我正在尝试解析一个文本文件以在 python 中对其进行一些统计。为此，我想用标记替换一些标点符号。这种标记的一个例子是所有终止句子的标点符号( .!? 变成 <EndS> )。我设法使用正则表达式做到了这一点。现在我正在尝试解析引号。因此，我认为，我需要一种方法来区分开盘价和收盘价。我正在逐行读取输入文件，我不能保证报价会被平衡。
例如:
"Death to the traitors!" cried the exasperated burghers.
"Go along with you," growled the officer, "you always cry the same thing over again. It is very tiresome."
应该变成这样:
[Open] Death to the traitors! [Close] cried the exasperated burghers.
[Open] Go along with you, [Close] growled the officer, [Open] you always cry the same thing over again. It is very tiresome. [Close]
是否可以使用正则表达式来做到这一点？有没有更简单/更好的方法来做到这一点？
请您参考如下方法:
您可以使用sub 方法(模块重新):
import re
def replace_dbquote(render):
return '[OPEN]' + render.group(0).replace('"', '') + '[CLOSE]'
string = '"Death to the traitors!" cried the exasperated burghers. "Go along with you", growled the officer.'
parser = re.sub('"[^"]*"', replace_dbquote, string)
print(parser)
