如何用括號替換字符串周圍的引號？

Question

雖然大多數 SO 線程都談論從字符串中刪除括號或括號，但我想用括號交換引號，同時保留它們之間的單詞。

我怎么能做到這一點？

# actual
'text \n "rev" INT, \n "count" VARCHAR, etc etc etc'
# expected
'text \n [rev] INT, \n [count] VARCHAR, etc etc etc'

# finds quotes, but unsure how to keep the text and wrap them in brackets
import re
s = 'text \n "rev" INT, \n "count" VARCHAR, etc etc etc'
re.sub('".*?"','[]',s)

Answer 1

您可以使用(...)將引號之間的文本分組，然后在替換時引用它：

import re

s = 'text \n "rev" INT, \n "count" VARCHAR, etc etc etc'

print(re.sub(r'"(.*?)"', r'[\1]', s))

# text
#  [rev] INT,
#  [count] VARCHAR, etc etc etc
