>Solution :

The character you’re trying to split on have special meaning in regular expressions. You’d want to escape them. And maybe add them to a set rather than using |, at which point escaping them is unnecessary. We can also specify the trailing space with \s and match one or more spaces with +.

>>> re.split(r'[?.]\s+', "How are you? I am talking to you")
['How are you', 'I am talking to you']
