How to add whitespace after string.punctuation in Python?

I want to clean my reviews data. Here's my code :

def processData(data):
    data = data.lower() #casefold    
    data = re.sub('<[^>]*>',' ',data) #remove any html     
    data = re.sub(r'#([^\s]+)', r'\1', data) #Replace #word with word
    remove = string.punctuation
    remove = remove.replace("'", "") # don't remove '
    p = r"[{}]".format(remove) #create the pattern
    data = re.sub(p, "", data)
    data = re.sub('[\s]+', ' ', data) #remove additional whitespaces
    pp = re.compile(r"(.)\1{1,}", re.DOTALL) #pattern for remove repetitions 
    data = pp.sub(r"\1\1", data)
    return data

This code almost work well, but there still a problem. For this sentence "she work in public-service" ,

I got "she work in publicservice".

The problem is there are no whitespace after string punctuation.

I want my sentence to be like this "she work in public service".

Can you help me with my code?
