【问题描述】：

def reply_to_tweet():
    print("retrieving and replying to tweets...")
    last_seen_tweet = read_last_seen(FILE_NAME)
    # mentions_timeline() returns a list of 20 most recent mentions
    mentions = api.mentions_timeline(last_seen_tweet, tweet_mode="extended")

    # reversing to read old tweets first
    for mention in reversed(mentions):
        print(str(mention.id) + " - " + mention.full_text)
        last_seen_tweet = mention.id
        store_last_seen(FILE_NAME, last_seen_tweet)
        if "#" in mention.full_text.lower():
            print("found #")

            location = get_location(mention.full_text)
            weather = get_weather(location)

            # responding to tweet mention
            api.update_status("@" + mention.user.screen_name + weather, mention.id)

def get_location(tweet):
    # takes tweet and returns only the substring attached to hashtag
    tweet_location = [i.strip("#") for i in tweet.split() if i.startswith("#")[0]]
    tweet_location += " today weather.com"
    return tweet_location

def get_weather(query):
    for url in search(query, stop=1):
        print("Results is " + url)

    #this code sends a request and reads the webpage enclsed to the request
    request = Request(url, headers="User-Agent": "Mozilla/5.0")

    webpage = urlopen(request).read()
    soup = BeautifulSoup(webpage, "html.parser")

    try:
        title = soup.findAll("span", "today-daypart-title")[0].string 
        phrase = soup.findAll("span", "today-daypart-wxphrase")[0].string
    except IndexError as e:
        forecast = (" could not find the weather, check back later")
        print(e)
    else:
        forecast = (" forecast for " + title + " is " + phrase)
        print(forecast)

    return forecast

while True:
    reply_to_tweet()
    time.sleep(15)

然后我调用 reply_to_tweet()，它搜索并显示推文，但是当它尝试我得到的位置时： TypeError：'bool' 对象不可下标 我对机器人和 api 还很陌生，我正在使用 BeautifulSoup、googlesearch 和 tweepy

【问题讨论】：

能否编辑您的帖子以包含get_weather() 和reply_to_tweet() 的代码？

【参考方案1】：

您似乎正在尝试对布尔函数 startswith() 进行字符串切片，请尝试从 tweet_location = [i.strip("#") for i in tweet.split() if i.startswith("#")[0]] 中删除 [0]。

【讨论】：

感谢您的回答，我尝试了您的建议，但出现了一个新错误“TypeError: quote_from_bytes() expected bytes”

@J_Simm 试试这个。 tweet_location = [i.strip("#") for i in tweet.split() if i.startswith("#")][0]

谢谢，这很烦人，因为它只是那件小事，但是由于某种原因它不会得到天气，它不会拉出错误它只是说“列表索引超出范围” .感谢您的帮助。

有没有想过为什么会出现这个索引错误？

@J_Simm 你到底想通过迭代“tweet_location”来提取什么？
