Question

我有这句话需要解析。机敏性如下所示：

I'm sure _I_ shan't be able!  I shall be a great deal too far off to trouble myself

我下面需要的结果是：

I'm sure I shan't be able!  I shall be a great deal too far off to trouble myself

表达会是什么样子？

我正在使用的当前表达式是

r'(?!_)\w+'

但是我得到的结果是：

I'm sure I_ shan't be able!  I shall be a great deal too far off to trouble myself

任何建议，谢谢您！

Answer 1

我想你想要这样的东西。

text = "I'm sure _I_ shan't be able!  I shall be a great deal too far off to trouble myself"

print(text.replace('_',''))
#expected output:
#I'm sure I shan't be able!  I shall be a great deal too far off to trouble myself

Answer 2

您可以使用以下方法删除单词周围的所有下划线：

import re

text = "I'm sure _I_ shan't be able! I shall be a great _deal_ too far off to _trouble_ myself"

result = re.sub(r'(_)(\w+)(_)', r'\2', text)

print(result)  # I'm sure I shan't be able! I shall be a great deal too far off to trouble myself
