How would I remove adjacent duplicate words in a string. For example 'Hey there There' -> 'Hey there'
re.sub with a backreference we can try:
inp = 'Hey there There' output = re.sub(r'(\w+) \1', r'\1', inp, flags=re.IGNORECASE) print(output) # Hey there
The regex pattern used here says to:
(\w+) match and capture a word [ ] followed by a space \1 then followed by the same word (ignoring case)
Then, we just replace with the first adjacent word.
