[英]Regex: Allow a string that contains “foo” but not if that same string also contains “bar”
[英]Python if string contains “foo” do this
我有一个Twitter机器人,它响应包含来自数组t
某些字符串的推文。 我正在尝试编写条件语句,以限制其响应包含来自另一个数组a
字符串的推文。 从理论上讲,它应该工作,但是没有。 机器人会忽略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
如果您使用函数来确定某条推文是否包含特定列表中的单词,那么您的程序将比一堆嵌套的for循环好得多。 我还更改了您的变量名称,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
