You need to escape the dots with a backslash, they mean any character. You are also better off using a negative character class instead of .*? as it is doing what you are really asking, 'all/any non dots':

[^.]*

Here is an example of what you are asking for.

import re

m ='. Kansas City has a population of 475378. Local time in Kansas City is CST.'
d = re.sub('\.[^.]*\.', '', m)
print(d)

If you want to keep the periods you can simply do this:

d = re.sub('\.[^.]*\.', '..', m)

http://regex101.com/ is a really good site to play around with your regex to tweak it exactly how you'd like to have it work. Good luck!
