因为多次重复使用相同的键，所以您一次又一次地重写字典。您可能需要创建字典列表：

books = []    # Start with an empty list
book = {}     # and an empty dictionary for the current book
with open('file.txt', 'r') as f:
    for line in f:
        if line.strip() == "Book":  # Are we at the start of a new book? Then...
            if book:                # Add the current book (if there is one) to list
                books.append(book)
                book = {}           # Start a new book
        else:
            splitLine = line.strip().split()
            book[splitLine[0]] = " ".join(splitLine[1:])
if book:                            # Add final book to list
    books.append(book)
print (books)
