There's naturally a variant that uses the group name instead of the number. This is another Python extension: ``(?P=name)`` indicates that the contents of the group called *name* should again be matched at the current point. The regular expression for finding doubled words, -``(\b\w+)\s+\1`` can also be written as ``(?P<word>\b\w+)\s+(?P=word)``:: +``\b(\w+)\s+\1\b`` can also be written as ``\b(?P<word>\w+)\s+(?P=word)\b``:: - >>> p = re.compile(r'(?P<word>\b\w+)\s+(?P=word)') + >>> p = re.compile(r'\b(?P<word>\w+)\s+(?P=word)\b') >>> p.search('Paris in the the spring').group() 'the the' |
