Writing list of feature classes with fields to one csv file per feature class?

Question

I have a database with multiple feature classes. Now I extracted a list of feature classes and a list of fields. I figured out how to write the list of feature classes and the corresponding fields to csv. But the csv file gets really long. Instead I would like to write each feature class name with the corresponding field names to a separate csv file. My code looks like this right now:

def csvwriter (csvfile, mylist):
 myfile = open(csvfile,'ab')
 wr = csv.writer(myfile)
 wr.writerow(mylist)
datasets = arcpy.ListDatasets()
for ds in datasets:
 dslist = []
 dslist.append(ds)
 csvwriter (csvfile1,dslist)
 for fc in arcpy.ListFeatureClasses("*","",ds):
 fclist = []
 fclist.append(fc)
 csvwriter(csvfile1,fclist)
 for field in arcpy.ListFields(fc):
 fieldlist = []
 fieldlist.append(field.name)
 csvwriter(csvfile1,fieldlist)

• Erica: You'll need to change the CSV file name to a variable that depends on the feature class, either changing based on an index value (e.g. 1, 2, 3) or based on the feature class name.
• Kat: @Erica Thanks, that gave me a push in the right direction. I got it to work.
• Erica: OK great -- I was just working up a little script to test it myself, but I'll stop now :)

Answer 1

Instead of using the same csvfile1 each time, define a variable that depends on the feature class name. For example:

fcList = arcpy.ListFeatureClasses()
for fc in fcList:
 csvFileName = 'CSV_{}.csv'.format(fc) # or just = fc + '.csv'
 for field in arcpy.ListFields(fc):
 csvwriter(csvFileName,field.name)
