AttributeError: 'PageObject' object has no attribute 'contents'

这个错误通常是由于代码中的某个对象没有“contents”属性而引起的。这可能是因为该对象是NoneType,或者是由于代码中的某些其他错误导致该对象未正确初始化。要解决此问题,您可以尝试检查代码中的对象是否正确初始化,并确保它们具有正确的属性。您还可以尝试使用调试器来跟踪代码并找出问题所在。如果您能提供更多的代码和错误信息,我们可以更好地帮助您解决问题。

AttributeError: 'DataFrame' object has no attribute 'append' AttributeError: 'DataFrame' object has no attribute 'append'
这个错误通常是因为pandas DataFrame对象没有append方法导致的。相反,您可以使用concat方法将两个DataFrame对象连接在一起。以下是一个示例代码:
```python
import pandas as pd
# 创建两个DataFrame对象
df1 = pd.DataFrame({'A': [1, 2, 3], 'B': [4, 5, 6]})
df2 = pd.DataFrame({'A': [7, 8, 9], 'B': [10, 11, 12]})
# 使用concat方法将两个DataFrame对象连接在一起
df3 = pd.concat([df1, df2])
# 打印结果
print(df3)
```
