python - 如何使用正则表达式将所有重复的标点符号替换为单个标点符号？

Question

我想更改以单个字符替换文本中所有重复的（2+）标点字符：

text = "-alham sedang bermain-main dan makan-makan???? @@alhamsya"

result = "-alham sedang bermain-main dan makan-makan? @alhamsya"

这是我的代码（和here it is on regex reference tester）：

def duplicate_punctuation(text): 
     pattern_regex = "([?@])\\1+" 
     regex_req = re.sub(pattern_regex, "\\1", text) 
     return regex_req

Answer 1

您的表情似乎运作良好：

import re

regex = r"([?@])\1+"

test_str = "-alham sedang bermain-main dan makan-makan???? @@alhamsya"
subst = "\\1"

result = re.sub(regex, subst, test_str, 0)

if result:
    print (result)
