如何从 Twitter Search API 创建 Pandas 数据框? [英] How to create pandas dataframe from Twitter Search API?

问题描述

我正在使用 Twitter 搜索 API，它返回一个字典字典.我的目标是从响应字典中的键列表创建一个数据框.

I am working with the Twitter Search API which returns a dictionary of dictionaries. My goal is to create a dataframe from a list of keys in the response dictionary.

此处的 API 响应示例:示例响应

Example of API response here: Example Response

我在 Statuses 字典中有一个键列表

I have a list of keys within the Statuses dictionary

keys = ["created_at", "text", "in_reply_to_screen_name", "source"]

我想遍历 Statuses 字典中返回的每个键值，并将它们放入以键为列的数据框中.

I would like to loop through each key value returned in the Statuses dictionary and put them in a dataframe with the keys as the columns.

目前有代码可以单独遍历单个键并分配给列表，然后附加到数据帧，但想要一种方法一次执行多个键.当前代码如下:

Currently have code to loop through a single key individually and assign to list then append to dataframe but want a way to do more than one key at a time. Current code below:

#w is the word to be queired
w = 'keyword'
#count of tweets to return
count = 1000

#API call
query = twitter.search.tweets(q= w, count = count)

def data_l2 (q, k1, k2):

    data = []

    for results in q[k1]:
        data.append(results[k2])

    return(data)

screen_names = data_l3(query, "statuses", "user", "screen_name")

data = {'screen_names':screen_names,
       'tweets':tweets}
frame=pd.DataFrame(data)
frame

推荐答案

我将分享我在使用 Twitter API 时想到的更通用的解决方案.假设您在一个名为 my_ids 的列表中拥有要获取的推文 ID:

I will share a more generic solution that I came up with, as I was working with the Twitter API. Let's say you have the ID's of tweets that you want to fetch in a list called my_ids :

# Fetch tweets from the twitter API using the following loop:
list_of_tweets = []
# Tweets that can't be found are saved in the list below:
cant_find_tweets_for_those_ids = []
for each_id in my_ids:   
    try:
        list_of_tweets.append(api.get_status(each_id))
    except Exception as e:
        cant_find_tweets_for_those_ids.append(each_id)

然后在这个代码块中，我们隔离了我们下载的每个 tweepy 状态对象的 json 部分，并将它们全部添加到列表中....

Then in this code block we isolate the json part of each tweepy status object that we have downloaded and we add them all into a list....

my_list_of_dicts = []
for each_json_tweet in list_of_tweets:
    my_list_of_dicts.append(each_json_tweet._json)

...然后我们将这个列表写入一个 txt 文件:

...and we write this list into a txt file:

with open('tweet_json.txt', 'w') as file:
        file.write(json.dumps(my_list_of_dicts, indent=4))

现在我们将从 tweet_json.txt 文件创建一个 DataFrame(我已经添加了一些与我正在处理的用例相关的键，但您可以添加您的特定键):

Now we are going to create a DataFrame from the tweet_json.txt file (I have added some keys that were relevant to my use case that I was working on, but you can add your specific keys instead):

my_demo_list = []
with open('tweet_json.txt', encoding='utf-8') as json_file:  
    all_data = json.load(json_file)
    for each_dictionary in all_data:
        tweet_id = each_dictionary['id']
        whole_tweet = each_dictionary['text']
        only_url = whole_tweet[whole_tweet.find('https'):]
        favorite_count = each_dictionary['favorite_count']
        retweet_count = each_dictionary['retweet_count']
        created_at = each_dictionary['created_at']
        whole_source = each_dictionary['source']
        only_device = whole_source[whole_source.find('rel="nofollow">') + 15:-4]
        source = only_device
        retweeted_status = each_dictionary['retweeted_status'] = each_dictionary.get('retweeted_status', 'Original tweet')
        if retweeted_status == 'Original tweet':
            url = only_url
        else:
            retweeted_status = 'This is a retweet'
            url = 'This is a retweet'

        my_demo_list.append({'tweet_id': str(tweet_id),
                             'favorite_count': int(favorite_count),
                             'retweet_count': int(retweet_count),
                             'url': url,
                             'created_at': created_at,
                             'source': source,
                             'retweeted_status': retweeted_status,
                            })
        tweet_json = pd.DataFrame(my_demo_list, columns = ['tweet_id', 'favorite_count', 
                                                       'retweet_count', 'created_at',
                                                       'source', 'retweeted_status', 'url'])
