facing issue when using dictionary in my code

[sanrajbhar]

I want read n update existing metadata replacing some value from external csv file based on fc name as common id between Featureclasses and csv file(3 columns). but whenever I use dict in my code. it is throwing error

import arcpy_metadata as md
import datetime
import arcpy
import os

workspace ='C:\xxx\AssetID_to_Shapefile_Script_Output_V1'

csvpath=r"C:\xxx\test_metadata\test\meta_batch14.csv"


d = {}
with open(csvpath) as f:
    for line in f:
        (key, AccesWidth,drwgNo) = line.split(',')
        d[(key)] = AccesWidth  #EaseWidth
print d




walk = arcpy.da.Walk(workspace, datatype="FeatureClass")
for dirpath, dirnames, filenames in walk:
    for filename in filenames:
        fc=(os.path.join(dirpath, filename))

        
        metadata = md.MetadataEditor(fc)
        print (fun_csvtodict(csvpath))
        fcname=filename[:-4]

        print fcname+'\n' +'\t'+ metadata.abstract



metadata.finish()  
print "~~~~~~~~~~~~~~~~~~~~~~~Finished~~~~~~~~~~~~~~~~~"

NameError: name 'metadata' is not defined

You call metadata.finish() outside the for loop.
You have to call it for each MetadataEditor instance inside the inner loop.

You might get this error b/c no MetadataEditor instance was ever created? Check if your walk function actually finds any FeatureClasses
