Python Raise Custom Exception
Invalid syntax error (what's wrong with this code?) up vote 2 down vote favorite I am trying to use finally in the following function, however, Python reports a Syntax error. I'm sure I'm doing something silly, but I can't seem to spot it ... Snippet follows below: # Store ids with key # Returns GUID (used to clear table after words) def storeIdsInTemporaryTable(dbinfo, id_list): conn =
Python Exception Stack Trace
dbinfo['db_connection'] guid = genutils.getGUID() orig_tableinfo = dbinfo['table'] orig_datarows = dbinfo['datarows'] metadata = dbinfo['metadata'] sql = "INSERT INTO temporary_data_key (key) VALUES ({0}) RETURNING id".format(guid) key_id = executeSQLonDbConnection(dbinfo, sql, return_field='id') tableinfo = Table('temporary_data', metadata, autoload=True) datarows = [] for id_value in id_list: datarows.append( { 'key_id': key_id, 'id_value': id_value} ) try: insertToDb(dbinfo) except: guid = None # to indicate an error occured if key_id: conn.execute("DELETE FROM temporary_data_key WHERE key={0}".format(guid) finally: dbinfo['table'] = orig_tableinfo dbinfo['datarows'] = orig_datarows return guid What is causing the syntax error?
