如何删除文本句子中的重复字符？

Question

我有一个文本句子列表，有很多单词，如aaaaa，zzzzz，eeer，qqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqq。。。你知道吗

我正在寻找一种方法来删除我的文字句子这些。你知道吗

text = I'm a really good aaaaaa eeeeer jjjjj llll bb

我不知道我可以用什么正则表达式，所以我可以完全删除这些词。有一些边缘案例，比如

1) aaaaae (you will have one another character at the end)
2) brrrrrr (another character at the beginning)

我在寻找这样的输出

text = I'm really good

我就是不知道怎么做。你知道吗

Answer 1

import re 

text = "I'm a really good aaaaaa eeeeer jjjjj llll bb"
out = re.sub(r"\w*(.)\1{3,}\w*", r"", text)
print(out)
>> I'm a really good     bb

因此，这个正则表达式将查找具有3个或更多重复字符的字符串，即使它位于字符串的开头、中间或结尾。你知道吗

类似“bb”的内容可以被r“\s（.）\1{1，}\s”捕获
