How to use regex to find all overlapping matches

Use a capturing group inside a lookahead. The lookahead captures the text you’re interested in, but the actual match is technically the zero-width substring before the lookahead, so the matches are technically non-overlapping: import re s = “123456789123456789” matches = re.finditer(r'(?=(\d{10}))’,s) results = [int(match.group(1)) for match in matches] # results: # [1234567891, # 2345678912, # … Read more

How to find overlapping matches with a regexp?

findall doesn’t yield overlapping matches by default. This expression does however: >>> re.findall(r'(?=(\w\w))’, ‘hello’) [‘he’, ‘el’, ‘ll’, ‘lo’] Here (?=…) is a lookahead assertion: (?=…) matches if … matches next, but doesn’t consume any of the string. This is called a lookahead assertion. For example, Isaac (?=Asimov) will match ‘Isaac ‘ only if it’s followed … Read more
