How to catch this specific exception in Python - amazon.api

Question

API I am using: https://pypi.python.org/pypi/python-amazon-simple-product-api

I have this part of my code

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

Exception I got

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

I tried catching it like this

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

But I got

NameError: global name 'SearchException' is not defined

Then I did this in start of my script

from AWS.ECommerceService.NoExactMatches import SearchException

But then I got this error

ImportError: No module named AWS.ECommerceService.NoExactMatches

My question is how do I silently catch this specific SearchException exception?

Try this:

from amazon.api import AmazonAPI, SearchException

After that,

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

should work as expected.

Try the NoExactMatches exception:

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

Also, modern IDEs (at least PyCharm — definitely) allow you to import anything by just typing the name of class/method/exception/constant etc. and press Alt + Enter. It saves a lot of time.
