Question

lets suppose a search term be xxx car costs and i have a paragraphs this is a xxx brand new car, it costs around $120000

i want insert a <strong> tag around the matching words in paragraphs

What i tried

search = 'xxx car costs'
content = 'this is a xxx brand new car, it costs around $120000'
search_terms = search.split()

    for word in search_terms:
        if word not in content: continue
        print('<strong>{}</strong>'.format(word))

This gave me matching keyterms from paragraphs :: xxx car costs

The desired result : this is a xxx brand new car , it costs $120000

Answer 1

A naive approach using str.replace :

for word in search_terms:
   content = content.replace(word, '<strong>'+word+'</strong>')

Answer 2

How about this instead, it's slightly cleaner imho:

search = 'xxx car costs'
content = 'this is a xxx brand new car, it costs around $120000'
search_terms = search.split()

new_content = content
for word in search_terms:
    new_content = new_content.replace(word, '<strong>%s</strong>' % word)

print new_content
