在python中从给定文本中挖掘关键字

Question

待挖掘关键字列表：

keywords_list = ['object-oriented programming','information security industry','python','java programmer']

这是一个文本，上面的关键字必须挖掘出来：

text = "***Python*** allows programmers to define their own types using classes and also ***python*** are most often used for ***object-oriented programming*** .***Python*** has also seen extensive use in the ***information security industry***, including in exploit development."

从上面的文本中，我们必须挖掘给定的关键字，这些关键字可能在文本中，也可能不在文本中。此外，我们还必须计算文本中存在的关键字数量。

输出：

mined_words = ['python','object-oriented programming','information security industry']

count = [3,1,1]

Answer 1

count_list = [text.lower().count(kw) for kw in keywords_list]
mined_text = dict(zip(keywords_list, count_list))
output = sorted(mined_text, key = mined_text.get, reverse=True)
count_output = [mined_text.get(out) for out in output]
