My assignment is:

Answer 1

Just because I couldn't find this solution here.

You can use 'sent_tokenize' method from nltk.

import nltk
string = "hello. my name is Joe. what is your name?"
sentences = nltk.sent_tokenize(string)
print (' '.join([s.replace(s[0],s[0].capitalize(),1) for s in sentences]) )

And the output

Hello. My name is Joe. What is your name?
