Question

这是输出的片段：

innerHTML

我希望得到一个字典格式的变量pageIdCount，其中键是page_id，值是user_id发生的page_id的计数。因此对于userId 1，它应该看起来像：

           {...,"resultMap":
            {..."SEARCH_RESULTS":
             [{..."resultList":[
              {"userClientId":"1"","preferenceValues":["48","51","94"],"MyDate":"7/26/2017 8:30:00 AM"},
              {"userClientId":"2","preferenceValues":["42","11","84"],"MyDate":"7/26/2017 9:40:00 AM"},
              {"userClientId":"3","preferenceValues":["4","16","24"],"MyDate":"7/26/2017 4:20:00 PM"},
              {"userClientId":"4","preferenceValues":["7","2","94"],"MyDate":"7/27/2017 8:00:00 AM"},
              {"userClientId":"1","preferenceValues":["48","22","94"],"MyDate":"7/27/2017 1:50:00 PM"},
              {"userClientId":"2","preferenceValues":["42","11"],"MyDate":"7/27/2017 2:00:00 PM"},
              {"userClientId":"3","preferenceValues":["4","24"],"MyDate":"7/27/2017 6:15:00 PM"},
              {"userClientId":"4","preferenceValues":"7","MyDate":"7/27/2017 9:30:00 PM"}]
             }]
            }
           }

请注意，当preferenceValues中只有1个变量时，没有括号。还有一个字段＆＃34; preferenceValue＆＃34;无论什么都没有括号，它与＆＃34; preferenceValues＆＃34;相同否则。

这可能吗？

在Python 2.7中，我指定了用户，密码和网址，然后我有以下内容：

{"userClientId":"1","preferenceValues":{48:2, 51:1, 94:2, 22:1}}

非常感谢任何帮助。

Answer 1

your_data # this is your data
final_data = {}
for line in yourdata:
    uid = line["userId"]
    pids = line["PageId"]
    if uid not in final_data :
        final_data[uid] = {}
    for pid in pids :
        pid = int(pid)
        if pid not in final_data[uid]:
            final_data[uid][pid]=0
        final_data[uid][pid] += 1
res = [{"userId":uid,"PageIDCount":pids} for uid,pids in final_data.items()]

我想你是开始的，如果是这样的话，这段代码中最棘手的部分可能就是最后一行，它使用了列表理解。关于它，这里是a good lesson。
