'Book' object has no attribute 'iloc'

根据提供的引用内容，'Book'对象没有'iloc'属性。这意味着在'Book'对象上无法使用'iloc'方法。通常，'iloc'是用于在pandas库中的DataFrame或Series对象上进行索引和切片操作的方法。如果您想在'Book'对象上使用类似的功能，您可以检查该对象是否具有其他可用的方法或属性来实现您的需求。

AttributeError: list object has no attribute iloc

`iloc` is a method provided by Pandas DataFrame and Series objects to access data using integer-based indexing. It seems that you are using it with a list object which does not have this attribute.

To resolve this error, you should check if you are working with a Pandas DataFrame or Series object when trying to use `iloc`. If you are working with a list object, you can access its elements using integer-based indexing directly, without using `iloc`.

Here is an example:

my_list = [1, 2, 3, 4, 5]
print(my_list[0])  # Output: 1
print(my_list[1:3])  # Output: [2, 3]

If you are working with a Pandas DataFrame or Series object, make sure to use the correct syntax for `iloc`. Here is an example:

import pandas as pd

df = pd.DataFrame({'a': [1, 2, 3], 'b': [4, 5, 6]})
print(df.iloc[0])  # Output: a    1\nb    4\nName: 0, dtype: int64
print(df.iloc[0, 1])  # Output: 4

'Series' object has no attribute 'duplicates' 'Series' object has no attribute 'duplicates' 'Series' object has no attribute 'duplicates' 'Series' object has no attribute 'duplicates'

非常抱歉，我之前给出的答案有误。在 Pandas 中，确实没有 `duplicates` 方法。正确的方法是使用 `uplicated` 方法来检测重复值，并使用 `sum` 方法计算它们的数量。以下是正确的示例代码：

import pandas as pd

# 假设您有一个名为 dt 的 Series 对象

duplicates_count = dt.duplicated().sum()

print(duplicates_count)

请注意，`dt` 是您的 `Series` 对象的名称，具体名称可能不同。确保您使用正确的 `Series` 名称来执行这些操作。对于 DataFrame 中的列，您需要使用类似的方法来访问该列并进行重复值的计算。
