Python regex : detect a word with duplicated chars
Question: I wonder if i could detect the word '**hey** ' but in this form : '**heeeey**
' How would i do that in python ? I searched many times but i didn't find an
answer.

*I want the program to get it like 'hey' at last, i want it to understand that 'heeey' means 'hey'.


Answer: 
    import re
    p = re.compile(r'(.)\1+')
    test_str = "heeeey"
    subst = r"\1"
    
    result = re.sub(p, subst, test_str)
    

You can do it through `re.sub`.Here we capture any `character` which are
repeated ahead and replace all by `\1` .So all the repetitions will be gone.

See demo.
