How to remove duplicates only if consecutive in a string? [duplicate]
For a string such as '12233322155552', by removing the duplicates, I can get '1235'.
But what I want to keep is '1232152', only removing the consecutive duplicates.
Solution 1:
import re
# Only repeated numbers
answer = re.sub(r'(\d)\1+', r'\1', '12233322155552')
# Any repeated character
answer = re.sub(r'(.)\1+', r'\1', '12233322155552')
Solution 2:
You can use itertools, here is the one liner
>>> s = '12233322155552'
>>> ''.join(i for i, _ in itertools.groupby(s))
'1232152'
