去掉小括號(hào)中的內(nèi)容？

clipboard.png

想把每一行中 () 中的帶單詞的項(xiàng)去掉，例如第一行中紅色方框中的內(nèi)容都要全部去掉，其他行也是一樣。
怎么寫(xiě)代碼實(shí)現(xiàn)？

( (S (CC But) (NP (NP (JJ other) (NNS sources)) (ADJP (RB close) (PP (TO to) (NP (DT the) (NN sale))))) (VP (VP (VBD said) (SBAR (S (NP (NNP Vivendi)) (VP (VBD was) (VP (VBG keeping) (S (NP (DT the) (NN door)) (ADJP (JJ open) (PP (TO to) (NP (JJ further) (NNS bids)))))))))) (CC and) (VP (VBD hoped) (S (VP (TO to) (VP (VB see) (S (NP (NNS bidders)) (ADJP (JJ interested) (PP (IN in) (NP (NP (JJ individual) (NNS assets)) (ADJP (NN team) (NN up.)))))))))))) )
( (S (CC But) (NP (NP (JJ other) (NNS sources)) (ADJP (RB close) (PP (TO to) (NP (DT the) (NN sale))))) (VP (VBD said) (SBAR (S (NP (NNP Vivendi)) (VP (VBD was) (VP (VBG keeping) (S (NP (DT the) (NN door)) (VP (VP (VB open) (PP (IN for) (NP (JJ further) (NNS bids))) (PP (IN in) (NP (DT the) (JJ next) (NN day)))) (CC or) (VP (VB two.)))))))))) )

測(cè)資:

string = '( (S (CC But) (NP (NP (JJ other) (NNS sources)) (ADJP (RB close) (PP (TO to) (NP (DT the) (NN sale))))) (VP (VBD said) (SBAR (S (NP (NNP Vivendi)) (VP (VBD was) (VP (VBG keeping) (S (NP (DT the) (NN door)) (VP (VP (VB open) (PP (IN for) (NP (JJ further) (NNS bids))) (PP (IN in) (NP (DT the) (JJ next) (NN day)))) (CC or) (VP (VB two.)))))))))) )'

代碼:

import re

result = re.sub('\(\w+ \w+\)', '',string)
print(result)

結(jié)果:

'( (S  (NP (NP  ) (ADJP  (PP  (NP  )))) (VP  (SBAR (S (NP ) (VP  (VP  (S (NP  ) (VP (VP  (PP  (NP  )) (PP  (NP   )))  (VP (VB two.)))))))))) )'
