如何将列表中的字符串与文本匹配并执行某些操作

Question

我有关键字列表，让我们在这样的列表中说 6...

keywords = ['python', 'c plus plus', 'java', 'javascript', 'c#', 'assembly']

并有成千上万这样的句子......

 sentence = [

'my first python program was a scraping script',

'i want to learn c plus plus in future',

'i want to learn java in future too',

'i love javascript very much',

'my friend very knowledgeble in c# programming',

'i heard of assembly but never tried yet'

]

我想要做的是从关键字列表中获取一个关键字，让我们说“python”然后搜索所有句子，如果找到则执行某些操作或否则通过。我尝试过一些东西，但如果我添加更多关键字，那么代码会很长。我在 SO 上进行了搜索，但无法获得我想要完成的任务。有没有更好的方法...提前致谢。

这是我尝试过的一些代码

keywords = ['python', 'c plus plus', 'java', 'javascript', 'c#', 'assembly']

sentence = [

'my first python program was a scraping script',

'i want to learn c plus plus in future',

'i want to learn java in future too',

'i love javascript very much',

'my friend very knowledgeble in c# programming',

'i heard of assembly but never tried yet'

]

for i in sentence:

    if 'python' in i:

        lang = 'python'

        begining = i.split('python')[-1]

        ending = i.split('python')[0]

    elif 'c plus plus' in i:

        lang = 'c plus plus'

        begining = i.split('c plus plus')[-1]

        ending = i.split('c plus plus')[0]

    elif 'java' in i:

        lang = 'java'

        begining = i.split('java')[-1]

        ending = i.split('java')[0]

    elif 'javascript' in i:

        lang = 'javascript'

        begining = i.split('javascript')[-1]

        ending = i.split('javascript')[0]

    elif 'c#' in i:

        lang = 'c#'

        begining = i.split('c#')[-1]

        ending = i.split('c#')[0]

    elif 'assembly' in i:

        lang = 'assembly'

        begining = i.split('assembly')[-1]

        ending = i.split('assembly')[0] 

    else:

        pass

    print lang, begining, ending

Answer 1

您可以更有效地进行迭代，如下所示：”for kw in keywords:    for sent in sentences:        if kw in sent:             lang = kw             beginning,ending = sent.split(kw,1) ## Force to only split 1 time

Answer 2

languages = [...]sentences = [...]for sentence in sentences:    for language in languages:        if language in sentence:            ...
