Export feature classes in geodatabase to CSVs

I am trying to export feature classes within a geodatabase to CSV format using “Export Feature Attribute to ASCII” in ArCGIS. I am getting the following error

Traceback (most recent call last):
  File "c:program files (x86)arcgisdesktop10.2ArcToolboxScriptsExportXYV.py", line 159, in <module>
    export = setupXYV()
  File "c:program files (x86)arcgisdesktop10.2ArcToolboxScriptsExportXYV.py", line 49, in setupXYV
    outFieldNames = outFieldNames)
  File "c:program files (x86)arcgisdesktop10.2ArcToolboxScriptsExportXYV.py", line 129, in exportXYV
    formatValue = LOCALE.format(localeDict[field], value)
  File "C:Python27ArcGIS10.2liblocale.py", line 196, in format
    return _format(percent, value, grouping, monetary, *additional)
  File "C:Python27ArcGIS10.2liblocale.py", line 202, in _format
    formatted = percent % value
TypeError: not all arguments converted during string formatting

Here’s the python script I am using

import arcpy
from arcpy import env
import os, sys
arcpy.CheckOutExtension("spatial")    
arcpy.env.overwriteOutput = True

#Set environment settings
workspace = r'L:SimulationOutputPoolVariables.gdb'


# Set local variables
outWorkspace = r'L:SimulationOutputCreateCSV'

feature_classes = []
for dirpath, dirnames, filenames in arcpy.da.Walk(workspace, datatype = "FeatureClass", type = "Point"):
    for filename in filenames:
        feature_classes.append(os.path.join(dirpath, filename))

#print feature_classes

# Loop through feature_classes list

try:
    for fc in feature_classes:
        field_names =[f.name for f in arcpy.ListFields(fc)]
        print field_names
        #arcpy.ExportXYV_stats(fc, field_names, "COMMA",  )
        name = os.path.basename(fc)



    # Extract only the FC basename
        arcpy.ExportXYv_stats(fc, field_names,"COMMA",name, "ADD_FIELD_NAMES")

except:
    print arcpy.GetMessages()

Could someone explain what is happening here?
