我尝试使用以下 for 循环获取“项目”数据:

  data = json.load(urllib2.urlopen(url)) 
  #print data 
  for item in data['findItemsByKeywordsResponse'][0]['searchResult'][0]['item']: 
    for itemId in item['itemId']: 
      print itemId 

这工作正常，但我不确定如何实际获取我试图在底部显示的所有项目数据。

[ 
{ 
@count: "2", 
item: [ 
{}, 
{} 
] 
} 
], 

请您参考如下方法:

data['findItemsByKeywordsResponse'] 是一个 list，因此您可以使用 the_list[0] 访问其中的项目，依此类推.

list 中没有键，键属于dict。
