I'm using arcpy.da.UpdateCursor to update the UnitName field with an element from a list. I largely based my script off of this question.
This executes successfully:
import arcpy
#fields from the feature class table
field = ['Unit', 'UnitName']
#use a cursor to parse the table of the feature class
with arcpy.da.UpdateCursor(fc, field) as cursor:
for row in cursor:
unit = row[0] #get Unit in field list
s = str(unit).split() #split strings in Unit field
print(s) #print list
Here are a few examples of what prints out:
['200']
['STE', '112']
['STE', 'L']
['UNIT', 'A']
['STE', 'B']
['STE', 'A']
['None']
['None']
But, when I put an index number on the print statement I get the IndexError: list index out of range. Funny thing is I don't get the error right away. A bunch of elements are printed before the error occurs. I think it is because of the None elements.
import arcpy
#fields from the feature class table
field = ['Unit', 'UnitName']
#use a cursor to parse the table of the feature class
with arcpy.da.UpdateCursor(fc, field) as cursor:
for row in cursor:
unit = row[1] #get Unit in field list
s = str(unit).split() #split strings in Unit field
print(s[1]) #print element in second position
row[1] = s[1] #create variable for the element
cursor.updateRow(row) #use cursor to update "UnitName" field with element in second position
