python - 删除元音，除非它是单词的开头

Question

我正在尝试删除字符串中出现的元音，除非它们是单词的开头。因此，例如像 “The boy is abt abt wn” 这样的输入应该输出 Th by is abt t wn。这是我目前所拥有的。任何帮助将不胜感激!

def short(s):
vowels = ('a', 'e', 'i', 'o', 'u')
noVowel= s
toLower = s.lower()
for i in toLower.split():
    if i[0] not in vowels:
        noVowel = noVowel.replace(i, '')        
return noVowel

Answer 1

一种方法是使用正则表达式替换前面没有单词边界的元音。此外，如果您的代码应该处理带有各种标点符号的任意文本，您可能需要考虑一些更有趣的测试用例。

import re
s = "The boy is about to win (or draw). Give him a trophy to boost his self-esteem."
rgx = re.compile(r'\B[aeiou]', re.IGNORECASE)
print rgx.sub('', s)  # Th by is abt t wn (or drw). Gv hm a trphy t bst hs slf-estm.
