要使用Python清空Excel文件,可以使用openpyxl模块来实现。首先,你需要导入openpyxl模块,并使用openpyxl.load_workbook()函数打开要清空的Excel文件。然后,使用workbook.active属性获取到当前活动的工作表。接下来,可以使用worksheet.delete_rows()或worksheet.delete_cols()方法来删除所有行或列,以清空工作表中的数据。最后,保存并关闭Excel文件即可。以下是具体的代码示例:
```
import openpyxl
# 打开要清空的Excel文件
excel_address = "示例.xlsx" #[3]
workbook = openpyxl.load_workbook(excel_address)
# 获取当前活动的工作表
worksheet = workbook.active
# 删除所有行或列以清空工作表数据
worksheet.delete_rows(1, worksheet.max_row) # 删除所有行
# 或使用以下方法删除所有列
# worksheet.delete_cols(1, worksheet.max_column)
# 保存并关闭Excel文件
workbook.save(excel_address)
workbook.close()
```
请确保在代码中将`示例.xlsx`替换为你要清空的Excel文件的路径。此代码将打开Excel文件,删除所有行或列,然后保存并关闭文件,从而达到清空Excel的目的。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
