麻烦分析MWS Boto响应

Question

我在Python中使用Boto连接到亚马逊MWS。我已经成功地使用他们的脚本进行连接，但由于我没有完全理解文档，因此在解析响应时遇到了问题，并且在互联网上几乎没有任何示例。我是Python的新手。

这是我如何得到MWS我的回应：

mws = MWSConnection(accessKeyId,secretKey,Merchant=merchantId) 
response = mws.list_matching_products(MarketplaceId=marketplaceId,Query="Beanie Babies") 

的第一款产品给出了这样的回应：

products = response.ListMatchingProductsResult.Products.Product 
print(products[0]) 
>>>Product{}(Identifiers: ^Identifiers^{}(MarketplaceASIN: ^MarketplaceASIN^{}(MarketplaceId: 'ATVPDKIKX0DER', ASIN: 'B000JK67MQ'), SKUIdentifier: None), Offers: None, CompetitivePricing: [], AttributeSets: ^AttributeSets^{}(ItemAttributes: [ItemAttributes{'xml:lang': 'en-US'}(Brand: 'Beanie Babies', Studio: 'Beanie Babies - Teddy Bears', ItemDimensions: 4.00inchesx10.00inchesx6.00inchesx0.31pounds, Languages: None, Binding: 'Toy', Genre: 'cute pets', Color: 'purple', MaterialType: [], Feature: ['Ty Beanie Baby', 'Princess Bear', 'Purple with purple bow with white flower', 'Does have the tag'], ManufacturerMaximumAge: 36{'Units': 'months'}, OperatingSystem: [], Artist: [], Director: [], ProductTypeName: 'TOYS_AND_GAMES', Creator: [], Edition: '1997', Model: '4300', SmallImage: Image{}(Height: 75{'Units': 'pixels'}, Width: 75{'Units': 'pixels'}, URL: 'http://ecx.images-amazon.com/images/I/4193jH4e35L._SL75_.jpg'), GemType: [], PackageDimensions: 0.90inchesx7.40inchesx4.50inchesx0.40pounds, PackageQuantity: '1', ListPrice: None, Actor: [], Platform: [], Manufacturer: 'Beanie Babies - Teddy Bears', PartNumber: '4300', ProductGroup: 'Toy', MediaType: [], IsMemorabilia: 'false', Label: 'Beanie Babies - Teddy Bears', ManufacturerMinimumAge: 36{'Units': 'months'}, IsAutographed: 'false', IsAdultProduct: 'false', Author: [], Format: [], Title: 'Ty Beanie Babies - Princess Bear', Publisher: 'Beanie Babies - Teddy Bears')]), LowestOfferListings: None, Relationships: ^Relationships^{}(VariationParent: []), SalesRankings: ^SalesRankings^{}(SalesRank: [SalesRank{}(Rank: '60161', ProductCategoryId: 'toy_display_on_website'), SalesRank{}(Rank: '1197', ProductCategoryId: '251943011'), SalesRank{}(Rank: '1609', ProductCategoryId: '11350120011')])) 

我的问题是试图从ItemAttributes中得到的细节：

Attributes = products[0].AttributeSets.ItemAttributes 
print(Attributes[0]) 
>>>ItemAttributes{'xml:lang': 'en-US'}(Brand: 'Beanie Babies', Studio: 'Beanie Babies - Teddy Bears', ItemDimensions: 4.00inchesx10.00inchesx6.00inchesx0.31pounds, Languages: None, Binding: 'Toy', Genre: 'cute pets', Color: 'purple', MaterialType: [], Feature: ['Ty Beanie Baby', 'Princess Bear', 'Purple with purple bow with white flower', 'Does have the tag'], ManufacturerMaximumAge: 36{'Units': 'months'}, OperatingSystem: [], Artist: [], Director: [], ProductTypeName: 'TOYS_AND_GAMES', Creator: [], Edition: '1997', Model: '4300', SmallImage: Image{}(Height: 75{'Units': 'pixels'}, Width: 75{'Units': 'pixels'}, URL: 'http://ecx.images-amazon.com/images/I/4193jH4e35L._SL75_.jpg'), GemType: [], PackageDimensions: 0.90inchesx7.40inchesx4.50inchesx0.40pounds, PackageQuantity: '1', ListPrice: None, Actor: [], Platform: [], Manufacturer: 'Beanie Babies - Teddy Bears', PartNumber: '4300', ProductGroup: 'Toy', MediaType: [], IsMemorabilia: 'false', Label: 'Beanie Babies - Teddy Bears', ManufacturerMinimumAge: 36{'Units': 'months'}, IsAutographed: 'false', IsAdultProduct: 'false', Author: [], Format: [], Title: 'Ty Beanie Babies - Princess Bear', Publisher: 'Beanie Babies - Teddy Bears') 

在这一点上，我相信它是一个字典对象。

print(Attributes[0].values()) 
>>>dict_values(['en-US']) 

由于我是新来这个语言，我无法弄清楚如何获取位于（），如品牌，工作室等

博托有内建的所有信息功能，如响应和ResponseFactory，但当我继续打墙尝试获取品牌等信息时，我再次丢失。

再次感谢您给予的任何帮助。

Answer 1

如果你想“了解详细内容”为输出，你可以尝试Python's Data pretty printer：

的pprint模块提供了能力“漂亮打印”任意 Python数据结构.. 。

它的输出是非常多的可配置的，你可以去结构的任意深度，与depth=...。

如果你想使用其他地方， 我会建议一些事情“细节获得”：

1. 尽量不要与[0]索引，你可能会失去存储在别处的信息在Attributes。
2. 用How do I get list of methods in a Python class?或Finding what methods an object has检查可用的方法。
3. 检查类型与What's the canonical way to check for type in python?。

通过Attributes获得的信息，您应该能够提取存储在其中的任何信息。
