#
bookList = [Book() for b in range(20)]
#
bookList[0].title = "XYZ"
bookList[0].year = 2001
bookList[0].price = 14.99
bookList[0].outOfPrint = False

#
bookList = []
 
newBook = Book("XYZ", 2001, 14.99, False)
bookList.append(newBook)
 
newBook = Book("ABC", 1976, 13.99, True)
bookList.append(newBook)

Traversing an Array of Records

Method 1 – by index

Python
1
2
3
4
5
for b in range(len(bookList)):
    str = bookList[b].title
    str += "was published in "
    str += booklist[b].year
    print(str)

Method 2 – by object

Python
1
2
3
4
5
for book in bookList:
    str = book.title
    str += "was published in "
    str += book.year
    print(str)
