Replacing repeated consecutive characters in Python

Question

I need to make a function that replaces repeated, consecutive characters with a single character, for example:

 \'hiiii how are you??\' -> \'hi how are you?\'         


        

Answer 1

from collections import OrderedDict

def removeDupWord(word):
   return "".join(OrderedDict.fromkeys(word))

def removeDupSentence(sentence):
    words = sentence.split()
    result = ''
    return ''.join([result + removeDupWord(word) + ' ' for word in words])


sentence = 'hiiii how are you??'
print (removeDupSentence(sentence))

>>> hi how are you?
