how to run batch process for vector shapefiles

Question

I am kind of new at this.

I ran a gis operation using python, where by I performed euclidean distance for specific state road, river and towns data and reclassified them showing good and bad areas and it worked.

However when I try to run batch processing for two state fils in the same folder, it runs but no output. any ideas how i can batch process vector files before reclassifying the raster output
