如何使用正則表達式匹配首字母縮略詞的完整單詞？

Question

我只想從帶有 ( ) 的首字母縮略詞中獲取完整的單詞。

例如，有一句話“肺癌篩查（LCS）降低NSCLC死亡率”； ->結果我想接受“肺癌篩查”。

我怎樣才能用正則表達式做到這一點？

原始問題：我想刪除重復的大寫字母：“HIV acquired immunodeficiency syndrome are at a specially high risk of cervical cancer” => “acquired immunodeficient syndrome are at a particular high risk of cervical cancer”

Answer 1

假設你想定位 2 個或更多大寫字母，我會在這里使用re.sub ：

inp = "Lung cancer screening (LCS) reduces NSCLC mortality"
output = re.sub(r'\s*(?:\([A-Z]+\)|[A-Z]{2,})\s*', ' ', inp).strip()
print(output)  # Lung cancer screening reduces mortality

Answer 2

import re
s = 'HIV acquired immunodeficiency syndrome are at a particularly high risk of cervical cancer'
print(re.sub(r'([A-Z])', lambda pat:'', s).strip()) # Inline
