如何在Python-amazon.api中捕获此特定异常

我使用的API：

我有这部分代码

from amazon.api import AmazonAPI
products = self.amazon_api.search_n(1, Keywords=item['upc'], SearchIndex='All')

我得到了一个例外

SearchException: Amazon Search Error: 'AWS.ECommerceService.NoExactMatches', 'We did not find any matches for your request.'

我试着这样抓住它

try:
    products = self.amazon_api.search_n(1, Keywords=item['upc'], SearchIndex='All')
    found_match = True
except SearchException:
    logging.warning("No search result found on Amazon for UPC: %s"%(item['upc']))
    found_match = False

但是我有

NameError: global name 'SearchException' is not defined

然后我在我的剧本开始时就这样做了

from AWS.ECommerceService.NoExactMatches import SearchException

但后来我犯了这个错误

ImportError: No module named AWS.ECommerceService.NoExactMatches

我的问题是如何静默地捕捉这个特定的

SearchException

exception？

试试这个：

from amazon.api import AmazonAPI, SearchException

此后,

try:
    products = self.amazon_api.search_n(1, Keywords=item['upc'], SearchIndex='All')
    found_match = True
except SearchException:
    logging.warning("No search result found on Amazon for UPC: %s"%(item['upc']))
    found_match = False

应该像预期的那样工作

可以找到文档。

尝试

NoExactMatches

异常：

from AWS.EcommerceServiec import NoExactMatches

try:
    products = self.amazon_api.search_n(1, Keywords=item['upc'], 
SearchIndex='All')
    found_match = True
except NoExactMatches:
    logging.warning("No search result found on Amazon for UPC: %s"%(item['upc']))
    found_match = False

此外，现代IDE（至少是PyCharm-明确地）允许您输入任何内容，只需键入类/方法/异常/常量等名称，然后按Alt+Enter。这节省了很多时间。
