I have a shapefile with polygons and each polygon has an ID number that follows a pattern like this:
SMP_ID 1077-1-1 8-2-2 1281-1-3 304-2-1
In have created a new field and I need to populate it with a truncated version of these IDs, which would look like this:
SYS_ID 1077-1 8-2 1281-1 304-2
This is the code I've been fiddling with most recently, I feel like it's the closest...
def getSysID(SMP_ID): if SMP_ID is None: return None else: SysID = SMP_ID.split('-') + '-' + SMP_ID.split('-') return SysID
I also tried this method:
id_vals = !SMP_ID!.split("-") SYS_ID = id_vals + "-" + id_vals remainder = id_vals
Something isn't working right, though! There are a few IDs from a different source that don't follow this pattern and are just a string of numbers without hyphens, I'm wondering if that could be a part of the problem?
I'm looking for a solution that will ignore the non-hyphenated IDs and nulls, and copy the truncated hyphenated IDs into a new field.
