How to handle Azure Python Function exception handling?

问题

I'm new to Python exception handling. How do I correctly try the following, except if .get_entity fails, but pass if Status 200?

Here is where I'm at:

• Its not correct though. Hoping you could elaborate with an example.

from azure.cosmosdb.table.tableservice import TableService
from azure.cosmosdb.table.models import Entity
from azure.common import AzureMissingResourceHttpError

def get_table_row(TableName, PartitionKey, RowKey):
    try:
        table_lookup = table_service.get_entity(TableName, PartitionKey, RowKey)
    except AzureMissingResourceHttpError as e:
        logging.error(f'#### Status Code: {e.status_code} ####')
    finally:
        if e.status_code == 200:
            return table_lookup
        else:
            logging.error(f'#### Status Code: {e.status_code} ####')

data = get_table_row(TableName, PartitionKey, RowKey)

You can change your code like below:

def get_table_row(TableName, PartitionKey, RowKey):
    try:
        table_lookup = table_service.get_entity(TableName, PartitionKey, RowKey)
    except AzureMissingResourceHttpError as e:
        if e.status_code == 200:
            return table_lookup
        else:
            logging.error(f'#### Status Code: {e.status_code} ####')
            return "whatever you want"
    else:
        return table_lookup
