How to remove duplicates only if consecutive in a string?
duplicates, python, string
Solution
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')
Problem
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.
