"It's always darkest before dawn."

All you need to do is make sure your string is inside quotation marks.

str = "It's always darkest before dawn."

Exercise 9-b

By using first, second and last characters of the string, create a new string.

You can add strings by using (+) character.

Solution

ans_1 = str[0]+str[1]+str[-1]

Exercise 9-c

Replace the (.) with (!)

Hint 1

You can’t directly change a string, because they’re immutable. But you can use .replace() method and assign a new string to the same variable.
