正则表达式：匹配句号和python中的一个单词

Question

I am new to regex. I wish to write a regex which matches a '.' followed by a whitespace followed by a word(which does not contain whitespace.

For example, in the string "The sound of cracking. Splintering. A shape appears, in ice.", the regex should extract ". Splintering" and ". A".

Answer 1

import re
input = 'The sound of cracking. Splintering. A shape appears, in ice.'
print re.findall("(\.\s+[a-zA-Z]+)", input)

Output: ['. Splintering', '. A'] ['. Splintering', '. A']

Answer 2

Try:

(\.\s\w+)

Matches:

. Splintering

. A
