在字典中添加 key/value 时出现不需要的 "int to tuple" 转换

Question

我正在使用 tweepy 抓取推文，我想为我的数据仓库格式化数据。

每次收到推文时都会调用以下方法：

def on_status(self, status):
    statusAsDict= {
        "text": status.text,
        "created_at": status.created_at,
        "language": status.lang,
        "user": {
            "id": status.author.id,
            "name": status.author.name,
            "screen_name": status.author.screen_name,
            "verified": status.author.verified,
            "favourites_count": status.author.favourites_count,
            "followers_count": status.author.followers_count,
            "friends_count": status.author.friends_count
        }
    }

    if status.in_reply_to_status_id != None:
        statusAsDict["in_reply_to_status_id"] = status.in_reply_to_status_id,

    if status.in_reply_to_screen_name != None:
        statusAsDict["in_reply_to_screen_name"] = status.in_reply_to_screen_name,

    if status.coordinates != None:
        statusAsDict["coordinates"] = status.coordinates,

    if hasattr(status, "retweeted_status"):
        statusAsDict["retweet"] = {}
        statusAsDict["retweet"]["id"] = status.retweeted_status.id,
        statusAsDict["retweet"]["user_id"] = status.retweeted_status.author.id,
        statusAsDict["retweet"]["user_screen_name"] = status.retweeted_status.author.screen_name,
        statusAsDict["retweet"]["user_verified"] = status.retweeted_status.author.verified,
        statusAsDict["retweet"]["user_favourites_count"] = status.retweeted_status.author.favourites_count,
        statusAsDict["retweet"]["user_followers_count"] = status.retweeted_status.author.followers_count,
        statusAsDict["retweet"]["user_friends_count"] = status.retweeted_status.author.friends_count,
        statusAsDict["retweet"]["retweet_count"] = status.retweeted_status.retweet_count,
        statusAsDict["retweet"]["text"] = status.retweeted_status.text,

    if status.in_reply_to_status_id != None:
        print type(status.in_reply_to_status_id)
        print type(statusAsDict["in_reply_to_status_id"])
        print statusAsDict

它打印以下语句：

<type 'int'>
<type 'tuple'>
{'language': u'en', 'text': u'@fuckitslrhafi7 @fuckitslrhafi rt this from ff and main acc for 50 https://....', 'created_at': datetime.datetime(2016, 3, 30, 12, 25, 10), 'in_reply_to_status_id': (715149454257442816,), 'in_reply_to_screen_name': (u'fuckitslrhafi7',), 'user': {'favourites_count': 55, 'screen_name': u'JOlNTZOUlS', 'friends_count': 29, 'followers_count': 16, 'verified': False, 'id': 3040734513, 'name': u'accs in bio'}}

应该是

'in_reply_to_status_id': 715149454257442816

没有

'in_reply_to_status_id': (715149454257442816,)

如何避免从 int 到 tuple 的转换？

Answer 1

去掉你分配的那一行的尾随逗号。

statusAsDict["in_reply_to_status_id"] = status.in_reply_to_status_id

逗号定义元组，而不是圆括号，所以 (1) 仍然是一个整数，1, 是一个元组。

Answer 2

这一行：

statusAsDict["in_reply_to_screen_name"] = status.in_reply_to_screen_name,

有一个尾随逗号 (,)，它将 int 转换为 tuple。

Answer 3

你有一个额外的尾随逗号：

    statusAsDict["in_reply_to_status_id"] = status.in_reply_to_status_id,

删除结尾的逗号，它应该可以工作。例如，1, 是一个元组 (1,)，而 1 只是一个 int.

您可能还想尝试使用 vars 函数将 status 转换为 dict，例如

statusAsDict = vars(status)

Answer 4

我会说，删除语句中的逗号：

statusAsDict['in_reply_to_status_id'] = status.in_reply_to_status_id,
