我写了这段代码，它需要一个输入字符串来获取类似的单词 并创建这些单词的不同组合，在pandas列中搜索每个组合，并返回找到关键词的行的索引。
我在下面编写了代码并且对我来说效果很好，但它比我想要的慢，随着时间的推移，数据框越来越大，我猜测它只会变慢。
所以我想知道是否有更有效的方法可以遵循，我可以改变哪些线来实现这一目标。使用正则表达式搜索或附加列表。
这是我的数据框

这是我的代码。
def bla_bla(model):
input_string = input()
title = input_course.split()
titles = model.most_similar(title)
title_list = []
for keyword in titles:
titles_list.append(keyword[0])
recommended_keywords = titles_list + title
#This is how recommended key_words will look like
['fullstack',
'ror',
'tulsa',
'shrikrishna',
'vanston',
'devtools',
'develoeprs',
'frontend',
'intermidate',
'nunn',
'web',
'developer']
coursat = []
for duo in range(0, len(recommended_keywords)+1):
for subset in itertools.combinations(recommended_keywords, duo):
if len(subset) > 2 and len(subset)<=3:
coursat.append(subset)
else:
pass
my_list = []
for g in coursat:
y = df[df['key_words'].str.contains(".*"+str(g[0])+".*"+str(g[1])+"|"+".*"+str(g[1])+".*"+str(g[0]))]
if y.title.empty:
pass
else: my_list.append(y.title)
return my_list
这应该是我的功能的输出。
