使用 Wikipedia API 和 Python 2.7 从列表中提取特定用户评论

Question

我正在使用维基百科 API - wikitools 包从维基百科中提取一些数据。我得到如下所示格式的输出，现在我想提取时间戳和特定用户对多个页面所做的修订的评论。假设我只想要 TechBot 发表的评论，然后我想我可以做类似的事情：

for revision in res["query"]["pages"]["7940378"]["revisions"]:
    if revision["user"] = "Techbot":
        do.something()

但问题是 ["7940378"] 因为这是一个唯一的页面 ID，每个页面都会更改，我不知道如何获取页面 ID。还有其他方法吗？

[{
"query": {
  "pages": {
    "7940378": {
      "ns": 0, 
      "pageid": 7940378, 
      "revisions": [
        {
          "comment": "robot  Modifying: [[az:T\u00fcrk Tarixi]]", 
          "timestamp": "2009-01-03T19:47:11Z", 
          "user": "TechBot"
        }, 
        {
          "comment": "", 
          "timestamp": "2009-02-14T02:07:49Z", 
          "anon": "", 
          "user": "88.231.237.130"
        }, 
        {
          "comment": "fixing recent deletion by merging it with the next paragraph", 
          "timestamp": "2009-04-03T14:49:27Z", 
          "user": "Soap"
        }, 
        {
          "comment": "robot  Modifying: [[az:T\u00fcrk tarixi]]", 
          "timestamp": "2009-04-09T14:35:19Z", 
          "user": "RibotBOT"
        }, 
        {
          "comment": "Repairing link to disambiguation page - [[Wikipedia:Disambiguation pages with links|You can help!]]", 
          "timestamp": "2009-06-12T23:55:55Z", 
          "user": "J04n"
        }
      ], 
      "title": "History of the Turkic peoples"
    }
  }
}, 
"continue": {
  "rvcontinue": "20090807172715|306635892", 
  "continue": "||"
}, 
"warnings": {
  "main": {
    "*": "Unrecognized parameter: 'user'"
  }
}
}]

Answer 1

而不是使用单个 for 循环。你可以分成两个循环，外循环获取页面，内循环获取修订。

for pageid, pagedetails in res["query"]["pages"].iteritems():
    for revision in pagedetails["revisions"]:
        if revision["user"] == "TechBot":
            do.something()
