I have some articles containing match scores like 13-9, 34-12, 22-10 which I want to extract using a regular expression to find the pattern in Python. re.compile(r'[0-9]+-[0-9]')
works but how can I modify to eliminate 1999-06, 2020-01? I tried re.compile(r'[0-9]{1,2}-[0-9]')
but those year values return as 99-06 which is also invalid in my case.
You can match for exact number of digits required with look behind assertions, not to slice log numbers, like below
(?<!\d)\d{2}-\d{1,2}
You can avoid matching in the middle of a number with
r'(?<!\d)[0-9]{1,2}-[0-9]'
The negative lookbehind prohibits matching immediately after another digit.
Perhaps also add
(?!\d)
at the end to impose a similar restriction at the end of the match.
