Question

我正在尝试根据要分割的字符之后的字符分割字符串。例如，

k="I would like to eat you"
specialsplit(k,' ')

会返回

['I ', 'ould ', 'ike ', 'o ', 'at ', 'ou']

和

k="I would like to eat you"
specialsplit(k,'e')

会返回

['I would like', 'to e', 't you']

被分割的字符不会像正常分割一样消失，但是后面的字符会消失。我尝试过

def specialsplit(k,d):
    return [e[1:]+d if c!=0 or c==(len(k)-1) else e[:-1] if c==len(k)-1 else e+d for c,e in enumerate(k.split(d))]

，但是它总是将被分割的字符添加到最后一个元素，因此在第二个示例中，它返回了['I would like', 'to e', 't youe']而不是['I would like', 'to e', 't you']。我该如何解决此代码，或者该如何解决？谢谢！

您可以使用re.split：

import re
def specialsplit(_input, _char):
  return re.split(f'(?<={_char})[\w\W]', _input)

print([specialsplit("I would like to eat you", i) for i in [' ', 'e']])

输出：

[['I ', 'ould ', 'ike ', 'o ', 'at ', 'ou'], ['I would like', 'to e', 't you']]

根据分号后的字符分割字符串-python
