The above answer didn't work for me, listTable kept coming back with a blank result. Using ListFiles with a *.dbf wildcard did the trick.
I used filezilla to download a bunch of zipped shapefiles from ftp://ftp2.census.gov/geo/tiger/TIGER2014/PLACEEC/
I uncompressed them into a single directory (C:/Temp) so that all shapefiles were in one folder.
I have 7-zip, so I just selected all the zip files, right click -> 7-zip -> extract here.
import arcpy
arcpy.env.workspace = "C:/Temp"
files = arcpy.ListFiles ( "*.dbf")
arcpy.Merge_management ( files, "C:/Temp/output.dbf" )
I opened the output.dbf in excel, I had all my data together.
