Python：爲什麼traceback打印？

我有一個功能。該函數在一些更多的線程中開始。我試圖打印自己的錯誤消息。但是，我所做的並不重要，我仍然得到印刷的回溯。我的功能：Python：爲什麼traceback打印？

def getSuggestengineResultForThree(suggestengine, seed, dynamoDBLocation): 
    results[seed][suggestengine] = getsuggestsforsearchengine(seed, suggestengine) 

    for keyword_result in results[seed][suggestengine]: 
     o = 0 
     while True: 
      try: 
       allKeywords.put_item(
        Item={ 
         'keyword': keyword_result 
        } 
       ) 
       break 
      except ProvisionedThroughputExceededException as pe: 
       if (o > 9): 
        addtoerrortable(keyword_result) 
        print('ProvisionedThroughputExceededException 10 times in getSuggestengineResultForThree for allKeywords') 
        break 
       sleep(1) 
       o = o + 1 
       print("ProvisionedThroughputExceededException in getSugestengineResult")

但我爲每一個線程像這樣的輸出：

botocore.exceptions.ClientError: An error occurred (ProvisionedThroughputExceededException) when calling the PutItem operation: The level of configured provisioned throughput for the table was exceeded. Consider increasing your provisioning level with the UpdateTable API

有人可以幫助我，讓我自己打印的，而不是追溯？ :)

有可能ProvisionedThroughputExceededException實際上不是錯誤。試試：

except botocore.exceptions.ClientError as pe:

改爲。

如果這不起作用，請找出發生錯誤的線路並將except語句放在那裏。

這個答案對於你的問題來說有點晚，但這裏是任何人在尋找這個答案。

尼爾回答說boto3拋出的異常是botocore.exceptions.ClientError。但是，您應該檢查'ProvisionedThroughputExceededException'的響應錯誤代碼，因爲ClientError可能是另一個問題。

from botocore.exceptions import ClientError 

except ClientError as e: 
    if e.response['Error']['Code'] != 'ProvisionedThroughputExceededException': 
    raise 
    # do something else with 'e'

我正在使用Python 2.7，它可能會或可能不會有所作爲。我收到異常表明boto3已經在做重試（最多9次），這是從你的異常不同：

發生錯誤（ProvisionedThroughputExceededException）調用PutItem操作時（達到最大重試次數：9）：已超過配置的表的配置吞吐量級別。考慮使用UpdateTable API提高您的配置級別。
