Python || Creating new lines based on user input

I am wondering how you can let a given user input create new lines automatically.
Like for instance:

summary = input("Please write a short summary")

Let the user input for example be:

An age-old vendetta between two powerful families erupts into bloodshed. A group of masked Montagues risk further conflict by gatecrashing a Capulet party. A young lovesick Romeo Montague falls instantly in love with Juliet Capulet, who is due to marry her father's choice, the County Paris.

Now I actually want this to be displayed as:

An age-old vendetta between two powerful families erupts into bloodshed.
A group of masked Montagues risk further conflict by gatecrashing a Capulet party.
A young lovesick Romeo Montague falls instantly in love with Juliet Capulet, who is due to marry her father's choice, the County Paris.

As you can see in the last example, it is creating new lines each time.
I know you can create new lines with /n, but not how to import this into user inputs automatically, I hope you understand with the example given above.

>Solution :

How about this :

print(summary.replace('.','.\n'))

Output:

>An age-old vendetta between two powerful families erupts into bloodshed.
 A group of masked Montagues risk further conflict by gatecrashing a Capulet party.
 A young lovesick Romeo Montague falls instantly in love with Juliet Capulet, who is due to marry her father's choice, the County Paris.
