Hi,
I have a list of sentences and a list of words. Every full word that appears within sentence shall be extended by <WORD> i.e. "I
drink in the house." Would become "I <drink> in the <house>." (and not "I <d<rink> in the
<house>.")I have attempted it like this:
for sentence in sentences:
for noun in nouns:
if " "+noun+" " in sentence or " "+noun+"?" in sentence or " "+noun+"!" in sentence or
" "+noun+"." in sentence:
sentence = sentence.replace(noun, '<' + noun + '>')
print(sentence)
but what if The word is in the beginning of a sentence and I also don't like
the approach using defined word terminations. Also, is there a way to make it
faster?
It sounds like a regex problem to me:
import re
nouns = ["drink", "house"]
pattern = re.compile(r"\b(" + "|".join(nouns) + r")\b")
for sentence in sentences:
sentence = pattern.sub(r"<\g<0>>", sentence)
print(sentence)
