Do you mean numerical error codes? Which page on the SQLite website
are you referring to? Certainly the exception contains usable data.
Try something like this:
execresult = con.execute('INSERT INTO MyTable (field_name) VALUES
except Exception as error:
print("Didn't work:", error)
(I didn't create a table, so I get "Didn't work: no such table: MyTable")
