AttributeError: 'MergedCellRange' object has no attribute 'contains'

`AttributeError`通常发生在试图访问对象的一个属性或方法时,但是该对象实际上并没有这个属性或方法。在这个情况下,`'MergedCellRange' object has no attribute 'contains'`错误意味着你在尝试使用`contains()`函数来检查`openpyxl`的`MergedCellRange`对象时出错,因为这个对象确实没有提供`contains`这个属性。
`contains()`方法可能是`openpyxl`的一个预期功能,但在`MergedCellRange`对象上并不直接可用。为了确认单元格是否被合并,你应该查阅`openpyxl`的官方文档,看看是否有其他适当的方法或者你需要从`merged_cells`对象的`ranges`属性中提取信息来进行判断。
例如,你可以遍历`ranges`来查找包含给定坐标的具体`MergedCell`实例,然后检查它们的状态:
```python
for cell_range in ws.merged_cells.ranges:
if cell_range.start == (row, col): # row 和 col是你想要检查的单元格坐标
# 执行合并状态的检查
break
else:
print(f"单元格({row}, {col})未被合并")
```
如果你需要确定某个区域是否全部被合并,可能需要自定义一些逻辑。

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: 'Index' object has no attribute 'contains'
AttributeError是一个常见的Python错误,它发生在试图访问一个对象的属性或方法时,但该对象实际上并没有这个属性或方法。在这个特定的错误中,"Index"对象指代的是Pandas库中的索引(Index)对象,`contains`不是一个Index对象应有的属性。通常,`contains`方法用于检查序列(如列表、字符串等)是否包含某个值。如果你在一个Index对象上调用了`contains`,可能是你需要检查的数据结构不是正确的,或者是API的使用不恰当。
例如,如果你想查找一个DataFrame中列名是否包含特定的子串,应该使用`.loc`或`.iloc`方法,而不是直接对Index操作:
```python
df = pd.DataFrame()
# 错误的尝试
index_contains_error = df.index.contains('some_substring') # 这里会抛出AttributeError
# 正确的方式
correct_check = 'some_substring' in df.columns # 或者
correct_check = df.columns.str.contains('some_substring')
```
