Python 如果字符串包含 "foo"则执行此操作

Question

我有一个 Twitter 机器人，它响应包含来自数组 t 的特定字符串的推文。我正在尝试编写一个条件语句来限制它响应包含来自另一个数组 a 的字符串的推文。从理论上讲，它应该可以工作，但事实并非如此。机器人忽略 if/else 语句。我的代码如下:

#I search for tweets to my bot's handle
twt = api.search(q='@samplehandle')

#list of specific strings we want to omit from responses
a = ['java',
     'swift']


#list of specific strings I want to check for in tweets and reply to
t = ['I love code',
     'python rocks',
     'javascript']

for c in twt:
    for b in a:
            if b not in c.text:
                for s in twt:
                    for i in t:
                        if i in s.text:
                            sn = s.user.screen_name
                            m = "@%s This is a lovely tweet" % (sn)
                            s = api.update_status(m, s.id)

            else:
                print "Null"

谢谢

如果您使用一个函数来确定一条推文是否包含特定列表中的单词，那么您的程序将比使用大量嵌套的 for 循环更易于管理。我还更改了您的变量名，因为无法使用 a、b、c、d，

#list of specific strings we want to omit from responses
badWords = ['java', 'swift']

#list of specific strings I want to check for in tweets and reply to
goodWords = ['I love code', 'python rocks', 'javascript']


def does_contain_words(tweet, wordsToCheck):
    for word in wordsToCheck:
        if word in tweet:
            return True
    return False

for currentTweet in twt:
    #if the tweet contains a good word and doesn't contain a bad word
    if does_contain_words(currentTweet.text, goodWords) and not does_contain_words(currentTweet.text, badWords):
        #reply to tweet
