AttributeError: 'list' object has no attribute 'intersection'

AttributeError: 'list' object has no attribute 'intersection'是一个错误提示,意味着在列表对象上使用了intersection方法,但是列表对象没有该方法。intersection方法是用于求两个集合的交集的,而不是用于列表的。
如果你想要求两个列表的交集,可以将列表转换为集合,然后使用intersection方法。下面是一个示例:
```python
list1 = [1, 2, 3, 4, 5]
list2 = [4, 5, 6, 7, 8]
set1 = set(list1)
set2 = set(list2)
intersection = set1.intersection(set2)
print(intersection) # 输出:{4, 5}
```
在这个示例中,我们首先将两个列表转换为集合,然后使用intersection方法求它们的交集,最后将结果打印出来。

AttributeError: list object has no attribute iloc
`iloc` is an attribute of a Pandas DataFrame or Series object, not a list object.
If you are trying to access a specific element within a list, you can use indexing to retrieve the element at a specific position. For example, if you have a list `my_list` and you want to retrieve the element at index 0, you can use `my_list[0]`.
If you are trying to use `iloc` on a DataFrame or Series object but are receiving this error, it may be because you are trying to apply it to a list object instead. Make sure you have properly converted your data to a Pandas DataFrame or Series before trying to use the `iloc` attribute.
AttributeError: list object has no attribute squeeze
AttributeError: list object has no attribute squeeze是因为在列表对象上调用squeeze方法,而列表对象并没有squeeze方法。squeeze方法是numpy数组对象的方法,用于从数组的形状中删除单维度条目。如果想要使用squeeze方法,需要将列表对象转换为numpy数组对象。
以下是一个例子:
```python
import numpy as np
# 将列表转换为numpy数组
a = np.array([[1, 2, 3], [4, 5, 6], [7, 8, 9]])
print(a)
# 使用squeeze方法删除单维度条目
b = np.squeeze(a)
print(b)
```
