去掉小括号中的内容？

Question

想把每一行中 () 中的带单词的项去掉，例如第一行中红色方框中的内容都要全部去掉，其他行也是一样。
怎么写代码实现？

( (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)

結果:

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