'DataFrame' object has no attribute 'max_column'
时间: 2023-12-05 16:40:55 浏览: 27
根据引用[1]和引用的信息,'DataFrame' object没有'max_column'属性。因此,如果您尝试使用'max_column'属性,则会出现类似于“'DataFrame' object has no attribute 'max_column'”的错误消息。
如果您想要找到DataFrame中的最大值,可以使用pandas库中的'max()'函数。例如:
```python
import pandas as pd
# 创建一个DataFrame
df = pd.DataFrame({'A': [1, 2, 3], 'B': [4, 5, 6], 'C': [7, 8, 9]})
# 找到DataFrame中的最大值
max_value = df.max().max()
print("Max value in DataFrame: ", max_value)
```
这将输出DataFrame中的最大值。

'DataFrame' object has no attribute 'max_row'
The 'DataFrame' object in pandas does not have an attribute called 'max_row'. However, you can achieve similar functionality by using the 'max' function in pandas to find the maximum value in a column or across rows. For example, you can use the 'max' function like this:
```python
import pandas as pd
# Create a DataFrame
df = pd.DataFrame({'A': [1, 2, 3], 'B': [4, 5, 6]})
# Find the maximum value in column 'A'
max_value = df['A'].max()
print(max_value)
# Find the maximum value across rows
max_value_row = df.max(axis=1)
print(max_value_row)
```
In the above example, `max_value` will store the maximum value in column 'A', and `max_value_row` will store the maximum value across rows.

回答: 在你的代码中,出现了两个不同的错误。首先,关于'Worksheet' object has no attribute 'set_column'的错误,这是因为你使用了旧版本的Excel文件格式(.xls)。解决方法是将文件后缀改为.xlsx,即writer = pd.ExcelWriter(r"output/XIAOBAIBAI_LOG.xlsx")。\[2\]其次,关于'AttributeError: 'Sheet' object has no attribute 'max_row''的错误,这是因为你使用了过时的方法sheet.get_highest_row()和sheet.get_highest_column()。正确的方法是使用sheet.max_row和sheet.column。\[3\]通过更正这两个错误,你应该能够成功导出Excel文件并设置列宽。
