我似乎无法得到这的图书馆工作。我得到了我的访问密钥，秘密和准标记。而我下面同样的事情如 README解释，但是我收到（无，无）而不是价格和货币。我不明白我在做什么错。是不是因为我签署了关于amazon.in？

 ＆GT;＆GT;＆GT;从amazon.api进口AmazonAPI
＆GT;＆GT;＆GT;亚马逊= AmazonAPI（AMAZON_ACCESS_KEY，AMAZON_SECRET_KEY，AMAZON_ASSOC_TAG）
＆GT;＆GT;＆GT;产品= amazon.lookup（ITEMID ='B0051QVF7A'）
＆GT;＆GT;＆GT; product.title
点燃，无线网络连接，6电子墨水屏 - 国际航运
＆GT;＆GT;＆GT; product.price_and_currency
（无，无）
 

解决方案

据发生，因为我在这个例子中提到的产品已不再可用，因此它是显示的价格为无

 ＆GT;＆GT;＆GT;从amazon.api进口AmazonAPI
 ＆GT;＆GT;＆GT;亚马逊= AmazonAPI（AMAZON_ACCESS_KEY，AMAZON_SECRET_KEY，AMAZON_ASSOC_TAG）
 ＆GT;＆GT;＆GT;产品= amazon.lookup（ITEMID ='B00EOE0WKQ'）
 ＆GT;＆GT;＆GT; product.title
 亚马逊消防电话，32GB（AT＆amp; T公司）
 ＆GT;＆GT;＆GT; product.price_and_currency
 （199.0，美元）

I can't seem to get this library working. I got my access key, secret and associate tag. And I am following exact same thing as explained in the README, however I am getting (None, None) instead of price and currency. I don't understand what I am doing wrong. Is it because I signed up on amazon.in?

>>> from amazon.api import AmazonAPI
>>> amazon = AmazonAPI(AMAZON_ACCESS_KEY, AMAZON_SECRET_KEY, AMAZON_ASSOC_TAG)
>>> product = amazon.lookup(ItemId='B0051QVF7A')
>>> product.title
'Kindle, Wi-Fi, 6" E Ink Display - for international shipment'
>>> product.price_and_currency
(None, None)

It was happening because the product I mentioned in the example was no longer available hence it was showing price as None

 >>> from amazon.api import AmazonAPI
 >>> amazon = AmazonAPI(AMAZON_ACCESS_KEY, AMAZON_SECRET_KEY, AMAZON_ASSOC_TAG)
 >>> product = amazon.lookup(ItemId='B00EOE0WKQ')
 >>> product.title
 'Amazon Fire Phone, 32GB (AT&T)'
 >>> product.price_and_currency
 (199.0, 'USD')
 >>> product.ean
 '0848719035209'
 >>> product.large_image_url
 'http://ecx.images-amazon.com/images/I/51BrZzpkWrL.jpg'
