSS - importing python modules

So I have been writing a script in python to export data tables, manipulate them in a csv file and import them back into HFSS. The problem I am having is that python scripts run from HFSS do not seem to allow the import of the csv module. I have a piecewise solution where I have a script to export run from HFSS, another that I run outside of HFSS that does the parsing / file manipulation, then a third that imports the data back into HFSS in the form I would like.

My question is: is there a way to get the python script run from HFSS to import the csv module so that I can simplify the procedure down to a single script run from HFSS
