AttributeError: 'Series' object has no attribute 'ydata'. Did you mean: '_data'?

这个错误通常是因为你在使用 `matplotlib` 绘图时,将 `Series` 对象直接传递给了 `plot` 函数。`plot` 函数需要的是 `numpy` 数组或者是列表,而 `Series` 对象并没有 `ydata` 属性。你需要将 `Series` 对象转换为 `numpy` 数组或者是列表后再传递给 `plot` 函数。
下面是一个将 `Series` 对象转换为 `numpy` 数组的例子:
```python
import numpy as np
import pandas as pd
import matplotlib.pyplot as plt
# 创建一个 Series 对象
s = pd.Series([1, 2, 3, 4, 5])
# 将 Series 对象转换为 numpy 数组
y = np.array(s)
# 绘制折线图
plt.plot(y)
plt.show()
```

AttributeError: DataFrame object has no attribute append . Did you mean: _append ?
This error occurs when you try to call the `append` method on a Pandas DataFrame object, but the object does not have an `append` attribute.
One possible reason for this error is that you are trying to append a DataFrame to another DataFrame using the `append` method, but you are not using it correctly. In Pandas, the `append` method does not modify the original DataFrame, but instead it returns a new DataFrame that contains the rows from both DataFrames. Therefore, you need to assign the result of the `append` method to a new variable or to the original DataFrame, like this:
```
df1 = pd.DataFrame({'A': [1, 2], 'B': [3, 4]})
df2 = pd.DataFrame({'A': [5, 6], 'B': [7, 8]})
df3 = df1.append(df2)
```
In this example, `df3` will contain the rows from both `df1` and `df2`.
If you are still getting the AttributeError, it's possible that the DataFrame object you are trying to append to does not have an `append` attribute. In this case, you can try using the `_append` attribute instead, which is a private method that is used internally by Pandas. However, be aware that using private methods may not be supported in future versions of Pandas and may cause unexpected behavior.
```
df1._append(df2)
```
AttributeError: 'HDUList' object has no attribute 'data'. Did you mean: '_data'?
这个错误通常出现在Python程序中,表示在一个对象上调用了不存在的属性。具体来说,这个错误提示说在一个名为'HDUList'的对象上调用了'data'属性,但是这个对象并没有这个属性,它可能只有一个名为'_data'的属性。因此,程序会建议你是否是想使用'_data'属性。
可能的原因是你在程序中使用了一个不存在的属性名或者写错了属性名。解决这个问题的方法是要检查一下代码中使用的对象和属性名是否正确,以及确认该对象是否具有该属性。如果不存在该属性,可以考虑修改代码或者查看文档以确定正确的属性名。
