删除单词中的重复字符 [英] Remove repeating characters from words

问题描述

我想知道将"haaaaapppppyyyy"转换为"haappyy"的最佳方法是什么.

I was wondering what is the best way to convert something like "haaaaapppppyyy" to "haappyy".

基本上，在解析语时，人们有时会重复字符以增加重点.

Basically, when parsing slang, people sometimes repeat characters for added emphasis.

我想知道这样做的最好方法是什么?使用set()无效，因为字母的顺序显然很重要.

I was wondering what the best way to do this is? Using set() doesn't work because the order of the letters is obviously important.

有什么想法吗?我正在使用Python + nltk.

Any ideas? I'm using Python + nltk.

推荐答案

可以使用正则表达式完成:

It can be done using regular expressions:

>>> import re
>>> re.sub(r'(.)\1+', r'\1\1', "haaaaapppppyyy")     
'haappyy'

(.)\1+将任何字符(.)后面跟一个或多个相同字符(由于backref \1必须相同)补充两倍字符.

(.)\1+ repleaces any character (.) followed by one or more of the same character (because of the backref \1 it must be the same) by twice the character.
