How can I identify sentences that have a space before a dot '.' and remove this space

Given a random text, how can I identify sentences that have a space before a dot ‘.’, and remove this space?

my_text = 'The pressure is already being monitored. We will report the results soon . kind regards.'

my_text = 'The pressure is already being monitored. We will report the results soon. kind regards.'

>Solution :

import re

my_text = 'The pressure is already being monitored. We will report the results soon . kind regards.'

res = re.sub(r'\s+\.', r'.', my_text)
print(res)
