It isn't a stupid question, it is a common error which can normally be overcome by breaking the expression down into parts. FULLNAME = 'A1A' FULLNAME.isdigit() False # ---- not all parts of the string are numbers ''.join(filter(str.isdigit, [FULLNAME])) ''‍‍‍‍‍ # ---- So it returns nothing # ---- fails because you can't convert an empty string to an integer int(''.join(filter(str.isdigit, [FULLNAME]))) ‍‍‍‍‍‍‍‍‍ Take your time, use a couple of steps, there are no rewards for the sweet one-liner FULLNAME = 'A1A' tmp = "".join([i for i in FULLNAME if i.isdigit()]) tmp '1' # ---- the list comprehension splits the parts of the string # ---- now, the check again, if it can be converted to an integer # return it, otherwise a suitable nodata value int(tmp) if tmp.isdigit() else -999 1 # ---- success # ----- Now test with a no-number highway FULLNAME = 'A_one_A' tmp = "".join([i for i in FULLNAME if i.isdigit()]) int(tmp) if tmp.isdigit() else -999 -999‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍ Break things into bits, I do it all the time  ...

My guess?  You defined 'workspace' as a variable it during the python session... maybe before shortening it to 'w'. The name,  'workspace' renames in the python namespace until the session is closed... not the script ends, but python is shutdown. If you used a python IDE, like spyder that stores your history, you can review all your definitions and changes when you need to track down answers to mysteries. Otherwise, The true answer will come in a dream .   ... View more

Shifting isn't normal... I suspected a datum shift of the output, but... could be the ellipse.  See if it can be replicated with other simpler geometric shapes. It could be unique to ellipses since "may" be being defined by the long and short axes and a central point rather than an n-gon of points (can't remember offhand)and any small 'issue' with resolution or something would possibly be compounded. Worth a look.  But I would "Tech Support" for a definitive answer. ... View more

No.  You must have defined 'workspace' earlier on. arcpy.env.workspace = r"C:\Git_Dan\npgeom\Project_npg\npgeom.gdb" workspace Traceback (most recent call last): File "<ipython-input-6-91a042f38ba6>", line 1, in <module> workspace NameError: name 'workspace' is not defined‍‍‍‍‍‍ ... View more

Next...  G:\GIS\OakGrove.gdb\Benzene  .... can you confirm that it actually exists by throwing in a print statement, and, that the symbology layer and the layer that is being symbolized are of the same type.  That last one may be the hard one.  But you said all is good when you do it from within ArcMap.  (I can't help on that since I don't use ArcMap anymoree) ...
