Strange errors in Pro's Python window with search cursor

DanDeegan — Sun, 12 Dec 2021 00:38:48 GMT

address_sum = 0
with arcpy.da.SearchCursor('AddressPtsFormatted' ["PLOC_"]) as cursor:
   for r in cursor:
   number = r[0]
   address_sum += number‍‍‍‍‍‍‍‍‍

returns the error:

Traceback (most recent call last):File "<string>", line 1, in <module> TypeError: string indices must be integers‍‍‍‍‍‍‍

The code runs in jupytr notebook

(no, i wasn't adding up every address in my area because I am loopy on Friday afternoon, why would anyone find the sum of addresses)

It looks like you posted a partial Traceback, can you share the whole thing? Does Line 1 in your code snippet line up with Line 1 in the error message? I am guessing not because setting a variable to zero would not generate a TypeError.

also, lines 4 and 5 are not indented properly

I tried to make it look better from what was pasted in from Pro. The code runs fine in a jupytr notebook.

That was what was in the Python window in Pro.

Normally when I used cursors, row[0] is not an issue

and it works in this:

PLOCU_set= set(r[0].replace(" ", "") for r in arcpy.da.SearchCursor(fc, ["PLOCU_"]) if not r[0] is None)‍

fc = "AddressPtsFormatted"
address_sum = 0
with arcpy.da.SearchCursor('AddressPtsFormatted' ["PLOC_"]) as cursor:
   for r in cursor:
       number = r[0]
       address_sum += number
Traceback (most recent call last):
  File "<string>", line 3, in <module>
TypeError: string indices must be integers‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

This is what I ran. I cant edit the first post. And I just learned that it helps to set the language before you past code

At a minimum, you are missing a comma after the first argument in your SearchCursor. Try fixing that first.

You might check the value type which script returns, it looks like the type is string rather than integer.

I cant edit the first post.

Look for the edit button at upper right (you can't edit in a dropdown but you can edit by clicking up there).

Not that it matters that much: new Geonet platform soon!

TypeError: means that you are trying to perform an operation on a value whose type is not compatible with that operation. An Iterable is a collection of elements that can be accessed sequentially . In Python, iterable objects are indexed using numbers . When you try to access an iterable object using a string or a float as the index, an error will be returned as TypeError: string indices must be integers. This means that when you're accessing an iterable object like a string or float value, you must do it using an integer value.
