麻煩分析MWS Boto響應

Question

我在Python中使用Boto連接到亞馬遜MWS。我已經成功地使用他們的腳本進行連接，但由於我沒有完全理解文檔，因此在解析響應時遇到了問題，並且在互聯網上幾乎沒有任何示例。我是Python的新手。

這是我如何得到MWS我的迴應：

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

的第一款產品給出了這樣的迴應：

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')])) 

我的問題是試圖從ItemAttributes中得到的細節：

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') 

在這一點上，我相信它是一個字典對象。

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

由於我是新來這個語言，我無法弄清楚如何獲取位於（），如品牌，工作室等

博託有內建的所有信息功能，如響應和ResponseFactory，但當我繼續打牆嘗試獲取品牌等信息時，我再次丟失。

再次感謝您給予的任何幫助。

Answer 1

如果你想「瞭解詳細內容」爲輸出，你可以嘗試Python's Data pretty printer：

的pprint模塊提供了能力「漂亮打印」任意 Python數據結構.. 。

它的輸出是非常多的可配置的，你可以去結構的任意深度，與depth=...。

如果你想使用其他地方， 我會建議一些事情「細節獲得」：

1. 儘量不要與[0]索引，你可能會失去存儲在別處的信息在Attributes。
2. 用How do I get list of methods in a Python class?或Finding what methods an object has檢查可用的方法。
3. 檢查類型與What's the canonical way to check for type in python?。

通過Attributes獲得的信息，您應該能夠提取存儲在其中的任何信息。
