Class record structure only recording last input

Question

I am trying to create an array Record structure using a class in Python 3. This is my code:

class Books():
    def __init__(self):
        self.title=""
        self.author=""

newbooks=[Books()]*4

for i in range(4):
    newbooks[i].title=input("Input title of the book")
    newbooks[i].author=input("Input author of the book")


print(newbooks[0].title)

However, the final line will always print the final input rather than the first. Every element in my array stores the final input and not the one entered on the correct counter. I'm a little confused as to why; any help?
