OK, so I feel like I've tried just about everything here. What I'm looking to do is to concatenate a iteration value (?) from a search cursor with the object ID of a feature class to create a unique ID field. I want these two values separated by a hyphen '-'. Target field (PLOT_ID) is obviously a string. There is what I've got working so far.
i = 1
ptCur = arcpy.da.SearchCursor (ptFC, fldLst)
for row in ptCur:
[various things happen removed for brevity]
Cluster_Plot = str(i) + '!OBJECTID!'
So it appears to be treating the expression inputs as strings. From here I've tried to get a - in between the two values with no luck....even when converting the OID to a string : 'str(!OBJECTID!)' I just can't get things to escape right i guess. Things I've tried:
Cluster_Plot = str(i) + '-' + '!OBJECTID!'
Here the hyphen apparently is interpreted as an operator:
Cluster_Plot = str(i) + " + '-' + " + '!OBJECTID!'
Cluster_Plot = str(i) + " + '-' + " + 'str(!OBJECTID!)'
I dont get this because you can use the + operator in the field calculator just fine (if you format the field as a string using str)
Could someone please help me out of my misery here?
