Tweepy是应该使用pip安装的库之一。现在，为了授权我们的应用代表我们访问Twitter，我们需要使用OAuth接口。Tweepy提供了方便的Cursor接口来迭代不同类型的对象。Twitter允许最多提取3200条推文。

这些都是在收到用户推文之前必须使用的先决条件。

import tweepy

# Fill the X's with the credentials obtained by 
# following the above mentioned procedure.
consumer_key = "XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX"
consumer_secret = "XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX"
access_key = "XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX"
access_secret = "XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX"

# Function to extract tweets
def get_tweets(username):

# Authorization to consumer key and consumer secret
auth = tweepy.OAuthHandler(consumer_key, consumer_secret)

# Access to user's access key and access secret
auth.set_access_token(access_key, access_secret)

# Calling api
api = tweepy.API(auth)
