为什么当我试图创建一个从库中删除书籍的函数时，我会出现错误

Question

我想从books_brary中删除的书的示例(取决于书名(输入((：

"图书"：[｛"图书ID"：｛'01'｝，"图书名称"：{‘复仇者’｝，《图书作者》：｛‘斯坦·李’｝、《图书出版年份》：{1938'｝、"图书类型"：{'1'｝，}，"书名"：{"蜘蛛侠"}，"作者"：｛"李"}，"；图书出版年份"：｛1948’｝；书籍类型"：{'2'}，"；书籍副本"：｛15｝｝]｝

我正在使用的函数：

def delete_book(book_name, books_library):
"""
A function that update the collection of books that in the library, without deleting one.
:param book_name: The name of the book to delete.
:param books_library: A collection of all the books in library
"""
for book in range(len(books_library["Books"])):
if book_name in books_library["Books"][book]["Book's Name"]:
print("Are you sure you want delete this book?: ")
identifier = input()
identifiers = ['y','n']
while identifier not in identifiers:
print("Please answer with y or n")
print("Are you sure you want to delete this book?: ")
identifier = input()
if identifier == 'y':
books_library["Books"][book].pop(book)
return f"{book_name} is deleted from books library"
## Todo : Find a way to delete book by his name (should delete all books details)
else:
print(f"The book {book_name} does not exist!")
if identifier == 'n':
print("Canceling...")
break

我在Main.py中使用的代码：

if identifier == '4':  # choosing to Remove a book
print("Which book would you like to remove?: n")
book_name = input()
delete_book(book_name, books_library)
print("The Book has deleted from library.")

我每次都会得到的错误：

Traceback (most recent call last):
File "d:John bryce - pythonFirstProject-managing book librarymain.py", line 83, in 
<module>
delete_book(book_name, books_library)
File "d:John bryce - pythonFirstProject-managing book libraryLibraryBooks.py", 
line 91, in delete_book
books_library["Books"][book].pop(book)
KeyError: 0

Answer 1

尝试替换：

books_library["Books"][book].pop(book)

签字人：

books_library["Books"].pop(book)

Answer 2

基于此：

{'Books': [{"Book's ID": {'001'}, "Book's Name": {'Avengers'}, "Book's Authors": {'Stan Lee'}, "Book's Published year": {'1938'}, "Book's Type": {'1'}, "Book's Copies": {'10'}}, {"Book's ID": {'002'}, "Book's Name": {'Spider Man'}, "Book's Authors": {'Stan Lee'}, "Book's Published year": {'1948'}, "Book's Type": {'2'}, "Book's Copies": {'15'}}]}

您正在从"Books_brary"字典中选择"Books"。

books_library=>dict

books_library['books']=>列出

books_library[quot；books"][book]=>dict

记住第一行

for book in range(len(books_library["Books"]))

"book"是一个整数，它不作为关键字出现在books_brary[quot；books"][book]下的dict中。

我认为这个词应该是

books_library['Books'].pop(book)
