Program: bookstore()

[muza]

def bookstore(book, price):
    book=title_it_rtn(book_entry)
    return 'Title: ' + book + ' costs $' + price

book_entry = input("enter book name: ")
price_entry = input("price: ")
info=bookstore(book_entry, price_entry)

bookstore(book_entry, price_entry)

is this perfectly ok?
i have one more question. when i create a function with return value, it outputs with single quotes example:

Output:
'my output'

. why this happens. can i remove this so it looks like

Output:
my output

?
