Make the first letter of each sentence capital without changing the rest of the sentence in Python

Question

I have a sentence like below:

sent = "It was cold yesterday in Chicago. you are sneezing since morning. come in and take rest."

Now, I need to make the first letter after every period as capital without touching the rest of the sentence. Something like this:

"It was cold yesterday in Chicago. You are sneezing since morning. Come in and take rest."

I tried below code:

'. '.join(list(map(lambda x: x.strip().capitalize(), sent.split('.'))))

But this changes the first word to capital and the rest all will change to lower case, like below:

"It was cold yesterday in chicago. You are sneezing since morning. Come in and take rest."

We can observe that 'Chicago' changes to 'chicago' which I do not want. How can I achieve this?

Try this one:

'. '.join(list(map(lambda x: x[0].capitalize() + x[1:], sent.split('. '))))

Or even better using a generator:

'. '.join(x[0].capitalize() + x[1:] for x in sent.split('. '))
